Each GSA Fleet vehicle has a corresponding GSA Fleet Services Card. The eight-digit vehicle tag number is embossed on the face of the card — for example — G12-3456A. Use the GSA Fleet Card to pay for fuel and maintenance for your GSA Fleet-leased vehicle. The GSA Fleet Card is accepted at 95% of U.S. fuel stations and 45,000 service locations in all 50 states, U.S. territories, and Canada.
Each agency is responsible for issuing a fleet card task order. In addition to GSA Fleet, the Departments of Commerce, State, Homeland Security, and Agriculture have all chosen WEX as their fleet card. To see which fleet card federal agency vehicles are using, feel free to contact GSA SmartPay.
For issues using your GSA Fleet Card, call 866-WEX-4GSA (866-939-4472).
Authorized purchases — According to Federal Acquisition Regulation 13.301, you are authorized to use your GSA Fleet Card for the purchase of fuel, maintenance, and repair of government owned and operated motor vehicles. A GSA Fleet Card is issued to a specific vehicle and should only be used for the corresponding vehicle.
The leasing agency is the government’s agent for each purchase made with the GSA Fleet Card and is responsible for each transaction. The agency is also responsible for ensuring compliance with applicable GSA Fleet and agency regulations and procedures.
Authorized transactions
Unauthorized transactions
GSA Fleet Cards will continue to function as normal when there is a government shutdown, unless there are agency-specific requests to disable the cards.
Check with your agency regarding the use of both GSA Fleet-leased vehicles and Fleet cards due to appropriation limitations during a shutdown. You may not be authorized to use your card if your agency has determined you are not an exempt employee during the shutdown.
If you need to reach WEX customer service during a shutdown, call the number on the back of the card.
GSA Fleet vehicles are easily identifiable by the license plate and payment method. License plates on GSA Fleet vehicles have a G preceding the alphanumeric sequence. If you encounter a GSA Fleet vehicle without a GSA license plate, ask the driver to provide the GSA Fleet Service Card. The vehicle tag number is located in the lower left corner of the card. If the vehicle has GSA tags, make sure the vehicle license plate matches the number listed on the GSA Fleet Service Card.
