United States Drug Enforcement Administration registration number, two letters then seven digits. The first letter is a registrant type code, A, B, F and G for practitioners and hospitals, M for a mid-level practitioner, P and R for manufacturers and distributors, X for the DATA-Waiver series retired on 29 December 2022 and still present in historical records. The second character is the registrant surname initial, or the digit 9 when they registered under a business name. Excluding the letters the agency never issues cuts false positives, but a part number of the same shape still matches. No collision: in particular the existing us-passport, one letter then eight digits, cannot overlap, because the word boundary forbids starting at the second letter.
