Common questions
Will these pass my validation?
Yes — they are well-formed Aadhaar Number values (NNNN NNNN NNNN) and pass standard format checks, including the Verhoeff 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.
