21 CFR § 1311.20 - Coordinators for CSOS digital certificate holders.
(a) Each registrant, regardless of number of digital certificates issued, must designate one or more responsible persons to serve as that registrant's CSOS coordinator regarding issues pertaining to issuance of, revocation of, and changes to digital certificates issued under that registrant's DEA registration. While the coordinator will be the main point of contact between one or more DEA registered locations and the CSOS Certification Authority, all digital certificate activities are the responsibility of the registrant with whom the digital certificate is associated. Even when an individual registrant, i.e., an individual practitioner, is applying for a digital certificate to order controlled substances a CSOS Coordinator must be designated; though in such a case, the individual practitioner may also serve as the coordinator.
(b) If the designated coordinator changes at any time, the Certification Authority must immediately be notified of the change and the new responsibilities assumed by each of the registrant's coordinators, if applicable. New Coordinators must complete the online application as provided in § 1311.25.
(c) The registrant's coordinator must inform the Certification Authority of all digital certificate applications, renewals and revocations for the registrant's users and approve applicants applying for a power of attorney digital certificate for a DEA registrant by means instructed by the Certification Authority within the system.
