What Autocheck tells you from a VIN
Autocheck is a vehicle history report service owned by Experian that pulls data from auctions, insurance companies, DMVs, and repair shops to build a record of a specific car. When you enter a VIN, Autocheck returns information about title transfers, accident history, mileage records, service records from some shops, and whether the car has been branded with a salvage or flood title.
The report does not tell you everything about a car's past. Autocheck only includes accidents that were reported to insurance companies or that went through auctions. A fender-bender fixed at a local body shop with cash will not appear. Similarly, Autocheck cannot see routine maintenance done at independent mechanics — only records from some national chains and dealerships show up.
The service costs money per report, though prices vary depending on whether you buy single reports or a subscription. You can order a report directly from Autocheck's website, or through many used-car listing sites like CarGurus and Edmunds, which sometimes bundle a free or discounted report with a listing.
Key Takeaways
- Autocheck pulls accident, title, and mileage data from insurance companies, auctions, and DMVs, but misses repairs done outside major chains and dealerships.
- The report flags salvage titles, flood damage, and odometer rollback patterns, which are the most important red flags when buying used.
- Autocheck costs between $20 and $30 per single report, though some used-car sites offer discounted or bundled access.
- A clean Autocheck report does not may provide a car is safe or reliable — you still need a pre-purchase inspection by a mechanic.
- Autocheck and Carfax are the two main history report services; they sometimes show different information because they use different data sources.
What shows up on an Autocheck report
An Autocheck report displays a timeline of major events in the car's history. At the top, you see the title status — whether it is clean, salvage, flood, lemon law buyback, or branded for another reason. Below that is a list of reported accidents, with dates and whether they were minor or major. The report also shows mileage readings from various points in time, which helps you spot odometer fraud if the numbers go backward or jump unnaturally.
The report includes ownership history, showing how many previous owners the car has had and whether it was a fleet vehicle, rental, or personal use. Some Autocheck reports pull service records from dealerships and national chains like Firestone and Jiffy Lube, though coverage is spotty and depends on whether that shop reported data to Autocheck.
Autocheck also assigns the car a score from 1 to 100, with higher numbers indicating fewer reported issues. This score is meant as a quick reference, but it should not be your only decision point — a car with a score of 75 might still be reliable, and a car with a score of 85 might have hidden problems that did not get reported.
How Autocheck differs from Carfax
Autocheck and Carfax are the two dominant vehicle history report services, and they often show different information about the same car. The difference comes down to data sources. Autocheck pulls heavily from auction data and insurance claims, while Carfax relies more on DMV records and repair shops. This means Autocheck sometimes catches auction history and insurance claims that Carfax misses, while Carfax sometimes has better repair records from certain regional shops.
Neither service is complete. Both can miss accidents that were not reported to insurance, repairs done at independent shops, or title issues in states with poor DMV reporting. Many buyers order both reports on a car they are seriously considering, since the $40 to $60 combined cost is small compared to the price of a used car.
Autocheck's scoring system (1–100) is different from Carfax's approach, which focuses on flagging specific red flags rather than assigning a single number. Some buyers find Autocheck's score easier to understand at a glance, while others prefer Carfax's more detailed breakdown of individual issues.
Red flags that appear on Autocheck reports
Certain findings on an Autocheck report should make you pause before buying. A salvage title means the car was declared a total loss by an insurance company at some point, even if it was later repaired and resold. A flood title indicates water damage, which can lead to electrical and rust problems years later. A lemon law buyback means the manufacturer took the car back under warranty because of persistent defects.
Odometer rollback is another serious red flag. If the mileage goes backward between two recorded readings, or if there is a large unexplained jump, the car's true mileage is unknown. Multiple ownership changes in a short time can suggest the car had problems that caused each owner to sell quickly. Frequent accident reports, especially if they are recent, suggest the car may have structural damage or ongoing mechanical issues.
A gap in the mileage history — months or years with no recorded readings — is not necessarily a deal-breaker, but it means you have less visibility into how the car was used during that time. Ask the seller directly about gaps and cross-check their story against the timeline on the report.
