How the code is structured
An Estonian isikukood is 11 digits: G YYMMDD SSS C
| Position | Meaning |
|---|---|
G | Century & gender: 1/2 = male/female born 1800-1899, 3/4 = 1900-1999, 5/6 = 2000-2099, 7/8 = 2100-2199 |
YYMMDD | Date of birth |
SSS | Serial number that tells apart people born on the same date. Before 2013 it also encoded the hospital of birth |
C | Checksum digit, computed with a weighted mod-11 algorithm over the first 10 digits |
