Arizona is a southwestern state known for its diverse climates that include arid desert and vast forests. The Capital city of Phoenix is the sixth most populous city nationwide and home to over 1.5 million residents. Over the course of its 105 year history, the state has been split into several different area codes and is currently home to 5 Arizona area codes. Area code 602 served as Arizona’s only area code for 48 years until 1995 when area code 520 was introduced to begin serving the southern city of Tucson and the majority of the southeastern part of the state. In the mid-90’s, explosive growth prompted a further split in the Phoenix metropolitan area (also known as the Valley of the Sun). Area code 623 was established to serve the West Valley and northwestern suburbs while eastern suburbs received area code 480. In 2001, area code 928 was introduced and covers northern, eastern and western portions of Arizona. Learn more about the history behind each area code:
