The DEA number is required for prescribers and manufacturers handling controlled substances and is used to verify their identity and track drug distribution. The number consists of a letter indicating the year a license was obtained, the initial of the prescriber's last name, and randomly generated numbers. While commercial bottles may display a C and license number, patient bottles must include a statement prohibiting transfer of the drug to anyone other than the intended patient.
