What a vehicle check tells you

A vehicle check is a report that shows the recorded history of a specific car — things like past accidents, title problems, odometer readings, and whether the car has been reported stolen or salvaged. The report pulls data from insurance claims, police reports, DMV records, and auction houses. It does not predict whether a car will break down or how long it will last; it shows what has already happened to that vehicle according to public records.

The most common vehicle check services are Carfax and AutoCheck, though your state's DMV may also offer a title history report. Each service compiles slightly different data sources, so two reports on the same car can show different information. A vehicle check is most useful when you are buying a used car, but you can also run one on a car you already own to see what is in the record.

Key Takeaways

  • A vehicle check report shows accident history, title status, odometer readings, and whether a car has been reported stolen or salvaged, but does not predict future repairs.
  • Carfax and AutoCheck are the two largest private services, and they pull data from different sources, so results may not match between them.
  • Your state's DMV can provide a title history report that shows ownership changes and title brands, which is often free or low-cost.
  • A clean report does not mean a car has never been damaged — it means no insurance claim or police report was filed for that damage.
  • Before buying a used car, run a check through at least one service and compare the results to the seller's story about the car's history.

What information appears in a vehicle check report

A vehicle check report typically includes the vehicle identification number (VIN), make, model, year, and color. It then lists accident and damage records, usually sorted by date. Each entry shows whether the damage was reported to insurance, police, or a salvage yard, and sometimes includes the type of damage (collision, fire, flood) and whether the airbags deployed.

The report also shows title history — how many owners the car has had, whether the title is clean or branded (branded titles indicate salvage, flood, lemon law buyback, or other problems), and odometer readings recorded at each ownership transfer. Some reports flag whether the odometer has rolled backward between readings, which can indicate tampering. Carfax and AutoCheck also note whether the car has been reported stolen, used as a rental or fleet vehicle, or involved in a lemon law case.

What a vehicle check does not show: routine maintenance records, mechanical problems that were not reported to insurance or police, recalls that have not been addressed, or whether the car has been in an accident that the owner paid for out of pocket without filing a claim.

Carfax versus AutoCheck versus your state DMV

Carfax and AutoCheck are the two largest private vehicle history services. Carfax pulls data from insurance companies, police reports, DMV records in participating states, and auto auctions. AutoCheck uses similar sources but also includes data from Copart and IAA, two major salvage auctions. Neither service has access to all accidents or damage — they can only report what was officially recorded somewhere.

Your state's DMV or equivalent agency (called the Secretary of State in some states) maintains its own title history. This report shows ownership transfers, title brands, and sometimes lien information. Many states offer this report for free or a small fee through their online portal or by mail. A DMV title report is often more authoritative than a private service for title status, because it comes directly from the agency that issued the title.

The practical difference: if you are buying a used car, run a check through Carfax or AutoCheck first to see accident and damage history, then request the DMV title report to confirm the title status. If the two reports disagree on title brand or ownership history, the DMV record is the official one.

How to run a vehicle check

To run a vehicle check, you need the vehicle identification number (VIN). The VIN is a 17-character code stamped on the driver's side of the dashboard (visible through the windshield), on the driver's door jamb, and on the title document itself. You can also find it on insurance documents or repair invoices.

For Carfax or AutoCheck, visit their websites directly, enter the VIN, and pay the fee. Carfax charges per report, though bulk packages are cheaper per report if you are shopping for multiple cars. AutoCheck pricing is similar. Some used car dealerships and Kelley Blue Book (KBB) offer free Carfax reports as a sales tool, so if you are looking at a dealership listing, check whether the report is already available before paying.

To get your state's DMV title report, go to your state's DMV website and look for "title history" or "vehicle history" in the public records section. Some states let you order online; others require a form by mail or in person. Have the VIN and the current owner's name ready. Processing time ranges from same-day (for online orders) to two weeks (for mail requests).

What a clean report means and what it does not

A clean vehicle check report means no accidents, damage, title problems, or theft reports appear in the records that the service checked. This is good news — it suggests the car has not been in a major incident that was officially reported. However, a clean report does not mean the car has never been damaged or in an accident.

Many accidents and repairs are never reported to insurance or police. If an owner paid for damage out of pocket, had it fixed at an independent shop, and did not file a claim, that damage will not show up on a vehicle check. Similarly, a car can have mechanical problems, rust, or wear that a report cannot detect. A vehicle check is one piece of information, not a complete picture of the car's condition.

Before buying a used car with a clean report, still have a trusted mechanic inspect it in person. Ask the seller directly about accidents, repairs, and the car's maintenance history. A clean report is reassuring, but it is not a substitute for a pre-purchase inspection.

Title brands and what they mean

A title brand is a label the DMV places on a title to flag that the car has a specific history. Common brands include Salvage (the car was declared a total loss by an insurance company), Rebuilt (a salvage car was repaired and passed inspection), Flood (the car was damaged by flooding), Lemon Law Buyback (the car was returned under a state lemon law), and Branded Title (a catch-all for other issues).

A branded title does not automatically mean the car is unsafe or a bad purchase — a rebuilt salvage car can be perfectly reliable if it was repaired properly. However, a branded title will affect the car's resale value, and some insurance companies charge more to insure a branded-title vehicle or may decline to insure it at all. If you are considering buying a car with a branded title, ask your insurance company whether they will cover it and at what rate before you commit.

The title brand appears on the DMV title report and usually on Carfax and AutoCheck as well. If a vehicle check shows a brand that surprises you, request the DMV title report to confirm, because the DMV record is the official one.

Using a vehicle check when you already own the car

You can run a vehicle check on a car you already own to see what is in the public record about it. This is useful if you are planning to sell the car and want to know what a buyer will see, or if you are curious about the car's history. The process is the same — enter the VIN on Carfax, AutoCheck, or your state DMV website and pay any applicable fee.

If you find an error in the report (for example, an accident that was not yours, or an odometer reading that is wrong), you can dispute it with the service or the source of the data. Carfax and AutoCheck have dispute processes on their websites. If the error is on the DMV title record, contact your state's DMV directly to request a correction.

Frequently Asked Questions

Can I run a vehicle check without the VIN?

No. Carfax, AutoCheck, and DMV title reports all require the VIN to pull the correct vehicle's history. If you do not have the VIN, you can find it on the car's dashboard, door jamb, title, or insurance documents. If you are buying from a private seller and they will not provide the VIN, that is a red flag.

Why do Carfax and AutoCheck show different information?

Carfax and AutoCheck pull data from different sources and update on different schedules. One service may have received a police report or insurance claim that the other has not yet recorded. Neither service has access to all accidents — they can only report what was officially filed. Running both reports gives you a more complete picture, but neither is may provide to be exhaustive.

Does a vehicle check show if a car has been in a minor fender bender?

Only if the owner filed an insurance claim or police report for it. If someone paid for minor damage out of pocket and had it fixed at an independent shop without involving insurance, it will not appear on a vehicle check. This is why a pre-purchase inspection by a mechanic is important — they can spot old repairs that are not in the record.

What should I do if a vehicle check shows an accident I was not involved in?

Contact the service (Carfax or AutoCheck) and file a dispute through their website. Provide documentation showing the accident was not yours — for example, a police report with a different vehicle, or insurance records. You can also contact your state's DMV if the error is on the title record. Corrections can take several weeks.

Is a vehicle check report the same as a title search?

No. A vehicle check report (from Carfax or AutoCheck) shows accident and damage history. A title search shows ownership history and title status. Your state's DMV provides the official title search. You may need both to get a complete picture of a used car's history.
