What does each part of a VIN mean?

A 17-character VIN follows the ISO 3779 standard, which divides the string into three sections.

Positions 1-3 — World Manufacturer Identifier (WMI)
Identifies the manufacturer. The first character also indicates the geographic region of origin: 1, 4, 5 = United States, 2 = Canada, 3 = Mexico, J = Japan, K = South Korea, W = Germany, Z = Italy.
Positions 4-9 — Vehicle Descriptor Section (VDS)
Manufacturer-specific encoding of the model, body style, engine and restraint system. Position 9 is the check digit on US- and China-spec VINs — a calculated value used to verify the VIN hasn’t been tampered with or mistyped.
Position 10 — Model year
A single character that cycles every 30 years: A=1980 or 2010, B=1981 or 2011, and so on. The newer interpretation applies if position 7 is alphabetic; the older if position 7 is numeric. The letters I, O, Q, U and Z are skipped.
Position 11 — Plant code
A manufacturer-assigned single character identifying the assembly plant. Each manufacturer maintains its own plant code table.
Positions 12-17 — Production sequence number
The unique production serial number for that vehicle within its model year. Sequential within plant.

Looking for auction history?

The decoder above tells you what the VIN encodes structurally. To see if the same VIN was sold at a Copart, IAA, Manheim or other auction — with photos, sale price, condition and damage details — use our auction history search.
