Certificate Renewals

All certificate types must be renewed every three years.

If the secure and verifiable form of identification on file with our office has expired, the Colorado Revised Statutes require individuals applying for or renewing certificates to provide a current secure and verifiable form of identification. A list of acceptable forms of identification can be found on the Affidavit of Lawful Presence.
