Rules

All Commission websites must be hosted on europa.eu, according to Europa domain and subdomains rules.

In addition: 

  • URLs must always be lower case (to avoid incompatibility between Unix and Windows, respectively case-sensitive and case-insensitive)
  • URLs must always be in English, even when they contain a page in another language (see also Language indicator)
  • multiple words contained in a URL must be separated by a dash/hyphen (-), though the underscore (_) is also accepted
  • URLs must not contain chained multiple words (e. g. europeancommission is wrong, european-commission is correct)
  •  URLs must not contain acronyms, as they are not understood by a broader audience. Exceptions can only be granted for existing URLs already approved in the past.

4th level domains in ec.europa.eu

Executive agencies of the European Commission and Commission websites with specific technical requirements (such as secured and cloud hosting) can have their own fourth level domain name within the third level domain ec.europa.eu.

Language Indicator

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

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-readible version of the url. For example:

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

Guidelines

  • if possible, avoid using stopwords (e. g. "and", "or", "but"...) in URLs
