Welcome to the DEA Office of Diversion Control – Controlled Substance Ordering System (CSOS) Pilot Program
The Controlled Substance Ordering System (CSOS) allows for secure electronic transmission of controlled substance orders without the supporting paper Form 222. The adoption of CSOS standards is the only allowance for the electronic transmission of Schedule II controlled substance orders between controlled substance manufacturers, distributors, pharmacies, and other DEA authorized ordering entities. CSOS uses Public Key Infrastructure (PKI) technology, which requires CSOS users to obtain a CSOS digital certificate for electronic ordering.
The CSOS Pilot Program allows participants to acquire CSOS Digital Certificates for testing purposes only.
DEA Diversion E-Commerce Support is available to assist with all CSOS related questions.
