    • What is a domain name?
      A domain name is a name that is easily memorized and is used to locate and identify computers on the Internet.
      e.g. dns.pt; google.com; rtp.pt; icann.org;
    • How can I register a domain name under .pt?
      To register your domain you may use entities that are specialised in this field, REGISTRARS, or submit a request directly at www.dns.pt.
    • What's a "3em1" domain name?
      A "3em1" domain name is a domain registered under the national initiative "Empresa, Associação ou Sucursal na Hora" and that complies the terms and conditions available at www.3em1.pt.
  • Registering New Domains
    • Can I choose any domain name?
      In .pt, org.pt e com.pt it will be made an a posteriori monitoring, in order to verify the compliance with the rules for registering .pt domain names, whereby, upon submitting a domain, it should be guaranteed that it is not a domain prohibited or does not conflict with a right of a third party. Prohibited domains are those that:
      • Correspond to words or expressions contrary to law, public order or morality;
      • Match any top level domain of the Internet;
      • Correspond to names that mislead or confusion about its ownership, namely by coinciding with notorious or prestige trademarks belonging to others;
      • Correspond to any protocols, applications or terms of the Internet, which are understood as those defined by the IETF - The Internet Engineer Task Force;
      • Contain two hyphens "-" in the third and fourth positions;
      • Correspond to a geographic term, as referred to in paragraph f), number 1 article 9.º;
      In the classifier .edu.pt, .PT may make an a posteriori check on the legitimacy basis for registration and, in general, for the above.
    • The name I want is already registered by another entity. What can I do?
      If the name you want to register is taken, you can:
      1. Choose to register a different domain name;
      2. Choose to register in a different .pt classifier, if that is possible and if the name is available;
      3. If you are the holder of a previous right, appeal to the Arbitration process, if you believe that there is a dispute over that domain name and legitimate conditions exist to believe that it should be attributed to you.
    • Which are the .pt sub-domains/ classifiers?
      Apart from registration directly under the .pt TLD, there are 4 official .pt classifiers: .gov.pt, .org.pt, .edu.pt and .com.pt.
    • I have a domain registered in (. Net.pt, .Int.pt, .Publ.pt, .Nome.pt), what will happen to my domain?
      These classifiers were eliminated, new registrations will no longer be accepted, however, the previously registered domains will continue to exist.
    • Which classifier can I choose?
      Registering domains in a particular classifier depends on the type of registrant and the basis for registration. Although it is advisable to read the rules, the general requirements for each type of registration are shown below.
      • .PT - Domain names under .pt may be registered by all individual or corporate entities.
        In the case of geographic names, these can only be legitimately registered by the legal administrative authority, as stated in paragraph b) article 11.
      • .GOV.PT - limited to entities that are part of the Government structure of the Portuguese Republic;

      • .ORG.PT – limited to non-profit organizations and projects;

      • .EDU.PT – limited to public teaching establishments and owners of private and co-operative teaching establishments;

      • .COM.PT – there are no limitations regarding the registrants, as any individual or corporate bodies may register;
    • If I choose the wrong classifier, what happens to my request?
      The domain will be removed within the terms of article 22 of the .pt Domain Registration Rules.
    • How can I find out if a trademark exists with the same name that I want to use to register my domain and vice-versa?
      You can carry out a complete search of domains and trademarks, which are freely available online at www.dns.pt and/or www.inpi.pt.
    • It is necessary to send any documentation with my domain registration?
      It is not necessary to send any documentation with the registration, as the registrant assumes the responsibility for the information registered and for complying with the rules. With the a posteriori monitoring and assessment, documentation may be requested to verify conformity, as set forth in article 22 of the rules.
  • Changes to registered domain names
    • Can I change the name of my domain?
       No. The process for changing a domain name entails the removal of the previous domain and request of a new one.
    • What is a Nic-Handle?
      A Nic-handle is the unique identifier used to associate a contact in the process file of a domain. These should be used, whenever possible, in the domain registry, they save time and help to ensure consistent and accurate information. In the case of online services they also allow to have a consolidated view of information about the domains to which they are associated.
      Whenever a new contact is created online, it is assigned a Nic-handle that contact and a notification is sent with its details.
    • How do I create a contact?
      The creation of a contact (and its Nic-handle assignment) can be done in the "Entities" -> "Create User / Entity."

