Sozialversicherungsnummer: what each part means
| 000 | Serial number, 100–999 (the first digit is never 0). |
|---|---|
| 0 | Check digit: serial digits weighted 3,7,9 and date digits weighted 5,8,4,2,1,6, summed mod 11. Serials that would need a check of 10 are skipped. |
| 000000 | Date of birth as DDMMYY (a fictitious date is used when the real one is unknown). |
Validation regex

Common questions
Will these pass my validation?
Yes — they are well-formed Sozialversicherungsnummer values (0000 000000) 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.
