Overview
CARFAX is a United States-based vehicle-information and automotive-data company whose best-known product is the CARFAX Vehicle History Report. A report is generated from a vehicle identification number, or VIN, and is intended to help buyers, dealers, lenders, insurers, and other automotive participants evaluate a vehicle's recorded history before a purchase or other transaction. Depending on the available records, reports can contain information such as reported accidents or damage, title and registration events, mileage readings, service and maintenance entries, ownership changes, recalls, and use in categories such as rental or fleet service. The exact contents depend on records supplied to or obtained by CARFAX, and a report is not a substitute for an independent mechanical inspection. The business was established in 1984 and developed around the aggregation and presentation of vehicle-history information. Its consumer-facing service allows shoppers to research used vehicles and access reports, while its dealer and automotive-industry services support inventory merchandising, vehicle acquisition, appraisal, pricing, lead generation, and customer communications. The CARFAX brand is also associated with vehicle-history-based labels and marketing tools used by participating dealers and sellers. CARFAX operates primarily in the United States and Canada. Its data ecosystem depends on contributions and integrations from public agencies, motor-vehicle authorities, repair facilities, collision centers, dealerships, auctions, insurers, manufacturers, and other automotive sources. Because reporting practices and source coverage vary, the company presents its information as a record of reported events rather than a complete account of every event in a vehicle's life. CARFAX became part of the R.L. Polk automotive-information business and subsequently came under S&P Global following S&P Global's acquisition of Polk. It is now associated with S&P Global Mobility, the automotive-data segment of S&P Global. As a subsidiary rather than a separately listed company, CARFAX does not have its own public ticker. Its current market role is that of a recognizable consumer and business-to-business data brand within the broader automotive-information industry.
History
CARFAX was established in 1984 in the United States as a business focused on compiling and communicating information about motor vehicles. The company's core concept was to make dispersed records about an individual vehicle more useful by linking them to its vehicle identification number. This approach addressed a longstanding problem in used-car markets: buyers and sellers often had unequal access to information about prior damage, mileage, ownership, maintenance, title status, and vehicle use. Over time, CARFAX developed the vehicle-history report into a consumer-recognized product while also building services for professional automotive users. Dealers could use reports and related data in acquisition, appraisal, inventory presentation, and sales processes; consumers could use them as one input when comparing used vehicles. The company's information model relies on records from multiple sources, including motor-vehicle agencies, repair and service businesses, collision facilities, dealerships, auctions, insurers, and other participants in the automotive ecosystem. Since source coverage is not uniform, CARFAX reports document reported information rather than guaranteeing that every past event has been captured. The company later became part of the R.L. Polk automotive-information business. S&P Global acquired R.L. Polk in 2013, bringing CARFAX into the S&P Global portfolio. CARFAX subsequently operated within the automotive-information activities now associated with S&P Global Mobility. This ownership structure gave the brand a place within a larger provider of data, analytics, and workflow products for automotive markets while preserving CARFAX as a distinct consumer-facing name. In its current form, CARFAX serves both individual vehicle shoppers and professional automotive organizations. Its public-facing services support used-car search and vehicle-history research, while business offerings are designed to help dealers and other industry users manage inventory, communicate vehicle condition and history, and make transaction-related decisions. The brand's central proposition remains the same: make available vehicle records easier to understand so that users can make more informed decisions. CARFAX remains active in the United States and Canada and is a subsidiary rather than an independently listed public company.

Products and positioning
CARFAX positions itself as a trusted source of vehicle-history information that helps people shop, buy, own, service, and sell used cars with greater confidence. Its differentiation rests on a widely recognized consumer brand, a large network of automotive and public-record data sources, and distribution through dealers and other industry participants.
