The main providers and what each one reports

The three largest vehicle history report services in the United States are Carfax, AutoCheck, and NHTSA's SaferCar. Carfax and AutoCheck are commercial services that charge per report; SaferCar is free and run by the National Highway Traffic Safety Administration. Each pulls data from different sources, so a car's history may look different depending which service you use.

Carfax draws from insurance claims, police reports, service records, and auction data. AutoCheck uses similar sources but includes data from Copart and IAA, two major salvage auctions. SaferCar focuses on safety recalls, complaints, and investigations — it does not report accident history or service records. If you are checking a used car before purchase, you will likely need information from more than one source.

Smaller services like VinAudit, ClearVin, and EpicVIN also exist and typically cost less per report than Carfax or AutoCheck. These services aggregate data from public records and may include information the larger services miss, but they also may have less complete accident and service history. No single report is may provide to show every incident in a vehicle's past.

Key Takeaways

  • Carfax and AutoCheck are the most widely used commercial services, but they pull from different data sources, so ordering both reports on the same car may reveal different information.
  • SaferCar is free and covers safety recalls and complaints, but does not include accident history or service records.
  • Smaller paid services cost less but may have gaps in their data, particularly for older vehicles or those with limited service history.
  • A vehicle history report shows what was reported to insurers, police, and auctions — not every accident or repair, especially if paid in cash or handled privately.

What each report actually covers

Carfax reports include accident and damage history, title information (salvage, flood, lemon law buyback), service records from participating shops, and ownership count. The report also flags vehicles with multiple owners in a short time or title problems. Carfax data comes from insurance claims, police reports, and repair shops that report to the service — which means accidents that were not reported to insurance or police will not appear.

AutoCheck reports similar categories but emphasize auction history more heavily. If a vehicle was sold at a salvage auction or a dealer auction, AutoCheck typically shows this. AutoCheck also reports title issues and ownership changes. The service includes data from Copart and IAA auctions, which Carfax does not always have access to, so a car that appears clean on Carfax may show auction history on AutoCheck.

SaferCar reports only safety-related information: open and closed recalls, complaints filed with NHTSA by owners, and investigations into safety defects. It does not show accident history, service records, or title status. SaferCar is useful for understanding what safety issues a particular model year has faced, but it tells you nothing about whether this specific car was in an accident.

Cost and where to order reports

Carfax charges per report; a single report typically costs between $20 and $30, though prices vary by retailer. Some dealerships and used car websites (like Autotrader and Cars.com) offer free Carfax reports as part of their listings. AutoCheck costs similarly, usually $20 to $25 per report. SaferCar reports are free and can be ordered directly from NHTSA's SaferCar website using a vehicle's VIN.

You can order Carfax and AutoCheck reports directly from their websites, or through third-party sites like Edmunds, Kelley Blue Book, and many used car marketplaces. Some dealerships will provide a free Carfax report if you ask, particularly if you are seriously considering a purchase. Buying multiple reports on the same vehicle is common practice — many buyers order both Carfax and AutoCheck to compare results.

Smaller services like VinAudit and ClearVin typically cost $10 to $15 per report and are ordered through their own websites. These services are most useful as a second opinion if the major reports show conflicting information or if you want to check a vehicle before paying for a Carfax report.

How to read a report and what gaps to expect

A vehicle history report shows only incidents that were reported to the service's data sources. An accident that was paid for in cash and never reported to insurance will not appear on any commercial report. Similarly, routine maintenance at independent shops, small repairs, or work done by the owner will not show up. A clean report does not mean the car has never been in an accident — it means no accident was reported to insurance, police, or an auction.

When reading a Carfax or AutoCheck report, look for the number of owners, any title issues (salvage, flood, lemon law), accident records with dates and severity, and service history. Cross-reference the ownership timeline with the mileage — if a car has five owners in three years, that is a red flag. If the mileage jumps backward between reports, that suggests odometer fraud. Title issues like "salvage" or "flood" are permanent marks that lower a car's value significantly.

SaferCar reports list recalls by date and status (open or closed). If a recall is listed as open, the car may not have had the repair completed. You can contact a dealership with the recall number to find out whether this specific vehicle was repaired. Complaints on SaferCar are filed by owners and are not verified, so read them as anecdotal rather than definitive.

When to order reports and what to do with them

Order a vehicle history report before you make an offer on a used car, not after. The report should inform your negotiation — a car with accident history or a salvage title should cost less than one with a clean history. If the report shows a major issue (flood damage, salvage title, open recalls), you can use that information to walk away or to negotiate a lower price.

If you are buying from a private seller, you pay for the report yourself. If you are buying from a dealership, ask whether they will provide a free report or whether the price already reflects any known issues. Some dealerships are required by state law to disclose certain title issues, but a report gives you independent verification.

After you own the car, use SaferCar to check for open recalls and have them completed at a dealership. Keep your own service records separate from what appears on the commercial reports — your records are proof of maintenance if you ever sell the car.

Comparing reports from different services

If you order reports from both Carfax and AutoCheck on the same vehicle, you may see different accident histories or title information. This happens because the two services have different data sources and update on different schedules. Neither service is wrong — they are straightforward incomplete in different ways. If one report shows an accident and the other does not, the accident likely happened but was reported to only one of their data sources.

When reports conflict, a pre-purchase inspection by a mechanic becomes more important. A mechanic can look at the car's body panels, frame, and suspension to spot signs of past damage that the reports may have missed. If a report shows an accident but the car looks pristine, the damage may have been minor and well-repaired. If a report is clean but the mechanic finds evidence of frame damage, the accident was never reported to insurance.

For older vehicles (10+ years), history reports become less reliable because older data is less likely to be in the services' databases. A 15-year-old car with a clean Carfax may have had accidents that were straightforward never reported to the service. In these cases, a pre-purchase inspection is your best protection.

Frequently Asked Questions

Can I get a free vehicle history report?

SaferCar reports are free and cover safety recalls and complaints. Carfax and AutoCheck reports cost money, but some dealerships and used car websites offer free Carfax reports as part of their listings. Smaller services like VinAudit offer cheaper reports ($10–$15) than the major providers, though they may have less complete data.

What if the report shows an accident but the car looks fine?

Minor accidents are often repaired well and leave no visible damage. A pre-purchase inspection by a mechanic can reveal hidden frame damage, suspension issues, or paint work that indicates past repair. If the report shows an accident and you are concerned, use that information to negotiate a lower price or walk away.

Is a clean history report a may provide the car was never in an accident?

No. A clean report means no accident was reported to insurance, police, or an auction — but accidents paid for in cash or handled privately will not appear. A pre-purchase inspection is the only way to know whether a car has hidden damage.

Should I order both Carfax and AutoCheck?

If you are buying an expensive used car or one with any red flags, ordering both reports is worth the cost. The two services pull from different data sources, so one may show information the other misses. For a routine purchase, a single Carfax report is usually sufficient.

What does a salvage title mean?

A salvage title means the car was declared a total loss by an insurance company and was repaired and resold. Salvage-titled cars are legal to drive but are worth significantly less than comparable cars with clean titles. Some states require a salvage inspection before the title can be cleared.
