How Do You Check a Used Car's Title History Before Buying?
Why the history check comes first
Of all the diligence steps in a used-car purchase, the title-history check is the cheapest relative to what it can save you. Before you drive across the state to see a car, before you pay a mechanic to inspect it, a few minutes with the VIN can tell you whether the car has a salvage brand, a title washed through another state, or an odometer discrepancy — any of which changes the conversation entirely.
What NMVTIS is
The National Motor Vehicle Title Information System (NMVTIS) is the official U.S. system for title histories, operated under the Department of Justice at vehiclehistory.bja.ojp.gov. States, insurers, and salvage businesses are required to report into it, which is what makes it different from purely commercial history products: it's the system designed specifically to stop title fraud — including "title washing," where a branded title is re-registered in another state to hide the brand.
An NMVTIS report, obtained through one of the approved providers listed on the official site, covers:
- Current title state and title brands — salvage, junk, flood, rebuilt.
- Odometer readings reported at title events, which is how rollbacks get caught.
- Total-loss and salvage records from insurers and salvage yards.
What it doesn't cover
No history report — NMVTIS or commercial — sees everything. Repairs paid out of pocket, accidents never reported to an insurer, and mechanical wear leave no trace in any database. A clean report means no recorded problems, not no problems. That's why the history check complements, and never replaces, a physical inspection and an independent mechanic's once-over. The FTC's used-car guidance makes the same point: history reports and inspections do different jobs, and a careful buyer uses both.
Reading the results against the paperwork
The real value comes from cross-checking. Lay the report alongside the title certificate and, at a dealership, the window disclosures:
- The title state on the report should match the title in the seller's hand. A car titled in Maine whose report shows a recent title event in a distant state deserves an explanation.
- The odometer trail should climb steadily and end below the dashboard reading. A number that goes down, or a dashboard reading below the last recorded event, is a serious red flag.
- Brands on the report should match what the seller disclosed. A rebuilt-title car can be a legitimate purchase at the right price — an undisclosed rebuilt title is a different matter, and in Maine the title itself should carry the brand, as covered in our title transfer guide.
When to walk away vs. ask more questions
A branded title, disclosed up front and priced accordingly, is a judgment call. An odometer discrepancy, a title not in the seller's name, or a seller who discourages you from running the VIN at all — those are the situations where the best move is simply to keep shopping. There are always more used cars than there are honest explanations for bad paperwork.
