How to Check a VIN Number: A Step-by-Step Guide

A VIN check is the fastest way to confirm a used car is what the seller claims. Here is exactly how to find, validate, and check any 17-character VIN.

Key takeaways

  • A VIN is 17 characters and never contains the letters I, O, or Q.
  • You can check a VIN in about a minute — the free preview confirms the car identity before you pay.
  • A history report checks title brands, theft, liens, and odometer across all 50 states, not just the one on the title.

Step by step

  1. 1

    Find the VIN

    Look at the lower-left corner of the windshield, the driver-side door jamb sticker, and the title or registration. All three should match.

  2. 2

    Confirm it is valid

    A real VIN is exactly 17 characters and uses no I, O, or Q. If it is shorter, it is likely a pre-1981 vehicle with a different format.

  3. 3

    Enter the VIN for a free preview

    Type the VIN (or a U.S. license plate and state) into the search box to confirm the year, make, and model at no cost.

  4. 4

    Unlock the full history report

    Review title brands, theft records, liens, and odometer readings sourced from NMVTIS, NICB, and state DMVs.

  5. 5

    Compare against the paperwork

    If the report shows a brand or odometer problem the seller did not disclose, you have your answer before spending a dollar more.

Frequently asked questions

Is a VIN check free?

The identity preview — year, make, model, and VIN validation — is free. The full history report (title brands, theft, liens, odometer) is a paid unlock.

What if the VIN is not 17 characters?

Vehicles built before 1981 used shorter, non-standard VINs. Modern U.S. vehicles are always 17 characters; a short or malformed VIN on a newer car is a red flag.

Can I check by license plate instead?

Yes. Enter a U.S. license plate and state and it resolves to the VIN, then pulls the same report.
