Look up your Hummer

Example — from a real report

Descriptions use Hummer's factory terminology. A typical report lists 60–150 codes.

Buying a used Hummer

Verify the spec in the advert against the factory record — original paint, factory options, and whether the advertised package is genuine.

Selling with confidence

A documented factory spec supports your asking price — desirable factory options are worth showing, not claiming.

Restoration & parts

Order the right parts first time and return a project car to its exact original specification, down to the trim code.

Insurance & valuation

Agreed-value policies and specialist valuations often ask for proof of factory options — the build sheet is that proof.

Which Hummer models are covered?

Factory build data is available for H1, H2 and H3, among others. Coverage varies by model year and delivery market — the free preview confirms availability for your exact VIN before you pay.

Does it cover all Hummer generations?

Coverage spans H1, H2 and H3, though availability varies by model year. The free preview lookup confirms coverage for your exact VIN before you pay — you’re never charged for an unsupported vehicle.

What are RPO codes?

Regular Production Option (RPO) codes are General Motors’ factory option identifiers. Your build sheet lists every RPO recorded against your VIN with its factory description.

Do I need the VIN, or will the UK reg work?

Either works. For UK-registered cars the reg is enough — we resolve the VIN automatically. For imports or unregistered vehicles, use the 17-character VIN.

Is service history available for Hummer?

Not currently — the Service History add-on covers selected manufacturers only. For Hummer, the Factory Specification PDF is available on its own. See pricing for details.

Where does the data come from?

Directly from official manufacturer build records, keyed to your VIN — the same data a franchised Hummer dealer sees. It can't be edited by a seller and doesn't rely on paperwork surviving.
