Common questions

Will these pass my validation?

Yes — they are well-formed Isikukood values (00000000000) 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.
