How to Decode a WMI (World Manufacturer Identifier)

The World Manufacturer Identifier is the first three characters of every VIN. Decoding it tells you where a car was made and by whom.

4 min read · Step-by-step

Key takeaways

  • Characters 1–3 of a VIN are the WMI: region, country, and manufacturer.
  • The first character alone tells you the region — 1, 4, and 5 are the United States.
  • The WMI confirms origin but not history — pair it with a full report.

Step by step

  1. 1

    Isolate the first three characters

    Write out the VIN and separate positions 1, 2, and 3 — that block is the WMI.

  2. 2

    Read the region from character 1

    1, 4, and 5 = United States; 2 = Canada; 3 = Mexico; J = Japan; K = Korea; S–Z = Europe.

  3. 3

    Identify the manufacturer

    Characters 2 and 3 narrow it to a specific maker (for example, 1HG = Honda built in the USA).

  4. 4

    Cross-check the badge

    If the WMI says one manufacturer and the badges say another, treat it as a serious red flag for a cloned VIN.

Frequently asked questions

Can the WMI tell me the model?

No. The WMI only identifies region and manufacturer. Model, body, and engine live in positions 4–8 (the Vehicle Descriptor Section).

Why do some makers have several WMIs?

Large manufacturers use different WMIs per country and plant, so the same brand can start with different three-character codes.
