Does the Peruvian DNI have a check digit?

The 8-digit DNI itself has no official check digit, so only its format can be validated. The verification digit shown is the RENIEC-style modulo-11 figure (weights 3,2,7,6,5,4,3,2) that banks and services append.

How accurate is this validator?

The 8-digit format check is exact and the verification-digit formula is deterministic. A valid format does not prove the DNI is registered with RENIEC, which this tool never contacts.

Is my DNI sent anywhere?

No. The validator is privacy-first — all processing happens locally in your browser and the DNI never leaves your device.

Peru DNI Validator

Format-check a Peruvian DNI and compute its RENIEC verification digit.

Peru DNI validator

Validate a Peruvian DNI (Documento Nacional de Identidad). The DNI is an 8-digit serial number; this tool confirms the format and computes the RENIEC-style modulo-11 verification digit (weights 3,2,7,6,5,4,3,2) that banks and online services often require.

It is privacy-first: nothing leaves your browser. The validator checks format and computes the verification digit only — it never confirms the DNI against any registry.
