URLs help users to navigate, to understand what content they can expect, but it also structures the domain. For this reason, the EC, Parliament and the Council agreed on common rules on URLs in 2005.

A coherent common structure enhances the user experience by its transparency and reinforces the trust in the sites under it. The web address is a guarantee of trustworthiness and reliability.


According to Europa domain and subdomains rules, websites owned by DGs and executive agencies must be hosted on the europa.eu domain. 

As part of the Europa.eu domain, the websites’ URLs must follow the below rules:

Translated pages must have exactly the same URL of the original page, with the addition of suffix at the end of the page name.

For example:
ec.europa.eu/info/my-page → points to the English page
ec.europa.eu/info/my-page_en → English page
ec.europa.eu/info/my-page_de → German page
ec.europa.eu/info/my-page_sl → Slovenian page

The permitted suffixes for Eu-languages are the following (taken from alpha-3/ISO 639-2 Code)

Bulgarian: bg
Spanish: es
Czech: cs
Danish: da
German: de
Estonian: et
Greek: el
English: en
French: fr
Gaelic: ga
Italian: it
Latvian: lv
Lithuanian: lt
Croatian: hr
Hungarian: hu
Maltese: mt
Dutch: nl
Polish: pl
Portuguese: pt
Romanian: ro
Slovakia: sk
Slovenian: sl
Finland; fi
Swedish: sv

When listing the available languages, Spanish comes directly after Bulgarian (because of castillian spanish). Nevertheless the prefix is _es and not _cs

For non-EU languages, the following suffixes must be used:

Arabic: ar
Chinese (simplified): zh-hans
Chinese (traditional): zh-hant

For other languages, see the file DGT-languages

Note: URLs  of the European Commission's websites can be structured in two different ways depending on the hosting: 


Some elements used in brand names could negatively impact how search engines work and how people perceive your domain name. 

Therefore, we recommend while defining the URL to: 

Printing URLs

In case you need to print or advertise or publish URLs, always use lower case (e. g. ec.europa.eu and not Ec.europa.eu nor EC.EUROPA.EU.

Drupal Instances

Urls containing the node keyword should rewrite to the human-readable version of the url. For example:

ec.europa.eu/drupalInstance/folder1/node_en → ec.europa.eu/drupalInstance/folder1/title-of-the-page_en


The Commission services requesting for a URL/site name must always complete the necessary copyright checks on the names or association of words they intend to use before sending their request. For more information, contact the Intellectual Property Office (EC-IPR@ec.europa.eu).
