Many states provide a searchable license number database on their government website, such as the Massachusetts Division of Professional Licensure, while Drug Enforcement Administration numbers are not available to the general public. Those who need information about a DEA number should contact the state board in charge of licensing.
An active license number indicates that a health care professional can work in the state that issued the license. Some professions that require licenses are physicians, nurses, veterinarians and nutritionists. The Drug Enforcement Administration issues a DEA number that allows the practitioners to write prescriptions of medications. Only health care professionals that have fulfilled their state's requirements and received a license can receive a DEA number.
