Romanian Identity Card - CNP

CNP

The card contains the individual's Cod Numeric Personal (CNP), or Personal Numeric Code, a unique identifying number.

The CNP consist of 13 digits as follows:

• 1 digit for sex and century of birth: 1, 3, and 5 = male; 2, 4, and 6 = female. 1 and 2 = 20th century, 3 and 4 = 19th century, and 5 and 6 = 21st century. (For legal residents the numbers 7 and 8 are used to encode the sex of the person having the residence permit);
• 6 digits for birth date in the format YYMMDD
• 2 digits for place of birth (the code for the county) (For legal residents the numbers encode the region where the person having the residence permit comes from);
• 3 other digits
• 1 control digit

The CNP is unique for each person. It is assigned at birth and never changes except in cases of erroneous attribution, sex change or change of status from legal resident to citizen.
