About this tool
Only the RG issued by SSP-SP (São Paulo) has a widely-documented check digit: the 8 base digits are weighted 2..9, and the mod-11 result gives the 9th character, where a result of 10 is written as 'X'. RGs from other states use issuer-specific formats and often have no verifiable check digit, so this validator is scoped to SP. Technical validation only.
How it works
- Paste a São Paulo (SSP-SP) RG — 8 base digits plus the check character (digit or 'X').
- The validator weights the digits 2..9 and recomputes the mod-11 check character.
- Read the result locally in your browser — nothing is uploaded.
