You can run a Carfax report using either the 17-character VIN or, in most states, the license plate number — Carfax will cross-reference the plate against DMV records to find the matching VIN automatically. Using the VIN directly is faster and more precise, but the license plate option is useful if you're standing in front of a car without immediate access to the VIN.
Step-by-Step: Checking Carfax by VIN
- Locate the VIN — it's on the lower corner of the windshield (driver's side), the driver's side door jamb sticker, the vehicle title, or registration.
- Go to Carfax.com and enter the VIN into the report lookup field.
- Choose a report package (single report or a multi-report bundle if comparing several vehicles).
- Complete payment and receive the report instantly as a downloadable PDF/web report.
- Review the report for title brands, accident history, ownership count, service records, and mileage consistency.
Step-by-Step: Checking Carfax by License Plate
- Note the plate number and state of registration — both are required since plates are state-specific.
- Go to Carfax's plate lookup tool and enter the plate number and state.
- Carfax matches the plate to a VIN through DMV records.
- Proceed the same way as a VIN search — choose a package, pay, and receive the report.
Note: license plate lookup isn't supported in every state and may occasionally fail to find a match, in which case you'll need the VIN directly.
What You'll Get in the Report
- Title history and brands (salvage, flood, rebuilt, lemon)
- Accident and damage records reported to insurers or police
- Ownership history (number of owners, and sometimes usage type — personal, fleet, rental)
- Service and maintenance records from partnered shops
- Odometer readings at each recorded checkpoint
- Recall information tied to the VIN
Can You Download or Save the Report?
Yes — once purchased, the report is available as a web page and downloadable PDF, and it remains accessible in your Carfax account for future reference.
Limitations to Know Before You Check
- Motorcycles: Carfax's coverage of motorcycles is far more limited than passenger cars, since fewer motorcycle-specific records are integrated into its network.
- Very old vehicles: Reports for cars several decades old may be sparse simply because historical records weren't digitized.
- Recent events: An accident or title change from the last few days may not appear yet due to reporting lag.
- Free VIN checks: Sites offering a "free Carfax check" using only the VIN typically provide a very limited preview (recalls, basic title brand) — the full report still requires payment.
The Bottom Line
Checking Carfax is a quick process either by VIN or license plate, taking only a few minutes end-to-end. For best accuracy, use the VIN directly when possible, and treat the license plate method as a convenient backup when you're evaluating a car in person.
