All suppliers must submit CSOS transaction data to DEA using the CSOS EDI Reporting format. CSOS transaction reports must be submitted to DEA within two (2) business days of order fulfillment via a secure Web site that requires CSOS reporters to authenticate themselves with a username and password.

Each supplier must enroll in the CSOS EDI Reporting program to acquire an EDI account. Suppliers authorized for central reporting will be issued a single EDI account. Organizations not registered for central reporting will be issued an account for each reporting facility.
