WEX vs. Comdata: Accepting Locations
| WEX | Comdata | |
| Accepting locations | 95% of stations in the U.S. | 8,000 truck stops |
The theme of this comparison article is that WEX is built for all types of fleets while Comdata is made for trucking fleets and more specifically over-the-road (OTR) trucking fleets. WEX is made for businesses that want the flexibility to fuel at any station, which is why WEX is accepted at 95% of stations nationwide.
On the other hand, Comdata is designed for trucking companies that primarily fuel at truck stops due to the size of their vehicles and added driver conveniences such as overnight parking, food, and showers. As a result, Comdata is mainly accepted at truck stop locations. To expand it's acceptance, Comdata also offers an optional Mastercard add-on, enabling purchases anywhere Mastercard is accepted. However, fees and discounts can differ between transactions made on the Comdata network and those processed through the wider Mastercard network.

Both fuel cards offer mobile apps that allow drivers to authorize transactions at the pump, significantly reducing the risk of fraud. WEX uses a two-factor authentication (2FA) app that sends a code only when the driver is physically at a fuel station. Comdata offers a similar system for drivers to activate the card through the app, and the authorization automatically times out after fueling.
In addition, both cards include advanced fraud protection features that verify the truck’s location and fuel tank level before approving a transaction. WEX calls this technology SecureFuel, while Comdata refers to it as Proximity Solutions.
