All Commission websites must be hosted on europa.eu, according to Europa domain and subdomains rules.
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.
Translated pages must have exactly the same URL of the original page, with the addition of suffix at the end of the page name.
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)
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:
Chinese (simplified): zh-hans
Chinese (traditional): zh-hant
For other languages, see the file DGT-languages
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)
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
