Is Carfax Legit? What a Carfax Report Covers, and What It Misses
By CarWhere Research · Updated November 2026
Yes, Carfax is legit. It's a segment of Mobility Global Inc., spun off from S&P Global in July 2026, and its SEC filings cite more than 38 billion history records from 177,000+ sources. A report is worth reading before you buy, but Carfax itself says it “does not have the complete history of every vehicle.” Pair it with an inspection.
Facts below are from each company's own published pages and government sources, checked November 2026. Policies change, so verify the current terms before you act.
Who Carfax is
Carfax runs vehicle history reports, used-car listings and a free maintenance tracker. Since July 1, 2026 it has been one of two reporting segments of Mobility Global Inc., which S&P Global separated in a tax-free spin-off (Form 10-Q). Mobility Global's registration statement gives these figures as of December 31, 2025:
- more than 38 billion vehicle history records from more than 177,000 sources
- more than 92,000 dealers and service shops
- about 23 million average monthly unique visitors
What a Carfax report covers, and what it doesn't
Carfax lists these report sections on its vehicle history reports page. The NMVTIS column shows what the federal title database covers (DOJ).
| Record type | Carfax report | NMVTIS report |
|---|---|---|
| Accidents and damage | Accident history, severity, point of impact, structural damage, airbag deployment | Not included |
| Service history | Oil changes, tire rotations, safety inspections, major replacements | Not included |
| Open recalls | Included | Not included |
| Type of use | Personal, rental, lease, commercial, taxi, police | Not included |
| Owners | Number of previous owners, states, length of ownership | Current title state and last title date |
| Title brands | Flood or lemon title | All reported brands, plus total loss and salvage |
| Odometer | Last reported mileage, rollback check | Odometer readings from titling |
The limit is on Carfax's own page: its reports “are based only on information supplied to CARFAX,” and “CARFAX does not have the complete history of every vehicle.” The FTC adds that a history report “typically” won't list mechanical problems and “is not a substitute for an independent vehicle inspection” (FTC).
Carfax and NMVTIS: a common mix-up
NMVTIS is the federal National Motor Vehicle Title Information System, run under the Justice Department. Its data comes from state titling agencies, insurers, and junk and salvage yards (DOJ). The government's approved-provider list places Carfax under “Commercial Customers Only”: it “offers NMVTIS data to commercial customers in California only,” and consumers “CANNOT receive NMVTIS Vehicle History Reports from Carfax.” If you want an official NMVTIS title report, buy it from a consumer provider on that list.
Is a Carfax report worth paying for?
The FTC recommends getting a vehicle history report before buying a used car (FTC). Whether you need to pay for one depends on the car:
- Buying from a dealer: ask the dealer for its copy of the report before paying for your own.
- Buying privately: run the VIN yourself, through a site you choose. The FTC warns of scams where a fake buyer insists a seller get a report from one specific website (FTC).
- Checking title problems first: start with a title check, then pay for a full report on the cars that pass. Our VIN check gives a free preview, and the used car report covers salvage and auction history. See also Carfax alternatives.
Carfax also offers Carfax Car Care, a “free car maintenance tracker” that stores service history and flags open recalls for a car you already own.
Is Carfax legit: FAQ
Is Carfax a legit company?
Yes. Carfax is a reporting segment of Mobility Global Inc., which S&P Global spun off as a separate public company on July 1, 2026, per Mobility Global’s SEC filings. Those filings say Carfax holds more than 38 billion vehicle history records from more than 177,000 sources. The FTC names Carfax as a source of accident and repair history, while noting it doesn’t endorse any service.
Is a Carfax report worth it?
It is worth reading before you buy a used car, and the FTC recommends getting a vehicle history report first. But Carfax itself says it “does not have the complete history of every vehicle” and only reports information supplied to it. If you are buying from a dealer, ask for the dealer’s copy before paying for your own.
Is Carfax accurate?
It is only as complete as what gets reported. Carfax states its products “are based only on information supplied to CARFAX,” and its parent’s SEC filing says its processes “cannot ensure absolute accuracy.” An accident that was never reported to police or insurance, or repairs paid in cash at an independent shop, may not show up.
Is it okay to buy a car from Carfax?
Carfax lists cars; it doesn’t own the inventory. Its parent’s SEC filing describes a dealer subscription product that “lets dealers post vehicles for sale on CARFAX’s high-traffic website and apps.” You buy from the listing dealer, so check that dealer’s terms and reputation, and get an independent inspection.
Can I get an official NMVTIS report from Carfax?
No. The Justice Department’s NMVTIS site lists Carfax as offering NMVTIS data to commercial customers in California only, and states that consumers “CANNOT receive NMVTIS Vehicle History Reports from Carfax.” Consumers can buy NMVTIS reports from the approved providers listed at vehiclehistory.gov.
What is the difference between Carfax and NMVTIS?
NMVTIS is the federal title database. Its reports cover five indicators: current title state and date, title brands, odometer, total loss and salvage. Repair, recall and maintenance history are deliberately left out. Carfax adds accident, service, ownership and type-of-use records from its own sources.
