Several stakeholders are involved in the processing of the IPC Mail Registration Device: posts, ground handling agents and airlines. Each of them can use a different registration process and report accordingly. This often leads to a lack of visibility or the contradictory registration of data. IPC created the Mail Registration Device (MRD) to ensure visibility, reliability and performance of airmail transport. Accurately recording and capturing the transfer of responsibility from one party in the supply chain to another is critical.

How does it work?

The IPC MRD provides a complete view over handover processes between posts and airlines at both origin and destination, enabling seamless visibility from outbound post to inbound post. The device is installed by postal operators at the point where handlers from the airlines deliver postal containers to the postal staff and/or where postal staff hand over mail consignments to airlines, which usually takes place at the entrance of the air mail units at the airport. 

The MRD consists of a touchscreen terminal, a scanner, a label printer and technical infrastructure to manage the data produced.

Two separate and independent processes can be registered through an MRD: the delivery of mail consignments at destination (Proof Of Delivery - POD MRD) and the handover of mail consignments at origin (Proof of Custody - POC MRD).
Origin: at origin, the post scans receptacle IDs into handover equipment which is later staged for collection. The airline or handler records the transfer of custody at origin of each individual receptacle by a single scan of the nest/equipment ID using the POC MRD.

Destination: at destination the carrier attaches an MRD-created nest ID label to handover equipment after recording delivery at POD MRD (one scan per delivered handover unit). The post scans the IDs taken out of handover equipment delivered by the airline. Data is collected and consolidated by IPC. IPC then issues a Proof Of Custody and/or a Proof Of Delivery for the airline. This consolidation process allows for all stakeholders to receive Proof Of Custody/Delivery information at receptacle level, even if the registration process by the handler is only expected to take place at equipment level. IPC shares the consolidated data with everyone, free of charge, in order to ensure full visibility over the handover process.


  • Increased visibility and accountability for all parties
  • Provides clear data to identify operational improvement opportunities
  • Improves end to end transit times
