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 137PH903 and position 10 reads 6. 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
1–3 137 AM GENERAL LLC · World manufacturer identifier
4–8 PH903 Model, body style, engine and restraint system
9 × Check digit — computed per vehicle, not part of the build
10 6 Model year — 2006
11 × Assembly plant
12–17 ×××××× Production sequence number, unique to each vehicle

2006 Hummer H1: specification questions

Is this an original window sticker?

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.

Prices are asking prices from 7 live dealer listings decoded to this build , last updated September 27, 2026 . They are what sellers ask, not what buyers paid.

Vehicle counts come from the 40 VINs of this build we have seen in dealer inventory. They are a sample of the road population, not a production figure.
