Единен граждански номер: what each part means
| 00 | Last two digits of the year of birth. |
|---|---|
| 00 | Month of birth, offset by century: +0 for 1900s births, +20 for 1800s, +40 for 2000s. These test values use the 1900s form. |
| 00 | Day of birth. |
| 000 | Serial number; on real numbers blocks are allocated by region and the last of these digits encodes sex (even = male, odd = female). Test values use random digits. |
| 0 | Weighted MOD-11 check digit (a remainder of 10 becomes 0). |

Common questions
Will these pass my validation?
Yes — they are well-formed Единен граждански номер values (0000000000) and pass standard format checks, including the MOD 11 checksum.
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.
