AutoCheck
A commercial vehicle history report from Experian; competing with Carfax with a numeric scoring system.
AutoCheck is the vehicle history report service operated by Experian, the consumer credit bureau. It is the most widely-used competitor to Carfax and is integrated into many large-dealer-group software stacks and used-car auction platforms (it’s the default report at most Manheim and ADESA dealer auctions).
AutoCheck’s differentiator is its proprietary AutoCheck Score — a 1–100 numeric summary that condenses the report’s data into a single comparison number, with a percentile-style comparison against vehicles of the same year, make and model. The score is intended to give dealers a quick valuation reference at auction.
AutoCheck’s data sources overlap heavily with Carfax (state DMVs, NMVTIS, auction houses, police reports) but each service has unique partner feeds, so the two reports are not interchangeable. Cautious buyers pull both. Like Carfax, AutoCheck only sees reported events — out-of-pocket repairs at independent shops generally don’t appear.
