Proof of delivery is the closing document on a freight move. It is the shipper's confirmation that the carrier fulfilled their delivery obligation and the consignee's acknowledgment of receipt. Without a signed POD, shippers cannot confirm delivery, carriers cannot close out billing, and consignees cannot trigger accounts payable processes.

In truckload shipping, the BOL serves as the POD when signed at delivery. The driver leaves with a copy; the carrier retains the original and can provide copies on request. In LTL, carriers generate a separate delivery receipt that the consignee signs, which is then associated with the shipment's PRO number in the carrier's tracking system.

The POD is critical in three specific scenarios. First, freight claims: if a consignee notes damage on the POD before signing (noting exceptions), that exception is the foundation of a cargo claim against the carrier. Without documented exceptions at delivery, proving that damage occurred in transit — rather than before pickup or during unloading — becomes significantly harder.

Second, payment terms: many shipper-consignee payment agreements specify that payment is due a set number of days after the POD date. Delayed or missing PODs delay payment. Shippers who need prompt PODs should establish expectations with carriers at the contract stage.

Third, detention disputes: the POD timestamp is often used as evidence in detention charge disputes, showing exactly when the driver arrived and when the signed receipt was issued.

Digital PODs — electronic signatures captured on a handheld device — are increasingly standard. They are transmitted to the carrier's system in real time, making copies available through tracking portals within hours of delivery rather than days.
