What Carfax Reports Contain
A Carfax report is a vehicle history document built from records reported to Carfax by insurance companies, repair shops, auto auctions, DMVs, and other sources. When you enter a VIN, Carfax searches its database and returns what it has found about that specific car's past. The report shows accidents, title problems, service records, odometer readings, and ownership changes — but only events that were reported to Carfax.
The report does not tell you everything. Carfax can only report what third parties sent them. A fender-bender fixed at an independent shop with cash, a flood that was never claimed to insurance, or regular maintenance done by the owner themselves will not appear. Carfax itself estimates that about 40% of accident damage goes unreported to them, so a clean report does not mean the car has never been damaged.
You receive a single-page summary at the top, followed by a detailed timeline of reported events. The summary flags major issues in red — salvage titles, flood damage, structural damage — so you can see at a glance whether the car has serious problems.
Key Takeaways
- Carfax reports show accidents, title issues, and service history only when those events were reported to insurance companies, repair shops, or DMVs — not all damage gets reported.
- You can order a Carfax report by entering the VIN on Carfax.com, and most dealerships and many private sellers will provide one for free.
- A clean Carfax report does not may provide the car has never been damaged, because roughly 40% of accident repairs go unreported to Carfax.
- Red flags on a Carfax report — salvage title, flood damage, structural damage — are serious enough to walk away from the car unless you have a mechanic inspect it first.
- Use Carfax alongside a pre-purchase inspection by a trusted mechanic, because the report and the inspection catch different problems.
How to Order a Carfax Report by VIN
Go to Carfax.com and enter the VIN in the search box at the top of the page. Carfax will return a report within seconds. A single report costs money — Carfax charges per report, though the exact price changes. Many dealerships include a free Carfax report with their listing, so check the ad first before you pay.
If you are buying from a private seller, ask them to run the report and share it with you. Many sellers will do this to show the car is clean. If they refuse or say they do not know how, you can run it yourself using the VIN from the title or registration.
Some used-car websites like Autotrader, Cars.com, and Edmunds show a Carfax report summary on their listings at no extra cost. If you see a car listed there, check whether the report is already displayed before you go to Carfax directly.
What Red Flags Mean on a Carfax Report
A salvage title means the car was declared a total loss by an insurance company and then rebuilt and resold. Salvage-title cars are legal to drive in most states, but they are worth significantly less, harder to insure, and harder to resell. If you see a salvage title, have a mechanic inspect the car thoroughly before you buy.
Flood damage and structural damage are the most serious flags. Flood-damaged cars can have hidden electrical and mechanical problems that show up months later. Structural damage means the frame or unibody was bent or cracked, which affects how the car handles and how safe it is in a crash. Both of these are reasons to either walk away or get a pre-purchase inspection from a mechanic who specializes in used cars.
A title branded as "rebuilt" means the car was previously salvage and has since been repaired and re-registered. Like salvage titles, rebuilt titles lower the car's value and resale potential. Multiple ownership changes in a short time can signal a car that has been flipped quickly without repairs, or one that had problems the previous owners did not disclose.
What Carfax Does Not Show
Carfax reports do not include regular maintenance performed by the owner, such as oil changes, tire rotations, or brake pad replacements done at independent shops or by the owner themselves. They also do not show minor accidents that were never reported to insurance — a parking lot fender-bender, a small collision paid for in cash, or damage repaired at a local body shop without an insurance claim will not appear.
Carfax does not inspect the car or verify the accuracy of the information reported to it. If a repair shop or insurance company reports incorrect information, it will appear on the report as fact. You cannot assume that every entry is correct just because it is printed on an official-looking document.
The report also does not tell you about mechanical condition, wear and tear, or whether the car is a good deal for the price. A car with a clean Carfax can still have a failing transmission, worn suspension, or other problems that only a mechanic can find.
Carfax Versus AutoCheck and Other Reports
Carfax is the largest vehicle history provider, but it is not the only one. AutoCheck is another common report, and some dealers use both. The two services pull from different sources and sometimes report different information about the same car. If you see conflicting information between Carfax and AutoCheck, ask the seller which events they can verify with documentation — service records, repair invoices, or insurance paperwork.
Some dealerships and online marketplaces run their own checks or use smaller services. None of these replace a Carfax or AutoCheck report, but they may catch additional information. If you are serious about a car, order both Carfax and AutoCheck to get a fuller picture.
Using Carfax Alongside a Mechanic Inspection
A Carfax report and a pre-purchase inspection by a mechanic serve different purposes. Carfax tells you about the car's documented history — accidents, title problems, and reported service. A mechanic inspection tells you about the car's current condition — whether the engine runs well, whether the brakes are safe, whether there is hidden rust or damage that was never reported.
A car can have a perfect Carfax report and still need thousands of dollars in repairs. Conversely, a car with an accident on its Carfax might have been repaired perfectly and run fine for years. Always have a trusted mechanic inspect any used car before you buy, regardless of what the Carfax report says. The inspection usually costs $100 to $200 and can save you from buying a car with serious problems.
If the Carfax report shows major red flags like salvage title or flood damage, the inspection becomes even more critical. A mechanic can tell you whether the repairs were done properly and whether the car is safe to drive.
Frequently Asked Questions
Can I get a Carfax report for free?
Many dealerships provide free Carfax reports with their listings, and some used-car websites display a summary at no cost. If you buy from a private seller, you can ask them to run it. Otherwise, you pay per report on Carfax.com. The price varies but is typically under $30 for a single report.
What if the Carfax report shows an accident but the car looks fine?
An accident on the report means it was reported to insurance or a repair shop, but it does not tell you how well it was fixed. Have a mechanic inspect the car to check the quality of the repairs, the alignment, and whether there is any hidden damage. Some accidents are minor and repaired perfectly; others cause problems that show up later.
Does a clean Carfax report mean the car has never been in an accident?
No. A clean report means no accidents were reported to Carfax, but many accidents go unreported — especially minor damage paid for in cash or fixed at independent shops. A clean Carfax is a good sign, but it is not a may provide. A mechanic inspection is still necessary.
Should I buy a car with a salvage title if the price is very low?
A salvage title means the car was declared a total loss and rebuilt. These cars are legal to own but are worth less, harder to insure, and harder to resell. Only buy one if you have a mechanic inspect it thoroughly and you understand the risks. The low price reflects the title problem, not necessarily a good deal.
What should I do if the seller's Carfax report and mine show different information?
Carfax updates its database regularly, so reports pulled at different times can show different information. Ask the seller for documentation — service records, repair invoices, insurance paperwork — to verify which events actually happened. If there are major discrepancies, that is a sign to walk away or have a mechanic inspect the car very carefully.
