Beginning Jan. 1, 2017, the Drug Enforcement Administration (DEA) will no longer send its second renewal notification to DEA registrants by mail; an electronic reminder will be sent via email. If a registration expires, registrants will have one calendar month to reapply; after that timeframe, registrants must file for a new DEA registration.
Regardless of whether a registration is reinstated within the calendar month after expiration, federal law prohibits the handling of controlled substances or List 1 chemicals for any period of time under an expired registration.
The DEA notice about the changes is available on its website.
