Afnic, the registry that manages the French ccTLD .fr, made the following announcements in regards to the eligibility criteria for .fr domains:
For our UK clients who own .fr domains that were registered prior to 1 January 2021, no action is needed and your domains will remain valid. If a UK client wishes to register a .fr domain in the future, we offer a local presence service to ensure your registration meets the new eligibility requirements.
If you have any questions, please contact your Account Manager or [email protected].
