JM1
Mazda passenger cars built in Japan — including every MX-5 Miata
Decode any Mazda VIN free — CX-5, Mazda3, CX-50, MX-5 Miata, and more — for the factory trim, engine, plant, and open recalls.
Factory build data from manufacturer and government sources
The first three characters (the WMI) identify the manufacturer and where the vehicle was built. Common Mazda prefixes:
Mazda passenger cars built in Japan — including every MX-5 Miata
Mazda SUVs built in Japan
Mazda vehicles built in Mexico — Mazda3
Mazda SUVs built in Alabama — CX-50
Every Miata ever made is Japan-built (JM1); the CX-50 comes from the Mazda-Toyota joint plant in Alabama (7MM); many Mazda3s are Mexico-built (3MZ).
Mazda paint codes are three characters — 41V Soul Red Crystal, 46G Machine Gray — on the door jamb label.

Driver-side door jamb label (also carries the paint code)
