Request a correction to a CARFAX Report
If you believe that information on a CARFAX Vehicle History Report is inaccurate (e.g. incorrect odometer reading, ownership records, or accident history), you can submit a **Data Research Request**: **Submission Steps:** 1. Go to the **Contact Us** page and select **Report a Concern**. 2. Enter the 17-character VIN and fill in your vehicle details. 3. Under **Correction Type**, select the specific category of the discrepancy (e.g., Odometer, Accident, Title Brand, Ownership, or Other). 4. Explain the issue in detail. 5. **Attach Supporting Documents**: We cannot verify or alter report data without official documentation. Please upload: - DMV Title or registration documents - Police accident reports - Insurance documentation - Official dealership repair or service invoices Once submitted, a Resolution Manager will be assigned to your case, verify the documentation with the reporting entity, and email you a final decision. You can also email supporting documents to **ConsumerResearch@carfax.com** referencing your Case Number.
Why are accident or other details missing?
CARFAX aggregates information from over 139,000 active sources, including police departments, DMVs, auto auctions, and service shops. However, we can only report information that is shared with us. Common reasons why an event (like an accident or service) might not appear on a report: - **Private Repairs**: If a vehicle owner paid for a repair out-of-pocket and did not submit an insurance claim or use a reporting service shop, the repair will not be on file. - **Reporting Timeframes**: Data providers upload records on different schedules (weekly, monthly, or quarterly). A recent event might not have been uploaded yet. - **Non-Reporting Entities**: Some local police agencies or repair facilities do not report data to CARFAX. If you have proof of a missing service event, you can add it manually to your personal dashboard in **CARFAX Car Care** for tracking purposes, though manual entries will not display on public vehicle history reports.
How do I find out the status of my suggested correction?
After you submit a Data Research Request, our Resolution team initiates an investigation with the reporting data source (e.g., a specific DMV, police agency, or service shop). **Investigation Timeline & Updates:** - **Initial Case Email**: You will receive an automated email with your unique Case Number immediately after submitting. - **Research Period**: Most research investigations take **3 to 5 business days** to complete, depending on the response time of the reporting data source. - **Checking Status**: To check on your case, you can reply directly to your case confirmation email. A Resolution Manager will provide updates. - **Resolution**: Once completed, you will receive an email explaining the findings and whether a change has been applied to the CARFAX report.
