Was my car assembled in the US? How PlantCountry works
Free VIN check · US assembly
Free VIN check — was it assembled in the US?
Paste the 17-character VIN. This reads NHTSA PlantCountry. It is a data check, not tax advice, and it does not decide whether any loan is deductible.
People ask “was my car assembled in the US?” because the OBBBA car-loan interest deduction requires final assembly in the United States.
The IRS Working Families Tax Cuts pages say a qualified vehicle must have undergone final assembly in the United States. The IRS also says the location of final assembly is listed on the vehicle information label, and that taxpayers may rely on the vehicle’s plant of manufacture as reported with the VIN, including NHTSA’s VIN Decoder.
AssemblyAlert is a private checker. It is not NHTSA and not the IRS.
How this site scores PlantCountry
Paste a 17-character VIN in the free checker on this page. The server calls NHTSA vPIC and reads `PlantCountry`.
- Pass only if `PlantCountry === UNITED STATES (USA)` exactly
- Canada, Mexico, Germany, and other countries fail
- Puerto Rico is not a pass
- An empty plant country is unknown, not a pass
US-assembly copy stays exact: Passes the US-assembly test / Fails the US-assembly test / Could not determine. The decode report also scores `ModelYear` as a separate new-vehicle signal. An older US-plant car can pass assembly and still fail year / original-use. Plant-country Pass is not the deduction.
The first-character myth
VIN position 1 is a WMI screen only. Characters 1, 4, and 5 are often assigned to the United States, but they are never the verdict. A BMW VIN that starts with 5 (for example 5UX) can still be assembled in Germany.
Do not treat a leading 1 as “US built.” Check plant country.
What a pass does not mean
A pass is one data check. It does not mean the loan is deductible. Used vehicles, leases, business use, loans originated on or before December 31, 2024, MAGI phaseout, and the $10,000 cap are separate IRS gates. See the checklist and calculators. Hang-tags and “American built” lot stickers are not this check — Made in USA sticker myths.
The optional $4 card is a dated vehicle spec sheet (window-sticker style) for a folder, not a government certificate and not an IRS qualification.
