Quick answer

A Cadillac VIN is 17 characters. Positions 1–3 say who built it and where, 4–8 describe the body and engine, 9 is a check digit, 10 is the model year, 11 is the plant, and 12–17 are the serial number.

Where Cadillac VINs say the car was built

The first three characters are the World Manufacturer Identifier. Across 422 Cadillac VINs we have on file, these are the codes that actually show up — and the countries behind them:

Model-year codes for the Cadillac

Position 10 carries the model year. Letters skip I, O, Q, U and Z, and the alphabet repeats every 30 years — so a single character can mean two different years. Here are the years this brand was actually built:

When two years share a character, the check digit and serial range tell them apart — that is what the decoder does automatically.

Body and engine characters we see on Cadillac VINs

Positions 4 through 8 describe the build. Manufacturers assign these themselves, so the same letter means different things on different brands. Below — the characters that actually appear on Cadillac VINs in our database:

A character that dominates the column usually marks the body style the model was mostly sold in; a spread across several means multiple bodies or engines shared the same platform.

What a decoded Cadillac VIN gets you

Reading the characters is the easy part. The reason to decode a VIN is what sits behind it:

Where to find the VIN on a Cadillac

Four places carry it, and they should all match. If they don't, walk away from the car.

FIG.06·Cadillac VIN locations
WhereHow to see itWhy it matters
Dashboard, driver sideThrough the windshield, bottom cornerEasiest to check before you touch anything
Driver door jambOpen the door, sticker on the pillarAlso lists tyre pressures and build date
Under the hoodFirewall or strut tower plateSurvives a windshield replacement
Title and insurancePaper documentsMust match the car — a mismatch means fraud or a swapped panel

Frequently asked questions

Is this Cadillac VIN decoder free?

Yes. Decoding is free and there is no signup. You get the year, plant, body and engine characters, plus recall campaigns and owner complaints filed with NHTSA.

How many characters is a Cadillac VIN?

Seventeen, on every Cadillac built from 1981 onwards. Earlier cars used shorter formats that varied by manufacturer.

Why do two model years share the same VIN character?

Position 10 cycles through the alphabet every 30 years, skipping I, O, Q, U and Z. A 1995 and a 2025 car can carry the same letter. The check digit and serial range separate them.

Can a VIN tell me if the car was in an accident?

Not from the characters themselves. The VIN is a key — accident and title history live in separate databases. Our VIN check pulls what is publicly recorded.

What if the VIN on the dashboard doesn't match the door jamb?

Treat it as a red flag. Mismatched plates mean either a replaced panel or a tampered identity. Ask for documents and verify before any money changes hands.