When to order an Autocheck report
Order an Autocheck report once you have narrowed your search to a specific car you are seriously considering. There is no point running reports on every listing you see — the cost adds up, and the report is only useful for a car you can actually inspect and test-drive. Wait until after you have seen the car in person and confirmed the VIN matches the listing.
Some used-car websites, including CarGurus, Edmunds, and certain dealer sites, offer a free or discounted Autocheck report bundled with the listing. Check whether the listing already includes one before you pay for a separate report. If you are buying from a private seller, you will almost certainly need to order the report yourself.
Get the report before you negotiate price or commit to the purchase. The information in the report should inform your offer and your decision to walk away. If the seller refuses to let you run a history report or seems evasive about the car's past, that is a warning sign on its own.
What an Autocheck report does not tell you
A clean Autocheck report does not mean the car is reliable or safe. The report only shows events that were reported to Autocheck's data sources. A car that was in a minor accident but repaired at a local body shop with cash will show a clean history. A car with a failing transmission that has not yet broken down completely will not appear on the report. Routine maintenance issues, wear and tear, and mechanical problems that have not yet triggered an insurance claim are invisible to Autocheck.
This is why a pre-purchase inspection by a mechanic is essential, even if the Autocheck report looks perfect. A mechanic can spot worn suspension components, fluid leaks, transmission problems, and other issues that no history report can catch. The Autocheck report tells you what happened to the car in the past; the mechanic tells you what condition it is in right now.
Autocheck also cannot verify the seller's claims about maintenance, upgrades, or accident repairs. If a seller says the car has had regular oil changes or a new transmission installed, the report may or may not confirm it depending on where the work was done. Always ask for service records and receipts, and do not rely solely on what the report shows.
How to read an Autocheck report
When you receive your Autocheck report, start at the top with the title status. If it says "Clean," the car has not been branded for salvage, flood, or other major issues. If it shows anything else, read the details carefully and decide whether that status is a deal-breaker for you.
Next, look at the timeline. Read through the accident history in order, noting the dates and severity. Check the mileage readings against each other — they should increase or stay roughly the same over time. If you see mileage go backward, that is a major red flag. Look at the ownership history and note how many owners there have been and how long each one kept the car.
Pay attention to any service records that appear, but do not assume their absence means the car was not maintained. Finally, look at the Autocheck score, but treat it as one data point among many, not as a final judgment. A score of 60 with one major accident five years ago might be less concerning than a score of 75 with three accidents in the last two years.
Frequently Asked Questions
Can I get a free Autocheck report?
Some used-car listing sites like CarGurus and Edmunds include a free or discounted Autocheck report with certain listings. If you are buying from a private seller or a dealer that does not offer one, you will need to pay. Single reports typically cost $20 to $30, though prices vary by how you purchase.
What if the Autocheck report shows an accident but the seller says there was none?
The seller may be mistaken about what counts as an accident, or the report may be picking up a claim that was filed but not paid out. Ask the seller for details and request any repair receipts or insurance paperwork they have. If the story does not add up, have a mechanic inspect the car closely for signs of past damage.
Is an Autocheck report the same as a title check?
No. An Autocheck report includes title information but is broader — it also shows accident history, mileage records, and service data. A title check through your state's DMV only confirms the current title status and ownership. You may want both, especially if you are buying from a private seller in another state.
Should I order Autocheck or Carfax?
Both services have different data sources, so they sometimes show different information. If you are seriously considering a car, ordering both reports costs $40 to $60 total and gives you a more complete picture. If you can only afford one, Autocheck tends to catch auction and insurance data well, while Carfax often has better repair records.
What does an Autocheck score of 50 mean?
Autocheck scores range from 1 to 100, with higher scores indicating fewer reported issues. A score of 50 is below average and suggests the car has some reported problems — accidents, title issues, or other red flags. However, the score alone does not tell you whether the car is worth buying; you need to read the details and have a mechanic inspect it.
