ICANN are the main authority for all top level domain names. Their policy now requires all registrars (Us) are now required to validate a registrant's (You) email address before changing it. Registrars are now required by ICANN to suspend any domains that are not validated within 15 days of being asked to do so.
When will I need to validate my domain?
- If you have registered a domain name since 1st January 2014
- If you have updated any contact information since 1st January 2014
- If you have attempted to transfer your domain since 1st January 2014
