How the result is calculated
The two modulus-11 calculations detect common transcription errors. A pass does not query Receita Federal or confirm a person, registration or tax status.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
Important limitations
Results are provided for convenience and should be checked independently before an important decision. A format or checksum result never authenticates an identity, document, account, licence, vehicle or registration.
