Check a used vehicle's title brand and odometer history against the federal NMVTIS database through an AAMVA-approved data provider

Steps

1. Recognize that NMVTIS itself is not a public API you can call directly — it's a federally mandated (DOJ-overseen, AAMVA-operated) title database that must be accessed through an AAMVA-Approved NMVTIS Data Provider.
2. Choose an approved provider that offers programmatic access (e.g., Vitu, ClearVin, VinAudit, Auto Data Direct) rather than only a consumer web form, since API/batch access is a provider-specific offering, not a NMVTIS-wide feature.
3. Submit a VIN through the chosen provider's API to retrieve the NMVTIS-sourced fields: title issuance history and state, brands (salvage, flood, junk, odometer rollback, etc.), and total-loss history reported by participating insurers/junk-salvage yards.
4. Cross-reference the NMVTIS brand data against a separate marketing-branded vehicle history report (e.g., Carfax/AutoCheck) if your workflow needs both, since NMVTIS is the authoritative minimum federal dataset those commercial reports also draw from, but is not a full replacement for their broader record aggregation.
5. If you intend to become an approved data provider yourself rather than reselling through one, budget for AAMVA's structured testing/certification process and the associated development fee before going live.
