ITU region and spectrum allocation

The International Telecommunication Union (ITU), in its International Radio Regulations, divides the world into three ITU regions for the purposes of managing the global radio spectrum. Each region has its own set of frequency allocations, the main reason for defining the regions.

• Region 1 comprises Europe, Africa, the former Soviet Union, Mongolia, and the Middle East west of the Persian Gulf, including Iraq. The western boundary is defined by Line B.

• Region 2 covers the Americas including Greenland and some of the eastern Pacific Islands. The eastern boundary is defined by Line B.

• Region 3 contains most of non-FSU Asia east of and including Iran, and most of Oceania.
