Nominet, the .UK registry, has introduced a new Data Quality Policy. This policy requires that both the registrant name and address be verified against a third-party data source. For each domain registration or update, Nominet will try to validate the registrant name and address using their own data sources. If Nominet is not able to complete this validation, they will ask the registrar to have the data verified. Domains that do not complete the verification within 30 days will be suspended and can no longer be renewed or transferred.

Nominet will require registrars to enforce this policy starting September 22, 2014.
OpenSRS will start sending out .UK verification emails to registrants on October 2, 2014.
