How TrulyCar works
TrulyCar turns a VIN or a US license plate into the car's documented past. This page is the methodology: where each record comes from, what our data access means, what we will never show you, and how the AI features are kept honest.
What TrulyCar is
TrulyCar sells vehicle history reports for US vehicles, one at a time, for $16.99 or less in packs, with no subscription. The free tier decodes any VIN or resolves a plate to a VIN in seconds; the paid report compiles the full record in seconds more and stays in your account. It launched in 2026 and is run by a small team that answers its own support inbox. Two audiences use it: people about to hand over money for a used car, and small dealers screening inventory between auction lanes.
Where every record comes from
A report is only as honest as its sources, and as honest as it is about their limits. Section by section, here is what feeds each part of a TrulyCar report and what it cannot tell you.
| Report section | Source | What it covers | What it cannot |
|---|---|---|---|
| Title & brands | NMVTIS, the federal title system run under the U.S. Department of Justice, and state title records | Title issue dates by state with the odometer reading at each title event, and brands such as salvage, junk, rebuilt, flood, fire, and hail; insurance total-loss and junk-yard records | Say why a brand was applied, or whether a repair was done well |
| Damage & photos | Salvage and wholesale auction archives, plus reported damage events | Auction sales with the photo sets taken at the lane; reported accidents with severity, structural and mechanical flags | Show accidents that were repaired privately and never reported to anyone |
| Odometer | State title events, dealer listings, and auction readings | Every reported mileage reading in date order, with its reporter, and rollback detection when a reading goes backward | Guarantee mileage between readings; a gap is a gap |
| Theft | Active theft databases | Whether the VIN is currently reported stolen, and historical theft records | Confirm a recovery unless it was reported |
| Recalls & specifications | NHTSA, the National Highway Traffic Safety Administration | Open safety recall campaigns for the exact VIN and the manufacturer's build specifications | Know a recall was fixed unless the repair was reported back |
| Maintenance | The manufacturer's published service schedule for the model | Every factory service interval with typical costs, and which of them were due by the last reported mileage | Show whether any of it was done. Shop visits are not reported to any data network we license, so only the seller's receipts can confirm them |
| Market value | Reported market values for the trim, by condition | Trade-in, private party, and dealer retail figures across condition grades | Replace an appraisal of the specific car in front of you |

What our NMVTIS access means, and what it doesn't
TrulyCar is an approved consumer-access provider of NMVTIS, the National Motor Vehicle Title Information System. That means we are authorized to query the federal title database and deliver its title, brand, and total-loss records to consumers, and it is why those records in a report carry the NMVTIS mark. It does not mean the U.S. Department of Justice endorses TrulyCar, reviews our reports, or vouches for any other data in them. States are required by federal law to report into NMVTIS, but participation and timeliness vary, and the system does not contain repair history. The DOJ publishes a plain-language description of what it covers at vehiclehistory.bja.ojp.gov.
What we will never show you
Reports contain vehicle history only. Under the federal Driver's Privacy Protection Act, they never include the names, addresses, or contact details of a vehicle's owners, and we do not offer, and will not build, any product that identifies a person from a plate or a VIN. A license plate lookup on TrulyCar resolves the plate to the car and stops there. This is a legal line, not a product choice, and any service claiming to cross it is either breaking the law or lying about what it can do.
How the AI features are constrained
Two features use a language model, and both are fenced in. TrulyBear's Read, the verdict summary on each paid report, is generated only from that report's records and is then checked by code: any number it states that does not exist in the source data, or any negative verdict without a cited concern, is rejected and the report simply has no summary. Ask TrulyCar, the question box on paid reports, answers from the same records; when it draws on general automotive knowledge instead, the answer is labeled as such, and it may never state a specific price, because the report contains none. Neither feature can invent a record.
How we handle missing data
An empty section means the databases returned nothing for that VIN, and the report says so in those words rather than padding the page. If a source did not respond at all, the report carries a notice naming it. If we cannot compile a report for a VIN you paid for, you are refunded or re-credited automatically, per the refund policy. Absence is information; we would rather show you a gap than fill it.
