How do I verify a VIN matches the title before buying?
Compare the title VIN against the dash plate (under the windshield), the door-jamb sticker, and — for drivetrain parts — the engine block stamp. All four should match. Run the VIN through the free NHTSA vPIC decoder (vpic.nhtsa.dot.gov) and the NICB Vincheck stolen-vehicle lookup before paying.
VIN tampering is the single biggest fraud risk in salvage sales. A mismatched or removed VIN is a federal felony under 18 U.S.C. § 511 and § 2321.
Step 1: Locate every VIN on the vehicle. US vehicles built after 1981 carry a 17-character VIN in at least three places: the dash plate (visible through the windshield, driver side), the driver-side door jamb sticker, and stamped on the engine block or firewall. Trucks may have additional stamps on the frame rail.
Step 2: Compare each VIN to the title. All characters must match exactly. A single transposed digit is a red flag. If the dash plate looks tampered (rivets replaced, plate sitting unevenly, paint pooled at edges), walk away.
Step 3: Decode the VIN. Plug the VIN into the NHTSA vPIC API or vincheck.nhtsa.dot.gov to confirm year, make, model, body type, and engine. Mismatched specs mean either a fraudulent VIN or a swap that was never re-titled — both are problems.
Step 4: Check the title brand history. Each state DMV offers a title-history search (often free). NICB Vincheck (vincheck.nicb.org) shows whether the VIN was reported stolen or as a salvage total loss.
If you are buying a part — engine, transmission, ECU — confirm the donor VIN is documented on the listing and matches the seller's title. BustnFound's part listings include the donor VIN field for exactly this reason.
Frequently asked
Is the NHTSA VIN decoder free?
Yes. The vPIC API at vpic.nhtsa.dot.gov is fully free and unlimited. BustnFound uses it for our VIN decoder and so does the rest of the industry.
Can I check if a VIN was reported stolen?
Yes, free at vincheck.nicb.org. The National Insurance Crime Bureau database covers most major insurers and updates roughly weekly. Coverage is not 100%, so cross-check with state DMV records too.
What if the engine VIN doesn't match the title?
An engine swap is legal in most states but should be disclosed and re-stamped per state DMV process. Undisclosed or unstamped swaps can prevent registration. Ask the seller for documentation; if there is none, do not buy.
