A DEA number consists of two letters and how many numbers that are assigned to a specific physician?

Three numbers
Five numbers
Seven numbers
Nine numbers


Seven numbers

Rationale: There are two letters and seven numbers in a DEA number. Each physician (or prescriber of controlled substances) has a unique DEA number. In the new DEA number series (for most practitioners), the letter "G" begins the DEA number. Previously, the letters A, B, and F began DEA numbers. The letter M is used for mid-level practitioners. The letters P and R are used for manufacturers, distributors, researchers, etc.
