How many digits does a PIS/PASEP number have?

11 digits: 10 base digits and 1 check digit. With punctuation, it is written as 000.00000.00-0.

How does the tool calculate the check digit?

With Modulo 11, using the weights 3, 2, 9, 8, 7, 6, 5, 4, 3 and 2 on the first 10 digits. The check digit is 11 minus the remainder of the sum divided by 11, and becomes 0 when that result is 10 or 11.

Can the generated number be used as a NIS or NIT?

Yes, for testing. PIS, PASEP, NIS and NIT use the same 11-digit format and the same check digit rule, so a system that validates one of them accepts the others.

Does the generated number belong to someone?

The tool doesn't query any database. The numbers are drawn at random and only follow the check digit rule, so one of them may match someone's real number by chance. Use them for testing only.

Can I look up my own PIS here?

No. The validator on this page only checks the check digit. To look up your own PIS, PASEP or NIS, use the official channels: the Carteira de Trabalho Digital app, Meu INSS, Caixa or Banco do Brasil.

About the PIS/PASEP number

What is PIS/PASEP?

PIS (Programa de Integração Social) is the registration number of private-sector workers in Brazil and is managed by Caixa. PASEP (Programa de Formação do Patrimônio do Servidor Público) is its equivalent for public servants, managed by Banco do Brasil. Both use the same number format, which is common in payroll and HR systems.

Are PIS, PASEP, NIS and NIT the same number?

They have the same format. NIS (Número de Identificação Social) is used by social programs and NIT (Número de Identificação do Trabalhador) by INSS, Brazil's social security institute. All of them have 11 digits and the same check digit rule, so a number generated here works for testing any of these fields.

How is the check digit calculated?

Each of the first 10 digits is multiplied by its weight, in the order 3, 2, 9, 8, 7, 6, 5, 4, 3 and 2. The results are added up and divided by 11: the check digit is 11 minus the remainder. If that gives 10 or 11, the check digit is 0. With punctuation, the number is written as 000.00000.00-0.
