Rules for domain names

Please read the Terms and Conditions and Registration Policy regarding domain names under the .eu, .ею (Cyrillic script) or .ευ (Greek script) extensions. You can also read more about the EU Regulations.

Changes to the eligibility criteria

The new .eu Regulation was published on 29 March 2019 in the Official Journal of the European Union. The new Regulation will repeal previous Regulations and enter into force from 13 October 2022, with the exception of Article 20 that introduces eligibility for EU citizens residing in third countries.

Article 20 of the new Regulation introduces the updated eligibility criteria. As of 19 October 2019, registration of .eu domain names can be requested by any of the following:

  • an EU citizen, independently of their place of residence;
  • a natural person who is not an EU citizen and who is a resident of a Member State;
  • an undertaking that is established in the EU; or
  • an organisation that is established in the EU, without prejudice to the application of national law.

Furthermore, bear these rules in mind when deciding which domain name you would like to register:

Accepted characters and combinations

Classic (Non IDN) domain names consist of:

  • Characters a to z
  • Digits 0 through 9
  • Hyphen (-)
  • Can only be registered under the .eu extension
  • Cannot start nor end with a hyphen (-)
  • Cannot have a hyphen in third and fourth position.

IDNs consist of:

  • Digits 0 through 9
  • Hyphen (-)
  • Unicode characters from the Cyrillic, Greek or Latin scripts.  Click here for a complete list of supported characters.
  • Cannot combine characters from different scripts.  All the characters of the second level (ie. the part before the extension) must come from a single script.  Domain names made up of Latin characters will have the .eu extension, while domain names made up entirely of Cyrillic characters will have the .ею extension and and domain names made up from Greek characters will have .ευ extension. The digits 0 through 9 and the hyphen can be used with all Latin, Cyrillic and Greek characters.
  • Cannot start nor end with a hyphen (-).
  • Cannot have a hyphen in third and fourth position.

Exclusively numerical domain names:

  • Consist solely of the digits 0 through 9 and the hypen.
  • Can be registered under the .eu as well as the ею or .ευ extensions.

Name length and IDNs

Your domain name must be at least two (2) characters long (not including the .eu extension or its variants in other scripts) after the conversion of capitals into small letters and normalisation has occurred. If you want to register an IDN, apply this rule before converting your name into an ACE string. Some names are still considered too short even though they are two characters long. This is because certain two-character combinations can also be represented as a single Unicode character.

Your domain name can't be longer than 63 characters (not including the .eu extension or its variants in other scripts) after the conversion of capitals into small letters and normalisation has occurred and after conversion into an ACE string.

Expiry date of domain names

Since 15 September 2014, newly registered domain names no longer expire at the end of the month and instead do so at the end of their registration term, calculated in years starting on the registration date and ranging from one (1) to ten (10) years. Domain names registered on 29 February always expire on 28 February.


Situation after 15 September 2014 (for new domain names registered after 15 September 2014)
Registration date = 15 January 2015
Expiry date = 15 January 2016 (= 15 January 2015 + 1 year)

Blocked names

Certain .eu domain names have been blocked by the EU Member States or the EU institutions. This means that they may not be registered.

Many two-letter country codes, such as BE for Belgium or DE for Germany, have been blocked as well. You can view the list of blocked names here. The list is not exhaustive and does not contain the blocked two-letter country codes.

Reserved names

A number of .eu domains have been reserved for use by either the European Union institutions, one of the EU Member States, EEA countries, countries in the EU accession phase or EURid.

For more information, please refer to our leaflet on reserved names and to EC regulations 1654/2005 and 560/2009. A corrigendum to Commission Regulation (EC) No 560/2009 of 26 June 2009 amending Regulation (EC) No 874/2004 can be consulted here.

Following the introduction of the IDNA2008 protocol, the list of domain names reserved by Member State was updated and annexed to Regulation 516/2015.

EURid has reserved the following names for its own use:


Should there be organisations or private persons wishing to register a reserved domain name, the respective National Registration Authority might consider, under exceptional circumstances, activating the reserved name on behalf of the applicant. For more information, please consult the activation procedure for reserved names.