      We alert to the fact that it should not be made the creation of nic-handles for entities / persons who already have a nic-handle in our system, so as to avoid duplication.
    • How can I make changes to the details of my domain and the contacts?
      Changes must be carried out online using the access credentials that were attributed to you.
    • How can I recover or change my password?
      To recover the password, the user must go online and carry out the respective request, by using the entity/person's nic-handle, username or VAT number.

      After making your request, at the email address associated to the contact, you will receive the username and a link to indicate a new password. This link is valid for a maximum of 5 days and it may only be used once.
    • What if I don't remember the nic-handle, username and VAT number?
      In the event of the user not having any of the identifiers (nic-handle, username or VAT number) or if the email associated to the contact is out of date, he or she should contact the .PT Domain Registration Service who will provide you the necessary details after confirmation of legitimacy.
    • May I transfer the ownership of my domain to another entity?
      Yes, however to make the same is necessary to refer the following elements:
      • Statement of transfer duly issued by the current registrant, identifying the domain name, the current registrant and the new registrant entity;
      • Nic-handle holder of the new registrant entity;
      • Statement relative to the acceptance of the arbitration agreement, issued by the new registrant entity.
    • Can I transfer the management of my domain?
      Yes, the registrant of the domain accesses online  at www.dns.pt with the respective Username and Password, then accesses the process file and generates the "authorization key", in the button "actions" "transfer domain management", providing it to the new administrative contact;
      • The new administrative contact accessing online at www.dns.pt with respective Username and Password, clicks the link "domain transfer key" then places the domain name and key provided by the registrant of the domain, confirms the change and the transfer domain is processed immediately.
      Features of the key to change the management:
      • It is associated with only one domain name;
      • It can be used only once;
      • It is valid for 30 days,
      • If given the intention to generate new code, the previous automatically expires (if still valid).
    • How can I remove my domain?
      Preferably, the registrant or the administrative contact can request the removal of the domain online, using the respective username and password.

      You may also request such removal by email to the contacts indicated on our web page.
  • Renewal and payments
    • How much does a domain registration cost?
      The price of registering and maintaining domain names is as follows:

      - VAT at the legal rate is added to these amounts (According to national and to EU regulation);
      - Changes made by the .PT: whenever changes to the information on the domain's file are carried out by the .PT, the unit value of those changes is 15.00€;
      - Registrars are responsible for all the payments to .PT applicable to their domain registration. The amount billed by .PT to Registrars is €8.75+VAT/domain name.
      - The maintenance fee covers the costs of registration, management and maintenance of the domain. 
    • Which contact is responsible for the payment?
      The Administrative Contact, which may coincide with the registrant, is responsible for the payment and in whose name the invoices/receipts are made out.
    • What methods of payment are available to me?


       You will be provided with a reference to use in order to pay at an ATM – service payment or using your home banking.

       Use online payment with your credit card.

       Use online payment with the popular payment website

    • What happens to my domain if it is not renewed?
      Failure to renew a domain by the end of its period of validity implies its expiry.

      .PT always notifies about the necessity to renew the domain and the expiry date.
  • Technical FAQs
    • Is it necessary to carry out a technical configuration and have a name server to register a domain name?
      No, but the domain name will not be activated. For this, some name servers need to be correctly configured. If you do not have any technical knowledge on this matter you should contact a specialist in this field.
    • How can I confirm if my domain name is properly configured?
      A DNS Evaluator Tool it at your disposal. By simply inputting the domain name and IP address /primary server's name, you can find out if it is properly configured.
    • Can I put my web server in the .pt domain registration system?
      This is not directly related to our services. The service of .pt registration does not make the delegation of domains for web servers, but to name servers, so, the data provided in the system must relate to the name servers.
    • What is required to use the domain name on the Internet?
      Before a domain can be used on a web page, e-mail or other services, it is necessary to have name servers configured for it. The web and e-mail servers will also have to be configured.

      In most cases, the hosting provider provides service packs that include all these issues. The .PT service (registry) does not provide these services, but you can consult the list of registrar entities.
    • I found that a domain is registered but has no webpage, this is valid?
      The .PT rules foresees that in the case of registrations of domain names solely for the purposes of reservation of the name, the maintenance process does not imply compliance with technical conditions, so in these cases, the domain is not visible on the internet and thus there are no services associated with it, such as web pages or e-mail.

