The ICAO Master List

The ICAO Master List contains the Country Signing Certificate Authority (CSCA) public key certificates of ICAO PKD members that have been passed to ICAO through diplomatic channels and are therefore trusted by ICAO. The Master List, prepared in conformance to ICAO Doc9303 specifications, is intended as an efficient means to distribute CSCA certificates that can be used for e-passport verification. ​Distribution of the Master List is intended to be complementary to bilateral distribution. Furthermore, its publication complements the publication of Master Lists by other entities and states in the PKD and elsewhere.


The Master List is digitally signed using an ICAO Master List Signer Certificate that is itself signed by the United Nations CSCA, both of which are included in the Master List in accordance with ICAO Doc9303. ICAO can provide the UN CSCA public key certificate to States upon request.


Master List Contents

Inclusion of certificates in the Master List is based on the ICAO Master List policy and procedure, available here.
