What is an RG Generator?

An RG Generator is a tool that creates mathematically valid RG numbers, useful for testing and developing systems that require this type of documentation.

How does the RG Generator work?

The RG Generator randomly creates the first eight digits and then calculates the check digit using the official validation algorithm (SP standard), ensuring that the generated number passes form and system validations.

The General Registry (RG) or Identity Card is a Brazilian civil identification document that attests to the identity of a citizen, issued by the Public Security Secretariats of the states.

How is the RG formatted?

In the most common standard (like São Paulo's), the RG has 9 characters: eight sequential numbers followed by a check digit. It is generally formatted with dots and a hyphen, like the example: 12.345.678-9.

What is an RG?

The General Registry (RG), also known as an Identity Card, is a national civil identification document in Brazil. It is issued by the Public Security Secretariat (SSP) of each state and is essential for proving a citizen's identity in various situations.

RG Structure and Validation

The RG, especially in the standard adopted by states like São Paulo, consists of 9 characters: 8 numbers followed by a check digit. The check digit can be a number from 0 to 9 or the letter 'X' (which represents the number 10).

For example, the number 123456789 is formatted as 12.345.678-9.

Important Rules:

- The logic for generating and validating the RG may vary slightly from state to state in Brazil. Our tool uses the official algorithm of SSP-SP (São Paulo).

- The check digit ensures that the generated number meets the mathematical rules for document validity.
