Classic car VIN decoder

The 17-character VIN arrived with the 1981 model year. A classic from 1981 on — a Fox-body, a C4 Corvette, an E30 — decodes here like any other car. Anything earlier carries a manufacturer's own serial number, five to thirteen characters long, that no federal database decodes. Paste what you have; the page explains what it is either way.

Any length. A 17-character number decodes with NHTSA; a shorter one is a pre-1981 serial and the page explains what it can tell you instead.

Where the number is

1969 and later

A plate at the base of the windshield on the driver's side, readable from outside — federal rule from the 1969 model year. Door-jamb and firewall tags repeat it.

Before 1969

Location is the maker's choice: the driver's door post, the firewall, the frame rail or the cowl. The trim or body tag beside it is a different number that records paint and interior codes.

Match the paper

On a classic, the number on the car and the number on the title must agree character for character. A serial re-stamped, moved or missing is the first thing an appraiser looks for.

What a VIN decode cannot tell you

Source: free federal tools

Everything the decoder shows is what the manufacturer built and filed with the federal government. What happened afterwards — title brands, odometer readings at each transfer, insurance total-loss and salvage records — lives in state DMV records, which reach the public through the federal NMVTIS system. WhichTrim does not sell those reports and takes no commission from anyone who does.

NHTSA's recall lookup covers vehicles from the 17-character era. For a pre-1981 car, recall campaigns exist on paper and in NHTSA's older databases, but there is no VIN lookup.

Recalls for this exact VIN

A decode says what was built. To check whether this vehicle is still unrepaired, NHTSA looks the VIN up against the manufacturer's own campaign list.

Stolen or salvage

The National Insurance Crime Bureau checks a VIN against insurers holding about 92% of US premium. Free, five lookups a day. It sees participating insurers only, never police records.

Title, odometer, total loss

The part that costs money. The Department of Justice publishes the list of providers approved to sell it — buy from that list and compare prices; they all draw on the same federal system.

DOJ approved providers →

Worth knowing before you pay: the Department of Justice states that consumers cannot get an NMVTIS report from Carfax or Experian/AutoCheck — those two supply dealers only. A consumer report from either is built on their own private sources, not on the federal title system, which is why the two can disagree about the same vehicle.

PositionSectionWhat it tells you
1–3World manufacturer identifierWho built it and where. 1, 4 and 5 are the United States, 2 Canada, 3 Mexico, J Japan, K South Korea, W Germany, S the United Kingdom.
4–8Vehicle descriptorModel, body style, restraint system, engine — the section that makes a VIN say which car this is rather than which unit.
9Check digitA checksum of the other sixteen characters. A VIN that fails it has been mistyped or invented.
10Model yearA letter or digit, not the year itself: N is 2022, P 2023, R 2024, S 2025, T 2026. I, O, Q, U and Z are never used.
11Assembly plantThe manufacturer's code for the factory that built this vehicle.
12–17Serial numberThe unit's own sequence number on that line.

Model-year codes, 1980–2030

Source: position 10

The code repeats every thirty years. Position 7 breaks the tie: a letter there means 2010 or later, a digit 2009 or earlier.

Common questions

Source: NHTSA vPIC, 49 CFR Part 565

Can a pre-1981 VIN be decoded?

Not by any federal database. Before the 1981 model year each maker used its own serial format, five to thirteen characters, and the meaning of each position is the maker's. What those numbers usually encode is the assembly plant, the model or series, the engine and the sequential build number — but which character means what depends on the maker and the year, and the authoritative key is the maker's own documentation.

Where is the build record for a classic?

With the maker's heritage or classic division, where one exists — several sell a build sheet or certificate reconstructed from production records against the serial number — and with the marque clubs and registries that have transcribed factory ledgers. WhichTrim links to none of them and takes no commission; search the maker's name with “heritage” or “classic center”.

My classic is from 1981 or later. Does it decode?

Fully. The 17-character standard began with the 1981 model year, so a 1985 Corvette, a 1989 Mustang or a 1991 BMW decodes here from NHTSA's database like any current car — make, model, engine, plant.

What is the model-year letter?

Position 10. A letter or digit that repeats on a thirty-year cycle: B is 1981 and also 2011, Y is 2000 and 2030. Position 7 breaks the tie — a letter there means 2010 or later, a digit means 2009 or earlier. The table on this page lists every year.

Is my VIN stored?

No. The decode runs in your browser against NHTSA's public database. WhichTrim never receives it.
