How to Read a CARFAX Report

A vehicle history report compiles records from insurers, DMVs, auctions, and service shops into one timeline. Knowing what each section means helps you actually use the report instead of just glancing at a pass/fail summary.

Title history

This section shows whether the title has ever been branded — salvage, rebuilt, flood, or lemon — in any state the car has been registered in. A clean title history across every state is one of the most important things to confirm before buying.

Accident and damage records

This lists any reported accidents or insurance claims, when available. Keep in mind this section only reflects what's been reported to data sources the report pulls from — an accident that was never reported to insurance or police may not appear, which is why an in-person inspection still matters even with a clean report.

Odometer readings

A timeline of recorded mileage readings from title transfers, inspections, and service visits. Look for mileage that increases steadily and logically over time — a reading that's lower than a previous one, or an unusual gap, can indicate odometer fraud or a data error worth investigating further.

Ownership history

Shows the number of previous owners and roughly how long each held the car. Fewer owners generally suggests more consistent care, though this isn't a hard rule — a well-documented multi-owner car can still be in excellent condition.

Service and maintenance records

Some reports include service history from shops that report to the data provider, though this is often incomplete — plenty of legitimate maintenance never gets reported. Treat this section as a bonus data point, not the full picture, and still ask the seller for their own records directly.

What a clean report doesn't guarantee

A clean history report reduces risk but doesn't replace an in-person inspection or test drive — it can't tell you about current mechanical condition, and it only reflects what's actually been reported to its data sources.
