How this VIN pattern is read

A 17-character VIN carries two kinds of information: what was built, and which one it is. This page is the first kind — the nine highlighted positions.

VIN positions 1 through 8 read JM1FC331 and position 10 reads H. Those nine characters define this build. Position 9 and positions 11 through 17 describe the check digit, assembly plant and production sequence; they are not part of this pattern.

Positions Characters What they encode
1–3 JM1 MAZDA MOTOR CORPORATION · World manufacturer identifier
4–8 FC331 Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 H Model year — 1987
11 × Assembly plant
12–17 ×××××× Production sequence number, unique to each vehicle

Useful answers, without the guesswork

1987 Mazda RX-7: specification questions

What engine code is recorded for JM1FC331-H?

The recorded engine model is N3. This is pattern-level data; confirm the installed engine on a vehicle that may have been modified.

Is this an original window sticker?

No. This page summarizes decoded VIN-pattern specifications. An original sticker or build record is needed to verify the optional equipment of a particular car.

Are the known VINs a production total?

No. These are VINs observed in our records. The count does not establish total production or rarity.

Does a missing specification mean the feature is absent?

No. Missing fields mean that a value is not recorded in this decode. Check the individual vehicle and its manufacturer documentation.

Where this data comes from

Specification fields are decoded from the manufacturer's filings in the NHTSA vPIC database, keyed on VIN positions 1–8 and 10. We publish the filed values as they stand and leave out anything the filing does not record.

Vehicle counts come from the 44 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
