Are these PIS/PASEP numbers real?

No. They pass the mod-11 check digit so validators accept them, but they are random and not issued to anyone.

Is PIS the same as PASEP, NIS and NIT?

Yes — they are different names for the same 11-digit identifier and share one check-digit algorithm.

Can I use them in production?

Only for development, testing and QA. They are fictional and must not be used to impersonate anyone.

About this tool

PIS, PASEP, NIS and NIT are names for the same 11-digit worker/social identifier. This tool builds 10 base digits and computes the mod-11 check digit, rejecting trivial repeated sequences. Fictional, valid-format, for technical testing only.

How it works

Choose how many PIS/PASEP numbers to generate and whether to format them.
Optionally set a seed for reproducible output.
Press Generate, then Copy, Download JSON or Download CSV.
