Data validation on the WHOIS

Please note our data validation processes change on 6th May 2015 – this section describes how these processes will operate from the 6th May

The data validation status of the registrant is published on the WHOIS.

The data validation text appears below the registrant’s address details or underneath the Service Address, where this is required for second level .uk domains.

Where existing data requires validation we will encourage the registrant to update the data either through Online Services or through their registrar if appropriate.

Accredited Channel Partners may choose to confirm to us when they have been successful in validating registrant details for a domain. This will result in the WHOIS entry showing as ‘The Registrar is responsible for having checked these contact details’ immediately, rather than ‘Nominet was not able to match the registrant’s name and / or address against a 3rd party data source on DD-Month-YYYY’ for 30 days. Please see the automaton and EPP instructions on how to positively validate your data.

The data validation output will be displayed on the WHOIS as follows:
