Controlled Substance Ordering System (CSOS) allows for secure electronic transmission of controlled substance orders without the need for the paper DEA Form 222. Each individual purchaser enrolls to receive a Digital Certificate that provides a digital signature. Once enrolled, CSOS subscribers have ordering freedom to complete orders electronically with no line item limit for a single order. Using CSOS will simplify the ordering process; faster transaction, order accuracy, and decreased paperwork.
How do I enroll in CSOS?
To get a digital certification, a DEA registrant must enroll in the CSOS program through the DEA website. Generally, the registrant is the person currently responsible for signing the DEA Form 222.
