  • Jane requests a police record from the Ghana Post Office.

Verification at Ghana Post Office

  • The Ghana Post Office checks Jane's ID.

Request to Ethiopian Post Office:

  • Ghana Post Office requests Jane's police record from the Ethiopian Post Office, providing:
    • Jane's certificate.
    • Ghana Post Office certificate.

Liaison and Verification at Ethiopian Post Office:

  • Ethiopian Post Office liaises with local authorities to obtain the police record content.
  • The content is hashed.
  • The hash is linked together with:

- Ethiopia Post will encrypt the doc with private KSK

Business Case: Enhancing Cross-Border Document Verification in the Global Postal Sector

Scenario Overview

Jane, a citizen of Ghana, needs her police record for a specific purpose. She initiates the process by requesting the record from the Ghana Post Office. The subsequent steps involve verification, cross-border communication, and collaboration with the Ethiopian Post Office.

Key Steps:

Initiation: Jane’s Request

  1. Jane approaches the Ghana Post Office to obtain her police record.
  2. The Ghana Post Office receives her request and begins the verification process.

Verification at Ghana Post Office

  1. The Ghana Post Office verifies Jane’s identity using her official ID.
  2. This step ensures that the request is legitimate and that the document will be issued to the correct individual.

Request to Ethiopian Post Office

  1. The Ghana Post Office initiates communication with the Ethiopian Post Office.
  2. They request Jane’s police record, providing the necessary context:
    1. Jane’s certificate (proof of identity).
    2. Ghana Post Office certificate (indicating their role as the requesting entity).

Liaison and Verification at Ethiopian Post Office

  1. The Ethiopian Post Office collaborates with local authorities in Ethiopia.
  2. They obtain the content of Jane’s police record.
  3. To ensure data integrity and security, the content is hashed.
  4. The hash value is concatenated with:
    1. Jane’s certificate (to establish ownership).
    2. Ethiopian Post Office certificate (to verify the document’s origin).

Industry Impact:

Efficient Cross-Border Processes:

  1. By leveraging the existing postal network, cross-border document requests become more streamlined.
  2. Collaboration between postal operators facilitates efficient data exchange.

Trust and Security:

  1. The verification process ensures that the police record is genuine and belongs to Jane.
  2. Hashing and concatenation enhance data security, preventing tampering or unauthorized access.

Global Standardization:

  1. Implementing similar processes across different postal administrations promotes consistency.
  2. Standardized procedures improve overall industry performance.

E-Commerce and Digital Services:

  1. As posts move into e-commerce and online marketplaces, secure document handling becomes crucial.
  2. The ability to verify and share documents seamlessly contributes to the industry’s digital transformation.

Industry Trends:

E-Commerce Growth:

  1. Posts are increasingly involved in e-commerce logistics and last-mile delivery.
  2. Efficient document handling supports this trend.

Urban Logistics Challenges:

  1. Urbanization poses challenges for last-mile delivery.
  2. Streamlined processes like cross-border document verification help address these challenges.


The collaboration between the Ghana Post Office and the Ethiopian Post Office exemplifies how the global postal sector can enhance its services through efficient cross-border communication, trust-building, and adherence to industry standards. By ensuring the integrity of documents and embracing digital solutions, postal operators contribute to a more connected and secure world.
