About Romanian CNP (Cod Numeric Personal)
The CNP (Cod Numeric Personal) is the permanent personal identity number assigned to every individual born in or residing in Romania, managed by DEPABD under the Ministry of Internal Affairs.
Composed of exactly 13 digits with the standard format 'S AA LL ZZ JJ NNN C', encoding gender, century, birth date, registration county, daily sequence, and check digit.
Check Digit Calculation Algorithm (Modulo 11)
- Multiply the first 12 digits by weights from constant key [2, 7, 9, 1, 4, 6, 3, 5, 8, 2, 7, 9].
- Sum all 12 weighted products.
- Calculate remainder modulo 11: Remainder = Sum % 11.
- If remainder is 10, check digit is 1; otherwise, check digit equals the remainder.
