What documentation is typically required to process a travel claim?

• A. Official orders and travel authorization only
• B. Vouchers only
• C. Receipts only
• D. Official orders, travel authorization, vouchers, and receipts or per diem documentation

Answer: (D)

Processing a travel claim requires complete documentation to prove the trip was properly authorized, the travel occurred, and the costs claimed are valid. Official orders establish the authority to travel and set the assignment, while travel authorization confirms the specific trip details and timing. Vouchers are the reimbursement request that ties the approved authorization to the incurred costs, and receipts or per diem documentation provide the substantiation for expenses or the justification for per diem. Each piece serves a distinct purpose, and together they create a verifiable trail for audit and payment. Therefore, the full set—official orders, travel authorization, vouchers, and receipts or per diem documentation—is typically required.
