Nigeria plugs passport system into global ICAO verification network

Nigeria has completed the integration of its electronic passport authentication system into the International Civil Aviation Organization’s Public Key Directory (PKD), a move that should end the verification snags Nigerian travellers often face at foreign border posts.

The Ministry of Interior and the Nigeria Immigration Service (NIS) carried out the work, uploading all of the country’s digital signing certificates, known as CSCAs, into the ICAO directory.

What that means in practice: border control systems in any of the 90-plus ICAO PKD member states can now instantly authenticate Nigerian e-passports. The system checks that the passport is genuine, hasn’t been tampered with, and was issued by a legitimate authority.

The NIS described the integration as establishing a “chain of trust” that allows real-time verification without human intervention or manual cross-checking.

The service said the milestone strengthens both the security and global acceptance of Nigeria’s travel documents. It also framed the achievement as part of President Bola Tinubu’s Renewed Hope Agenda, and reaffirmed its commitment to seamless border clearance for Nigerian passport holders.

The ICAO PKD is a global repository where countries exchange the digital certificates needed to authenticate machine-readable travel documents. By joining the network, Nigeria now sits alongside other nations in a secure, interoperable verification system that should cut delays at immigration counters and boost the passport’s international standing.
