International amateur radio is subject to which organization?

• A. International Telecommunication Union (ITU)
• B. Federal Communications Commission (FCC)
• C. International Maritime Organization (IMO)
• D. North Atlantic Treaty Organization (NATO)

Answer: (A)

International coordination of radio spectrum and the rules for how radio services operate across borders are set by a United Nations agency that focuses on information and communication technologies. This organization maintains the international Radio Regulations, designates frequency bands, and helps harmonize how amateur radio is used worldwide. That means activities in different countries align with these international rules, while each country also has its own regulator to issue licenses and enforce regulations locally. In the United States, for example, that role is played by the FCC. Other organizations like the International Maritime Organization deal with ships’ communications, and NATO is a military alliance without authority over amateur radio regulation. So the organization that governs international amateur radio is ITU.
