How is an Ecuadorian cédula validated?

The first two digits must be a valid province (01–24, or 30 for citizens abroad), the third digit must be below 6 for a natural person, and a modulo-10 (Luhn-style) algorithm over the first nine digits must produce the tenth verifier digit using coefficients 2,1,2,1,2,1,2,1,2.

How accurate is this validator?

The modulo-10 algorithm and province rules are exact, so a malformed cédula is caught reliably. A valid result confirms the number is well-formed, not that it is registered with the Registro Civil, which this tool never contacts.

Is my cédula sent anywhere?

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

Ecuador Cédula Validator

Validate an Ecuadorian cédula with the official modulo-10 algorithm.

Ecuador cédula validator

Validate an Ecuadorian cédula de identidad. The 10-digit number encodes a province code (01–24, or 30 for citizens abroad), a type digit, and a final modulo-10 verifier. This tool checks all three rules and reports whether the cédula is valid.

It is privacy-first: nothing leaves your browser. The validator only checks the modulo-10 algorithm and province/type rules — it never confirms the number against the Registro Civil.