      Another possible scenario may be that the domain is delegated to the respective name servers, but does not have any web server set for it.
    • My domain is already active but the website does not work, why?
      If the domain has just been technically evaluated with a positive result, the status changed to active, you should wait a few hours, in order that the domain is available on the Internet and its propagation is made. In this way, if properly configured the in the name servers, the services associates to the domain will become visible.
    • In the .PT domain system there is only one field to indicate the technical data, how can I specify the secondary DNS for the domain?
      In the .PT domain system, when the technical data the primary DNS server (IP address or server name) is indicated, a technical evaluation is made automatically by the system for the respective domain. Within the configuration found, besides the information relating to the primary itself, there should be information about the secondary server(s), in this way the system obtains the necessary data.

      We alert to the fact that all secondaries will also be evaluated and thus all must be correctly configured for the domain.
    • How to Change Resource Records of domains that are active?
      If there is change of the primary DNS server, it will suffice the indication of the new data (numeric IP address or e-names) in our system, for it to automatically recognize the need to evaluate the domain. If the primary name server does not change, but there are changes in the configuration in this server or the in the secondaries is necessary to make an application for an evaluation in the online .PT System.
    • What is IPv6?
      Internet Protocol version 6 or IPv6 (also previously referred to as IP new generation or IPng) is meant to support the continued growth of the Internet, both in terms of size and functions. In relation to IPv4, it provides a considerably larger address space, as well as other improvements. For further information about the DNS service in Ipv6 see RFC1886 at http://www.ietf.org/rfc/rfc1886.
    • What is DNSSEC?
      cDNSSEC is the name given to the security extensions to the DNS protocol and was created to protect and authenticate DNS traffic. These extensions seek to validate data by means of digital signatures, using asymmetric key-cryptography. For further information go to www.dnssec.pt.
    • Can I change my domain's server when I use a registrar?
      If you nominated an administrative contact for your domain, it is their responsibility to carry out all the necessary changes.
  • Arbitration (Alternative Dispute Resolution)
    • What is the arbitration procedure?
      The arbitration procedure consists of an extra-judicial mechanism for resolving disputes, whereby, in the event of a dispute over domain names, the registrants or applicants of a domain name and .PT, as the .pt registry, agree to turn to voluntary institutionalised arbitration according to Voluntary Arbitration Law and for which the authorised Arbitration Centre is ARBITRARE. For further information: www.arbitrare.pt.
    • Against whom can I file an arbitral case?
      Arbitration applies to situations of non-conformity regarding a domain name and may be requested by any interested party:
      a) Against the registrant of the domain name which is the object of arbitration; or
      b) Against the Registry (Associação DNS.PT, .PT), for the removal or registration acceptance of a domain name;
    • I have accepted arbitration. May I turn to other means of dispute resolution at the same time?
      Yes, you can judicially contest the arbitral decision.
  • Glossary of .pt domain name Technical Status
    • Glossary of .pt domain name Technical Status
      • Stand-By-Payment - Process awaiting payment of the registration and maintenance fee within 48 hours. If payment is not made within this deadline the domain expires.

      • Rejected - Process which, following legal assessment, does not meet the necessary conditions for its approval.

      • Active - Domain that has been approved and becomes accessible on the network once the technical information has been indicated.

      • Reserved – Exactly as "Aproved" but where there are no technical details. It will not be activated.

      • Tech-Pro - Domain that has been approved but has technical irregularities which prevent it from being activated. (e.g. Primary IP Server not configured or incorrectly configured).

      • Expired - Process expired due to renewal/payment failure.

      • Pending-Delete – The domain is in a state of pre-removal, during which time it is neither assigned nor active, but may be recovered again by the same registrant.

