PIS/PASEP Generator

What is a PIS/PASEP generator used for?

Both PIS (Social Integration Program) and PASEP (Public Servant Heritage Formation Program) are 11-digit registrations that identify workers. To test HR forms and systems, developers need valid numbers.

The numbers generated here respect the official check-digit algorithm, so they are mathematically correct. But they are fictitious and correspond to no real person.

For testing and development use only.

Understanding PIS / PASEP / NIT / NIS

In Brazil, a single 11-digit number tracks a worker's relationship with the federal social-security system across four different acronyms. They all share the same structure and check-digit algorithm — only the registration channel changes. The number is permanent: once assigned, the worker keeps it for life across job changes, retirement and social programs.

• PIS — Programa de Integração Social. Created by Complementary Law 7/1970 for private-sector employees. Funds the abono salarial (annual minimum-wage bonus) and is administered by Caixa Econômica Federal.
• PASEP — Programa de Formação do Patrimônio do Servidor Público. Created by LC 8/1970 for public servants, administered by Banco do Brasil. PIS and PASEP were merged into the PIS/PASEP fund in 1976 and effectively work as one identifier today.
• NIT — Número de Inscrição do Trabalhador. Used by self-employed people and individual contributors (contribuinte individual) who pay INSS directly. Issued by the INSS through the Meu INSS app or website.
• NIS — Número de Identificação Social. Issued by Caixa via the CadÚnico registry; the entry key for federal benefits such as Bolsa Família, BPC and Auxílio Brasil.

Structure and check-digit math

The number has 11 digits: 10 identifiers plus 1 check digit (DV), usually printed as XXX.XXXXX.XX-D. The DV is computed with modulo 11 using descending weights:

digits  d1 d2 d3 d4 d5 d6 d7 d8 d9 d10
weights  3  2  9  8  7  6  5  4  3  2

sum = Σ (digit_i × weight_i)
rest = sum mod 11
DV   = 11 − rest   (if DV ≥ 10, DV = 0)

Where it shows up

Brazilian employers must report the PIS/PASEP of each worker to eSocial (the unified payroll/HR e-filing system), to FGTS deposits (the severance fund), to the RAIS annual report and to the abono salarial payment list. Workers can look up their number on the Meu INSS app, on the CTPS Digital (digital employment booklet), on the Caixa Trabalhador app or on old paper documents like the orange PIS card.

FAQ

Are PIS and PASEP the same thing today? Practically yes. The funds were merged in 1976 and both numbers follow the same format and algorithm. The label differs only by who issued it: Caixa (private sector) or Banco do Brasil (public sector).

Can I have two PIS numbers? No. Duplicate registrations are a federal irregularity (duplicidade de cadastro) and must be merged by the INSS — failure to do so can block the abono salarial and FGTS withdrawals.

I'm self-employed — do I need PIS or NIT? NIT. The PIS is issued automatically on your first formal employment. If you start as a freelancer, register for an NIT on Meu INSS so your INSS contributions count toward retirement.

Can I use these generated numbers to claim benefits? No. They satisfy the modulo-11 check but are not registered with the INSS or Caixa. Use them only for unit tests, mock data and form-validation development. Submitting a generated number to a real benefit is identity fraud.
