What Is CARFAX

It is a trusted provider of vehicle history reports for used cars in the United States and Canada. A CARFAX report compiles detailed information from thousands of sources, including state agencies, service centers, insurance companies, auctions, and dealerships. This allows buyers to see a complete record of a vehicle’s past.

In short, the report helps buyers avoid hidden problems, and it helps dealerships present verified facts that support their pricing and quality.

Why CARFAX Is Important for Used Car Purchases

Buying a used car can feel uncertain. Many shoppers worry about accidents, odometer fraud, poor maintenance, title issues, or undisclosed damage. A CARFAX report reduces these concerns by revealing the full history of a vehicle.

It is important because it provides the following:

  1. Verified mileage
  2. Ownership history
  3. Accident and damage records
  4. Service and maintenance data
  5. Title information
  6. Recall alerts
  7. Auction and fleet history

Without it, buyers rely only on the seller’s claims. With it, they get facts backed by official data.

What Information Does a CARFAX Report Include?

A standard report includes a wide range of details that help buyers evaluate a vehicle’s past, present, and future condition.

Accident history

It gathers data from police reports, insurance claims, and repair shops. If a vehicle has been in an accident, it will usually appear in the report.

Title information

A CARFAX report confirms whether a car has a clean title or if it has ever been branded. Title brands include salvage, flood damage, rebuilt, or lemon buyback.

Odometer readings

It checks mileage records over time to detect odometer rollbacks.

Service history

It includes maintenance details such as oil changes, brake work, tire rotations, and inspections.

Ownership history

The report reveals the number of previous owners and how long each owner kept the vehicle.

Usage history

This identifies whether the car was used as a rental vehicle, fleet vehicle, taxi, government car, or personal use only.

Recalls

It alerts buyers if the vehicle has any outstanding manufacturer recalls.

Emissions results

Depending on the state, it will include emissions test results.

This level of detail makes CARFAX one of the most valuable tools for evaluating a used vehicle.
