Validating your certificate could not be successfully completed
While the paper DEA Form-222 ordering process is still allowed, CSOS is the only method for ordering Schedule I and II controlled substances electronically.
The benefits of CSOS for end users include: Back to Top There is no charge by DEA for CSOS Certificates or for participating in any aspect of the CSOS program.
Back to Top A separate CSOS Signing Certificate is required for each DEA Registrant number.
In cases where a person represents multiple Registrants or DEA Registrant numbers, then multiple Certificates will be issued.
Back to Top There are two types of CSOS Certificates: Each CSOS Certificate (both Administrative and Signing) are issued to individual subscribers.
Certificates must never be used by anyone other than the individual subscriber (a person, not a location) the certificate was issued to.
CSOS Certificates are issued to individuals and are required for electronic ordering of Schedule I and II controlled substances.
Only one Principal Coordinator and one Alternate Coordinator may be enrolled in CSOS for any one DEA Registration number.
Enrollment in CSOS by the Registrant is optional, and should be limited to only those Registrants who sign controlled substance orders or wish to be Coordinator for his/her organization.
The DEA Registrant must name a CSOS Coordinator on his/her CSOS application.
In this case, Power of Attorneys would represent multiple Registrants to consolidate the ordering process and each purchaser would need a separate CSOS Certificate for each DEA Registrant.
