If we are unable to verify a certificate-requesting entity's domain registration and domain control via the Whois database (generally because the information in the Whois database cannot be found or does not match the information in the certificate request), the requester must instead provide a Domain Authorization Letter from his/her domain registrar as documentation of domain registration ownership. If we successfully authenticate the letter, a Registration Authority (RA) associate manually verifies domain control.

To obtain a Domain Authorization Letter, you must request it from your domain registrar. Consult your registrar for specific instructions.

If the domain in the certificate request is hosted with our Domains By Proxy affiliate, log in to your Domains By Proxy account and request the Domain Authorization Letter. Domains By Proxy prepares the letter within 48 hours of the request.

Once you have obtained the Domain Authorization Letter, please fax or scan-and-email it to us as proof of domain registration ownership. An RA associate reviews the letter upon reception.
