Structure of the national ID number
- The national ID number consists of 11 digits
- The first six digits represent the date of birth in the order date, month, year
- The next three digits are an individual number, the third digit of which indicates gender – even numbers for women and odd numbers for men
- The last two digits are control digits
- The last five digits of the national ID number constitute the personal number
- The three digits comprising the individual number are allocated sequentially within the specific date of birth. Individual digits are allocated as follows:
- born 1854-1899: allocated from series 749-500
- born 1900-1999: allocated from series 499-000
- born 1940-1999: also allocated from series 999-900
- born 2000-2039: allocated from series 999-500
|Day||Month||Year||Individual number||Control digits|
The first digits in the individual number show that the person was born in the 1800s and the last digit indicates a man. This number would belong to a man born on 1 December 1899. For reasons of data privacy, this is not an actual national ID number.
