UPU-IP – UPU Interconnection Platform

The UPU Interconnection Platform enables near real-time exchanges of postal-payment-related messages between designated operators (DOs).

The UPU-IP provides application programming interfaces (APIs) for DOs to interface with their national system: a technical setup that allows instant payments all the way to the point of sale.

Main functionalities

Register postal payment operation via API

Recording of postal payment operations by national system, including issue, payment, return of payment, cancellation or reimbursement.

Collect postal payment information via API

Tracking and retrieval of postal payment operations to check status and details of postal payments and retrieve, in batch mode, postal payments that are to be paid into an account.

Lock postal payments for a DO’s activity via API

Lock and unlock a postal payment while the DO performs a back-office operation to ensure that the exchange partner cannot record another operation (e.g. locking for further AML/CFT screening).

Automated processing of postal payment

Automatic expiration of postal payments that are past their validity date, allowing reimbursement by issuing DO.

Conversion to former M38 EDI format

For backward compatibility only: conversion and transport of M38 EDI messages to former the postal payments platform based on FTP EDI files. DOs migrating to the UPU-IP platform can continue exchanging with DOs that have not migrate to the UPU-IP (DOs using STEFI or IFS).

External systems proxy 

Relaying of postal payment events to external systems, if external system is the reference system (push mode).


The UPU-IP presents the following advantages:

Urgent service 

The paying DO can retrieve the payment as soon as it is issued to the UPU-IP. Payout on demand is now possible.

Payment anywhere 

The beneficiary can choose where the payout will take place: at a post office, at a sub-agent of the Post, or at a permitted external party’s site.


Activities are consolidated in one place.

  • All payments are stored in the UPU-IP database.
  • The UPU-IP acts as a central switch for real-time message routeing between DOs.
  • Designated operators can use the Bilateral Agreement Management System (BAMS), an application connected to the UPU-IP, to centrally negotiate, manage and retrieve bilateral agreement details.


Integrated solution

UPU-IP benefits from other PTC products:

  • BAMS – The UPU-IP interfaces with BAMS for bilateral agreements via online, real-time validation of international bilateral agreements between DOs, which are defined and managed in BAMS. MORE INFORMATION

  • PPS*Clearing – Postal payments that are eligible for clearing feed into the PPS*Clearing application for invoice generation: clearing and settlement of UPU-IP postal payments is available in PPS*Clearing. The UPU-IP also retrieves exchange rate feeds from PPS*Clearing. MORE INFORMATION

  • QCS Finance – Postal payment information is available via QCS Finance to allow the application to track and trace postal payments and generate activity and volume reports. MORE INFORMATION

Extension capabilities 

Extension capabilities with the option of integrating external solutions

The UPU-IP allows for the integration of solutions from the DO’s remittance partners. DOs offering postal payment services via a local agent can authorize direct connection of their partner solution to the UPU-IP and thus expand the available points of sale.
