Fictitious Vehicle Generator

Generate a fictitious Brazilian vehicle with make, model, Mercosul plate, RENAVAM and chassis — for software testing.

For software testing only. The data generated here is random and does not belong to any real person or company. Using it for fraud or in bad faith is a crime.

How to use

  1. Click "Generate" to create a fictitious vehicle with make, model, year, color, fuel type, Mercosul plate, RENAVAM and chassis number.
  2. Each click produces a new vehicle. The RENAVAM has a valid check digit and the plate follows the Mercosul format.
  3. Copy the result. Everything runs in your browser — nothing is stored or sent.

About this tool

Testing a fleet management system, an insurance quoting engine or a vehicle registration form requires vehicle data that passes validation. The RENAVAM needs the correct check digit or the system rejects it. The plate needs to follow the Mercosul format — three letters, one digit, one letter, two digits — or the UI breaks. This generator produces all of that in one click: a real make and model from the Brazilian market, a random year within the last fifteen years, a plausible color, fuel type, Mercosul plate, RENAVAM with valid check digit, and a 17-character chassis number following the VIN exclusion rules.

The makes and models come from the most emplacated brands in Brazil — Fiat, Volkswagen, Chevrolet, Hyundai, Toyota and others — with their actual model names. The plate is random within the Mercosul format. The RENAVAM is computed with the weighted sum and modulo-11 check that DENATRAN uses. The chassis excludes the letters I, O and Q as the VIN standard requires. None of these numbers belong to any real vehicle.

Everything runs locally. The tool is for software testing only. Using generated plates or RENAVAM numbers in real registrations, insurance claims or any official context is fraud.

The formula

RENAVAM check digit: multiply the first 10 digits by weights 3,2,9,8,7,6,5,4,3,2; take (sum × 10) mod 11; if the result is 10, use 0.

Frequently asked questions

Is the plate real?

No. It follows the Mercosul format but is randomly generated and not registered with any DETRAN.

Does the RENAVAM pass validation?

Yes. The check digit is computed with the same algorithm DENATRAN uses, so the number passes any correctly implemented validation.

Does the data leave my browser?

No. Everything is generated locally.

Why Mercosul plates only?

Because the old format (three letters, four digits) was officially replaced. New registrations and re-plating use the Mercosul format nationwide.

Can I use this for insurance quotes?

No. Using fictitious vehicle data in real insurance or registration processes is fraud.
