Question 1

How do I verify a VIN is real?

Accepted Answer

Two layers: (1) validate the structure — a real VIN is 17 characters, never uses I/O/Q, and its 9th character is a check digit computed from the other 16 (our free validator does this instantly); (2) decode it and confirm the year, make, and model match the physical vehicle, then check the history for theft and title brands.

Question 2

What is the VIN check digit?

Accepted Answer

Position 9 of the VIN. Federal rule 49 CFR §565 requires it to equal a weighted sum of the other 16 characters mod 11 (10 is written as X). If the check digit doesn't compute, at least one character is wrong — a typo, a mis-read 1/I or 0/O, or a forged plate.

Question 3

When does the DMV require a physical VIN verification?

Accepted Answer

Most commonly when titling an out-of-state vehicle, reviving a salvage title, or fixing paperwork mismatches. A certified inspector (DMV staff, law enforcement, or licensed verifier depending on the state) physically matches the VIN plate to the documents — e.g. Colorado Form DR 2698, California REG 31, Florida HSMV 82042.

Question 4

Can a VIN pass validation and still be stolen or cloned?

Accepted Answer

Yes. The check digit only proves internal consistency. VIN cloning copies a VALID VIN from a legitimate car onto a stolen one — the giveaway is history that doesn't match the vehicle (wrong specs, impossible locations, duplicate registrations). Decode the VIN, compare specs to the car, and run the theft and title history.
