VIN Decoder: Check a Vehicle VIN Number

Use this VIN decoder to read a 17-character Vehicle Identification Number without sending it anywhere. It checks the length and the letters, calculates the check digit, and breaks the VIN into its parts: the World Manufacturer Identifier, the vehicle descriptor, the model year code, the plant code and the serial number. It also shows the country of origin and the manufacturer for common makers. It does not look up specs, owners or accident history, because those need a database. Because it runs entirely in your browser, the VIN never leaves your device.

Frequently asked questions

What does a VIN tell you?

A VIN identifies the maker, the country of assembly, the model year and the build serial. Positions 4 to 8 describe the vehicle, position 9 is a check digit and positions 12 to 17 are the serial number.

Why are I, O and Q not allowed in a VIN?

They look too much like the numbers 1 and 0, so the standard leaves them out to avoid reading mistakes.

What is the check digit?

Position 9 is calculated from the other 16 characters using a weighted formula. North American vehicles must have a correct one, so it catches typing errors and many fake VINs.

Can this show the vehicle specs or history?

No. This decoder works offline and reads only the structure of the VIN. Engine, trim and history come from databases that are not part of this tool.

How is the model year found?

Position 10 holds a year code. A letter or digit repeats every 30 years, and on North American vehicles position 7 tells which cycle: a letter means 2010 to 2039 and a digit means 1980 to 2009.
