CSOS Certificate Revocation

Certificate revocation results in the loss of ability of the digital certificate holder to use the certificate for electronic ordering purposes by placing the certificate information onto a “Certificate Revocation List,” or CRL, that relying parties (people who accept your digital certificate) are required to check.

Certificate revocation must be requested when the subscriber's private key is lost or compromised, when ordering authority or affiliation has changed, or when the subscriber's name changes.

Revoke CSOS certificate(s)


CSOS Certificate Renewal

CSOS Signing Certificates expire when the associated DEA Registration expires, and must be renewed in addition to the DEA Registration (also referred to as the DEA license or Form 223).

The CSOS Registration Authority will notify the subscriber via E-mail 45 days prior to certificate expiration. Follow the Renew CSOS Certificate(s) link for more information.

CSOS Records Information Change

Information change requests should be made for CSOS Coordinator role changes and for changing subscriber contact information not contained in the subscriber's CSOS digital certificate (i.e., phone number, business address, and business name). Information change does not affect the information contained in a CSOS digital certificate.
