The frequency allocations of which ITU region apply to radio amateurs operating in North and South America?

The International Telecommunication Union (ITU) divides the world into three distinct regions for the purpose of managing the global radio spectrum. This helps coordinate frequency allocations among different continents and countries. Region 1 encompasses Europe, Africa, the Middle East, and northern Asia. Region 2 covers all of North and South America, including Hawaii and Greenland. Region 3 includes the rest of Asia and most of Oceania, including Australia and New Zealand. Therefore, amateur operators in North and South America must follow the frequency allocations designated specifically for ITU Region 2.
