BECOME A MEMBER
Membership in ITSO, currently comprised of 149-member States, is open to new membership by the Government of any member State of the United Nations or the International Telecommunication Union (ITU). A Government may join the Organization by officially depositing its instrument of ratification, acceptance, approval or accession to the Agreement with the Depositary of the treaty. Any Government signing the Agreement may do so without its signature being subject to ratification, acceptance or approval or with a declaration accompanying its signature that it is subject to ratification, acceptance or approval.
