How to become a Member State

If the State is a Member of the United Nations:
  • it becomes a Member State of the ITU by acceding to the Constitution and the Convention of the International Telecommunication Union (Geneva, 1992). Such accession shall be made simultaneously in the form of one single document covering both the Constitution and the Convention;
  • the instrument of accession shall be deposited with the ITU Secretary-General.

If the State is not a Member of the United Nations:
  • the application for membership needs to have a secured approval by two-thirds of the Member States of the Union;

  • after such approval, the admission procedure is the same as described above in the form of one single document.
