Most of it is free. Here is the part that is not.

A completely free full history report does not exist, from anyone — NMVTIS title data has a cost floor set by the programme that runs it. What is free is everything else, and that covers most of what rules a car out. This page is the honest split.

Questions about free checks.

Is there such a thing as a completely free vehicle history report?

Not a full one. Title, salvage and odometer records come from NMVTIS, the national system operated by the US Department of Justice, and access to it carries a per-lookup cost set by the programme rather than by any one company. That cost has to be paid by someone. What can genuinely be free is everything outside NMVTIS, and that turns out to be most of what you need to rule a car out: the VIN, the specifications, open recalls, crash ratings and market value.

What can I check on a used car without paying anything?

With Orto: resolve the plate to a VIN, decode the full specification, see every open NHTSA safety recall for that exact vehicle, read its NCAP crash-test ratings, see what comparable cars are selling for nearby, read owner reliability reports, and get an A-to-D Trust Score. You can do that on every car on your shortlist without spending anything.

When is it actually worth paying for a report?

When you have narrowed down to a car you are seriously considering, and the remaining question is what has happened to this specific vehicle rather than to the model. That is the point at which title brands, total-loss records and odometer history matter, and it is the only thing Orto charges for, at $7.99 for a single report.

Why do free VIN checks show so little?

Most free checks are decoding the VIN, which is public information encoded in the number itself, and then stopping at the paywall for anything drawn from title records. The distinction worth keeping in mind is between what the number says about the car as built, which is free everywhere, and what the records say about the car as it is now, which is not.

Does a free check tell me if a car has been in an accident?

Not reliably. Damage only appears in a report if it was reported to a state DMV, an insurer or another NMVTIS reporting entity. Repairs paid for privately leave no record anywhere, in any report from any provider. A free check plus an in-person inspection by a mechanic will tell you more about accident damage than any paid report will on its own.
