What is the correct format for a valid DEA number?

A valid DEA number is structured as two letters followed by seven numbers, which is the correct format for identifying licensed individuals and entities authorized to handle controlled substances.

The first letter signifies the type of registrant. For instance, the letter "A" typically represents physicians, while "B" might indicate hospitals. The second letter is the first letter of the registrant's last name, which helps further identify the individual or organization. The subsequent seven digits are unique numerical identifiers.

This format is designed to help prevent fraud and ensure that the authorities can track the distribution of controlled substances effectively. It is important to recognize that this structure facilitates verification checks, such as the process of calculating a verification digit, which is usually the last digit of the DEA number and is derived from a mathematical formula.

Understanding this format is crucial for pharmacists and other healthcare providers to comply with federal regulations regarding the handling of controlled substances, ensuring that only licensed individuals are authorized to prescribe, dispense, and administer these medications.
