Título de Eleitor Validator

About this tool

The Título de Eleitor is a 12-digit number: 8 sequential digits, a 2-digit federative-unit code (01–28), and 2 TSE check digits. The first check digit comes from the sequential digits; the second uses the UF code and the first check digit. The UF code 01 (SP) and 02 (MG) have a special remainder rule. This tool verifies both digits and shows the issuing UF. Technical validation only.

How it works

1. Paste a Título de Eleitor (12 digits).
2. The validator verifies the two TSE check digits and reads the embedded federative-unit code.
3. Read the result — valid or invalid, plus the issuing UF — locally in your browser.

Example output

{
  "valid": true,
  "reason": "Valid voter registration.",
  "Federative unit": "PR (06)"
}

Frequently asked questions

Does a valid voter ID mean it is registered?

No. This only checks the two TSE check digits and the UF code — not whether the voter registration exists.

Is the federative-unit (UF) code checked?

Yes — the UF code feeds the second check digit, and the validator also reports which state it maps to.

Does it run locally?

Yes — validation happens entirely in your browser; the number is never uploaded.
