The Penn Hills Branch is in the Pennsylvania 1 District of the Atlantic Area.
Every Postal Service-owned vehicle is assigned a Voyager Fleet card (Voyager card) to pay for its commercially purchased fuel, oil, and routine maintenance. U.S. Bank operates the program and Voyager provides a weekly electronic transaction detail file of all card transactions to the Postal Service’s Fuel Asset Management System (FAMS) eFleet application. FAMS provides a monthly Reconciliation Exception Report, capturing transactions categorized as “high‑risk,” which may result from fraudulent activity. Each month the Postal Service unit manager is responsible for ensuring that driver receipts are reconciled in FAMS. The review is critical since the Postal Service automatically pays U.S. Bank weekly for all Voyager card charges.
Employees must use their unique personal identification number (PIN) in conjunction with the Voyager card. Unit managers are responsible for electronically managing PINs, including creating, modifying, and terminating PINs in the Fleet Commander Online (FCO) system. They must also complete semiannual driver certifications to ensure the accuracy and completeness of employee PIN information.
The OIG used data analytics to identify offices with potentially fraudulent Voyager card activity. The Penn Hills Branch had 1,807 transactions posted from October 1, 2020, through March 31, 2021, totaling $65,062. This included 109 transactions flagged as high‑risk in FAMS.
Our objective was to determine whether Voyager card PINs were properly managed, and Voyager card transactions were properly reconciled at the Pittsburgh, PA, Penn Hills Branch.
