Customer Information

These are questions frequently asked from the Public. 


  • How does one identify which card belongs to which vehicle?

GSA Fleet has the vehicle tag numbers embossed on the fleet cards. The “card to vehicle” concept applies to GSA fleet vehicles only, and may not be true for an agency-owned or commercially leased vehicle. 


  • How is a customer PIN number assigned?

A customers’ PIN number will not be provided over Internet. Please contact a local Fleet Management Center for more information.

  • What if a GSA Fleet vehicle breaks down and a tow is needed?

Call the Maintenance Control Center phone number on the back of the card or call your local Fleet Management Center. In many parts of the country, GSA Fleet has contracts or agreements with local towing companies which help save money and keep your rates low. After business hours (6:00 a.m. to 7:00 p.m. (CST), a toll-free number will be provided for a towing company which accepts the WEX Fleet card. DO NOT call for road-side assistance without first calling the Maintenance Control Center.

  • Is it possible to use a vendor that does not accept the WEX Fleet card?

Yes. The GSA Fleet card has a MasterCard backup. For maintenance or fuel purchases simply turn card over and call the merchant contact number on the back. The merchant will be provided a MasterCard number over the phone upon approval.

  • How can a customer obtain maintenance using my GSA Fleet WEX card?

For maintenance under $100 – Merchants can either electronically accept the WEX Fleet card or call in the transactions to 1(866) 939-4472 to receive a MasterCard number. For maintenance over $100 or any accident damage – Merchants should phone GSA Fleet PRIOR to doing the work 1(866) 400-0411, and receive a MasterCard number when the work is completed. If a vehicle requires after-hours emergency repairs when the MCC is closed, Citibank/WEX can authorize the use of a card for purchases up to $500. Emergency repairs are vehicle breakdowns, accidents, tire blow out, towing, etc.

  • What types of purchases are authorized?

In accordance with the Federal Acquisition Regulation (FAR 13.1301), the governmentwide commercial Fleet Services Card is authorized for the purchase of fuel, maintenance and repair of Government owned/operated motor vehicles.

Fleet Services Cards are issued to specific vehicles and should only be used for the vehicle to which it is issued.

An agency who leases a vehicle through GSA is the government’s agent for each purchase made with the Fleet Services Card and responsible for each transaction. The agency is also responsible for ensuring the compliance with all applicable GSA Fleet and agency regulations and procedures.

  • Authorized Transactions
  • The purchase of regular unleaded self-service gasoline from service stations offering the lowest price, except when:
    • The vehicle requires diesel fuel.

    • The use of premium grade fuel is approved by the servicing GSA Fleet Management Center.
    • The operator has a physical limitation preventing him or her from pumping fuel and/or severe weather conditions exist.

  • How is the dollar limit increased on a GSA Fleet card?

Dollar limits on the new cards will be set based on the tank capacity of the vehicle. Pumps have merchant-set dollar limits built into the software that card providers can not override. As fuel prices rise, fleet card providers work with merchants to determine the pump shutoff limits that make the most economical sense, and the merchant determines the final limit.
