The registry operator conducts weekly random checks for US nexus requirements. They select a small sample (approximately 0.5% of new registrations) and send the selected registrants a Nexus confirmation email (attached to this article).
Each selected registrant will have 30 days to respond to the registry operator. If the registrant fails to respond, the registry operator will attempt a second contact with the registrant. If there is no response to the second contact, the registry operator will delete the domain name. The registry operator is not refunding registration fees for deleted names.
Tucows will receive a copy of any Nexus Confirmation emails sent to domain names registered under our accreditation. We anticipate this will affect only small numbers of registrants.
