CARFAX vs AutoCheck: differences that matter when buying
CARFAX and AutoCheck are the two best-known US vehicle history brands. They overlap a lot, but they are built differently and can show different records for the same car. Here is how to choose, and where the VinCode report fits.
The short answer
Neither report is complete on its own. Both rely on records that DMVs, insurers, auctions, police, dealers and repair shops choose to report. CARFAX is known for detailed service and maintenance entries from dealers and shops. AutoCheck, owned by the credit bureau Experian, is known for its auction data and its AutoCheck Score, which compares a vehicle with similar vehicles of the same class and age.

Which one should you use?
Buying from a dealer
Ask for the report the dealer already has. Many dealers provide one free with each listing. Read the full report, match the VIN and check the report date.
Buying privately
Private sellers rarely include a report, and this is where title washing and odometer fraud are most common. Run your own report and compare it with the title and the seller’s story.
Buying an auction or ex-fleet car
Auction history, total-loss records and commercial use matter most. Look for salvage brands, insurer ownership and auction sales soon after storm dates.
Where VinCode fits
The VinCode report puts title brands, accidents, total-loss events, odometer readings, owners and service records on one page, adds the VinCode Score with every deduction explained, and costs $5.99 for one VIN with a free availability check first. See the sample report.

Decoding shows how it was built. The report shows what happened to it.
Title brands, accidents, total-loss events, odometer readings, owners and service records for the VIN, scored with the VinCode Score.
Neither is better for every car. They draw on overlapping but different sources, so one can show a record the other misses. Read whichever report you get in full.
Why do CARFAX and AutoCheck show different things?
Each company has its own data agreements with DMVs, insurers, auctions and service shops, so the records reported to each can differ.
Is a VinCode report the same as CARFAX or AutoCheck?
No. VinCode is an independent report with its own layout and the VinCode Score.
Do I need both reports?
For a high-value car or a car with gaps in its history, two independent sources can help. For most buyers, one full report plus an inspection is enough.
