Reporting Frequency

ARCOS registrants (participants) must report quarterly. However, participants may elect to report more frequently on a monthly basis. Those registrants wishing to change their reporting frequency must file a written request with the DEA (ARCOS) before submitting reports according to the new frequency. Requests for a change in reporting frequency must be submitted on company letterhead and may be sent by mail or fax to the ARCOS Unit at:

ARCOS Registrants and Reporters

An ARCOS registrant is a manufacturer or distributor required to report controlled substance inventories and transactions to DEA. There are three types of ARCOS reporters: (1) single reporters, (2) registered central reporters, and (3) non-registered central reporters.

Single Reporter

An ARCOS registrant reporting only its own controlled substance transactions and inventories to DEA (ARCOS) is a single reporter. If an ARCOS registrant is a subsidiary of a larger corporate entity and submits its own ARCOS reports, it must follow the instructions for a single reporter.

Registered Central Reporter

A registered central reporter has a DEA registration as a manufacturer or distributor and reports controlled substance transactions and inventories for itself and other ARCOS registrants within its corporate structure.

Non-registered Central Reporter

A non-registered central reporter neither manufactures nor distributes controlled substances, does not have a DEA registration, and does not have controlled substance transactions or inventories, but reports the controlled substance transactions and inventories of the ARCOS registrants within its corporate structure.

Note: The reporting frequency must be the same for a central reporter and all of its subsidiaries.
