Unique Master Citizen Number (JMBG): what each part means
| 00 | Day of birth. |
|---|---|
| 00 | Month of birth. |
| 000 | Last three digits of the year of birth (e.g. 987 = 1987). |
| 00 | Political region where the number was registered — each former-Yugoslav republic has its own code ranges. Test values use random digits here. |
| 000 | Serial number for people registered in that region on that date; on real numbers 000–499 means male and 500–999 female. Test values use random digits. |
| 0 | MOD-11 check digit over the first twelve digits (weights 7,6,5,4,3,2 repeated); a control value of 10 is not allowed, so such combinations are never issued. |

Common questions
Will these pass my validation?

Could one belong to a real person?
These are synthetic values. They are format-valid but not drawn from a guaranteed reserved range, so use them only for testing.
Can I generate many at once?
Increase the count, or use the free API and CSV/JSON export for large datasets.
For software testing only. These numbers are synthetic and must never be used
for real-world identification, applications, or to impersonate anyone.
