The US phone code is 1 because it was assigned based on the North American Numbering Plan (NANP) established in 1947. The US, being a dominant economic and military power at the time, and the first country to adopt an area-code system, was given the first choice. Consequently, the single-digit code '1' was chosen for simplicity and ease of dialing, reflecting its pioneering status in the development and implementation of the telephone system.
