DEA number. A DEA number (DEA Registration Number) is a number assigned to a health care provider (such as a medical practitioner, optometrist, pharmacist, dentist, or veterinarian) by the U.S. Drug Enforcement Administration allowing them to write prescriptions for controlled substances.
Under federal law, a DEA number is not technically required to write prescriptions for non-controlled medications such as antibiotics. Although a DEA number is not mandatory for medical providers who do not plan to prescribe controlled substances, practicing without one can cause a lot of headaches. Many insurance companies use a provider's DEA number in processing claims for prescription medications.
