2. ICAO will issue from time-to-time a “Supplement to Doc 9303.” The Supplement will contain
information intended to clarify, amplify or elaborate on issues with respect to travel document standards, as
well as to correct errors encountered from implementation experiences. It is intended that the information
contained in the Supplement will augment the existing guidance in Doc 9303 as well as in Technical Reports
issued by ICAO. The Supplement will be issued on a continuing and consistent basis.
The specifications of Doc 9303 should always be read in conjunction with the additional information set out in
the latest release of the Supplement which will be available on the ICAO web site at www.icao.int/mrtd.
