Vehicle history report by VIN
A vehicle history report compiles a car's recorded past by VIN — accidents, title brands, salvage, odometer, theft, and ownership — into one timeline. Here's what a full report includes, what free checks cover first, and how to read the result.
Free decode from NHTSA data — vehicle details and open recalls. No sign-up.
A vehicle history report is the most complete picture you can get of a used car’s past without taking it apart. Built around the VIN, it gathers events from separate sources — state agencies, insurers, auctions, and federal systems — into a single timeline you can read before you buy.
What a full report includes
- Title and brand history — salvage, rebuilt, flood, junk, and the states where the car has been titled.
- Accident history — reported collisions, with severity and impact where available.
- Total loss and salvage — insurer write-offs and auction damage.
- Odometer readings — mileage logged across events, to expose rollback.
- Theft records — reported stolen and recovery status.
- Ownership and sales history — how many owners and how often it changed hands.
- Open recalls — unrepaired safety recalls from NHTSA.
Our guide to what’s included breaks each record type down in detail.
Free checks come first
Before paying, run the checks that cost nothing. The decoder above returns the vehicle’s specifications and open recalls from NHTSA for free, and the NICB offers a free check for reported theft and certain salvage records. These won’t give you the full history, but they’re fast and can flag a problem before you spend anything. See our take on whether free reports are reliable.
“Free report” often means decoded specs
Which provider to use
Carfax and AutoCheck are the names most buyers encounter, and each is stronger for a different shopper — Carfax for detailed service records, AutoCheck for its auction-oriented score. See our comparison of Carfax vs AutoCheck. Because providers license different data, two reports on the same car can differ, so for a high-stakes purchase some buyers run two.
How to read a report
Confirm the VIN matches the car, then read the title line first — a single brand outweighs a long, tidy history. Weigh accidents by severity, trace the odometer in date order, and check theft and recall status. Then use the report as a checklist against the actual car, and let anything serious drive a pre-purchase inspection. Our step-by-step guide to reading a report walks through each stage.
A report and an inspection are two halves
Common questions
Title and brand history, reported accidents, total-loss and salvage records, odometer readings, theft flags, sales history, and open recalls — assembled from state, insurance, auction, and federal sources.
It varies by provider and format, from single reports to multi-report bundles. Some checks — recalls and a basic VIN decode — are free; the full accident and title history is the paid part.
You can get free pieces — a VIN decode and open recalls here, plus theft data from the NICB — but a complete accident and title history generally requires a paid report. Be cautious of sites advertising a 'free report' that only show decoded specs.