      • Deleted - Domain removed following request by the registrant, registrar or on decision by the .PT or competent legal authority.
  • Other Information
    • How can I register a domain name under .com or another TLD?
      The .PT only manages the .pt top level domain, so registration under .com, as well as any other TLD must be carried out with the accredited entities for this. For further information, go to the website www.iana.org.
    • How do I register a domain under .gov.pt?
      Registration under the .GOV.PT hierarchy must be carried out at www.ceger.gov.pt.
    • For how many domains can an entity be the registrant?
      There is no limit.
  • Registration of domains with two characters
    • What is a .pt domain with two characters?
      It is a domain whose name that comes before the country code, in this case .pt, is comprised of only two letters, or two numbers or the combination of a letter and a number. For example: xs.pt or ç2.pt.
    • How do I know what technical, material and legal conditions apply to the registration of domains with two characters?
      When the new .pt Domain Name Registration Rules came into force on 16th June last, it was publicly announced that as from 1st November it would be possible to register domains with two characters. A campaign is currently running in the media and online where all the information on this matter is available.

      The applicable conditions for registering domains with two characters are available online at www.dns.pt
    • If I have any queries about this matter who should I contact?
      Preferably contact via email (request@dns.pt), blue line phone number: 808 20 10 39 (from Portugal) +351 21 313 57 37 (from abroad), (service timetable: working days from 8am to 8pm) or FAX: 211 31 27 20
    • As from when can I register domains with two characters under the .pt ccTLD?
      As from 9 a.m. on 3rd November you can register any of the domains which are listed in paragraph 1 of the Annex to the applicable Conditions for registering domains with two characters, which is available online www.dns.pt. The domains mentioned in paragraphs 2 of the above-mentioned list will be auctioned between the 4th and the 11th of December.
    • What is the price of a domain with two characters?
      The initial annual fee is €100. At the end of this period the conditions in force for domains with more than two characters are available here.
    • Why is the price of registering a domain with two characters higher than that for other registrations?
      Domains with two characters are treated as premium domains from the outset due to the limited number of possible combinations that can be registered, and also this measure aims to rationalise the market and enable greater distribution of this type of domain.
    • Can I register any name as long as it has two characters?
      No. In terms of name composition, this type of domain is subject to the terms and rules for composing names with a higher number of characters and which are set out in articles 8 and the following of the .pt Domain Name Registration Rules. Namely, geographical names or those coinciding with existing ccTLDs will not be accepted.
    • Can all the names that are listed in the Annex to the applicable Conditions for registering domains with two characters be registered?
      .PT has endeavoured to produce an accurate and objective list of the domains with two characters that may be registered as long as the respective, associated, technical and financial conditions are met. Nevertheless, there may be conditioning factors that we are unaware of from the outset and which may come to hinder such registration. We could mention, purely as an example, previously registered notorious brands. .PT guarantees, however, that only the rules that are general knowledge today and available at www.dns.pt will always be applied.
    • How can I take part in the auction?
      All the information on how to take part in the auction is available at www.sedo.com . It is mandatory and a condition for taking part in the auction for anyone interested in bidding for domains on the platform www.sedo.com to firstly register on that platform.
    • What happens if a domain goes up for auction and nobody bids?
      Once the period of time set for each of the auctions has ended, the domains that are not sold become available, within the same conditions as those that did not go up for auction, namely in terms of price.
  • DNSSEC - Domain Name System Security Extensions at .pt
    • What is DNSSEC?
      DNSSEC is the name given to security extensions to the DNS protocol and was created to protect and authenticate DNS traffic.

      These extensions seek to validate data by means of digital signatures, using asymmetric key-cryptography.
    • What is the purpose of DNSSEC?
      The additional security provided by using DNSSEC extensions to the DNS protocol make it possible to:
      • Overcome vulnerabilities;
      • prevent attacks;
      • reduce the risk of manipulation;
      • provide a secure service;
      • reinforce security.
    • If I sign my domain name, how does this protect me?
      These security extensions to the original protocol consist of a hierarchy of cryptographic signatures that authenticate the origin of the DNS data, and the integrity and authentication of the reply denying the existence of a domain.

      These measures protect against corruption of cache memories and modified transmissions and contribute to increasing trust in the Internet and its systems.
    • What are the new Resource Records?
      The real function of DNS is to match domain names to their corresponding Resource Records. These are divided into classes and types, and a wide variety of types currently exist.

      A group of Resource Records with the same domain name, class and type is known as a Resource Record Set (RRset).

      Among the commonest types of resource records are SOA records that indicate where the zone authority is delegated, NS records that indicate a name server for the zone and A records that attribute a name to an IP address.

