The Wilmington, NC, Magnolia Station is in the North Carolina District of the Atlantic Area.
Every Postal Service-owned vehicle is assigned a Voyager credit 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 Voyager card transactions to the Postal Service’s Fuel Asset Management System (FAMS) eFleet application. Site managers monitor Voyager card transactions in the 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 site manager ensures that their 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.
Transactions could be marked as high-risk in FAMS due to gallons of fuel purchased that exceeds the allowed maximum amount for the vehicle, unleaded super and plus fuel purchase, and/or potential sharing of personal identification numbers (PIN). These indicate questionable transactions which signify a higher risk of fraud.
OIG data analytics identified offices with potentially fraudulent Voyager card activity. The Wilmington, NC, Magnolia Station had 1,713 transactions at risk from October 1, 2020, through March 31, 2021, totaling $41,211. This included 282 Voyager card fuel purchases conducted with one employee’s PIN and valued at $6,084 and 60 transactions flagged as high-risk in FAMS.
The objective of this audit was to determine whether Voyager card PINs were properly managed, and Voyager card transactions were properly reconciled at the Wilmington, NC, Magnolia Station.
