ChassIQ Help

Find, document, and understand any collector vehicle. This is where to learn how to search records, submit a car, add photos and links, and read a vehicle's provenance — and what the identifiers and scores mean.

Start here

• Using ChassIQ — search, submit a vehicle, attach photos and links, read a record, and manage your account.
• Key Concepts — the vocabulary behind records: GVI, depth, status tiers, provenance.
• What is ChassIQ? — the bigger picture.

Find what you need

• The Global Vehicle Identifier — the permanent ID that ties a car's records together across VINs, plates, and chassis numbers.
• Where the data comes from — government registries, OEM factory data, auction results, and community contributions.
• Coverage by region — what's supported in North America, the UK, Europe, Japan, and Australia/NZ.