      DNSSEC introduces additional Resource Records, which are divided into four different types:
      • DNSKEY - Public key;
      • RRSIG - Digital Signature of the RRset;
      • NSEC/NSEC3 - Authenticated denial of the existence of a domain or Resource Record Set associated with a domain;
      • DS - Fingerprint of the public key that links a domain and sub-domain so as to create a chain of trust.
    • What is cryptography?
      Cryptography is a science that makes it possible to write in a way that hides the content. The objective of cryptography is to enable a limited set of entities, typically two, to exchange information that is unintelligible to third parties or to save and transmit private information on open networks (such as the Internet) without the risk of it being read or modified by anyone other than the intended final recipient of the message.

      Cryptography is based on the use of ciphers. A cipher is a specific cryptography technique i.e. a specific way of hiding information.
    • What exactly is asymmetric cryptography?
      Asymmetric cryptography, or public-key cryptography, uses a pair of distinct but related keys: a public key for encrypting and a private key for decrypting; it is not possible to calculate the private key from the corresponding public key. Ciphers also allow reverse encryption i.e. encrypting with the private key and decrypting with the public key, which is not very useful for concealing information but is useful for guaranteeing authorship of the information.

      Pairs of asymmetric keys are personalised i.e. they are associated with people, services or servers. The private component must be kept secret and should only be known and used by the entity with which it is associated. The public key may (and should) be widely and publicly distributed so that it can be used by any entity.

      In operational terms, the main advantage of asymmetric ciphers is the fact that they require fewer keys to effect secure exchanges because they permit a relationship of many to one.

      In administrative terms, the main problems underlying the use of asymmetric cryptography are:
      • Stringent restriction of private keys to their legitimate owners;
      • Reliable distribution of public keys to all who wish to use them;
      • Control of the lifetime of pairs of keys.
    • What is spoofing?
      A spoofing attack is a situation in which an entity (person or program) disguises itself as another by falsifying the DNS data so as to gain an illicit advantage.
    • What is pharming?
      Pharming is an attack characterised by poisoning of the DNS cache which consists of corrupting the DNS of a network so that the traffic of a web page is redirected to another.
    • What is phishing?
      Phishing is a method of electronic fraud characterised by an attempt to acquire sensitive information such as user names, passwords, credit card details, etc, in which the attacker poses as a trusted entity via disguised electronic communications.
    • Is response time increased with a signed zone?
      The use of DNSSEC involves an exchange of messages of larger dimensions. In reply to data requests in signed zones, DNS servers with security support will reply with DNSKEY, RRSIG, NSEC3 and/or DS resource records. The addition of these new RRs requires the allocation of greater bandwidth to exchange messages between the server and the client. However, the vast majority of requests initially made to signed zones will be made by clients that do not support security extensions and those additional resource records will not provide any advantage to those clients or increase response times.

      In terms of the response capacity of a DNS server with DNSSEC implementation, although there is an increase in access time to the DNS from a signed domain, this is not significant from the point of view of the end user detecting any impact on the response time because we are talking about values of the order of milliseconds.
    • DNSSEC keys submission/update (DS resource record)

      For the submission, update or removal of DNSSEC keys (DS resource record) of a domain that is active under the .pt zone, this procedure should be made through the .pt domains management system, reserved area.

      To configure the DNSSEC information, through the .pt domains management system, you should access as the technical contact of the domain name to be configure.

      1) Login as the technical contact;
      2) Go to the menu "Domains";
      3) Select the domain to configure;
      4) In the domain detail page, select the menu "Technical Settings";
      5) Through the tab menu "Technical Settings" there are two ways to add DNSSEC information, being recommend the automatic method, described below as option A):
          A) Automatic Fetch Configuration:
                - Select the option "Automatic Fetch Configuration";
                - Insert the a authoritative name server for the domain;
                - Select "Fetch";
                - Confirm if the fetched information is the intended one, regarding name servers (NS) and DNSSEC keys (DS);
                - If so, "Save".
          B) Manual Configuration:
                - Select the option "Manual Configuration";
                - Use the button "Add DNSSEC Configuration";
                - Add the hash data of the key(s) KSK into the proper fields, manually;
                - If you intend to add more than one resource record DS choose "Add new DNSSEC record";
                - After you finish editing you need to "Save DNSSEC";
      6) The new technical information, either obtained automatically or entered manually, will only take effect in the next .pt zone generation and delegation, that occurs automatically at specific time periods.
