North American area code 480 is a telephone area code in Arizona serving the eastern and northern portions of the Phoenix metropolitan area. It was created on April 1, 1999 in a three - way split of area code 602, when it was apparent that the Valley of the Sun was growing too fast for it to remain entirely in one area code. Generally, 480 is coextensive with the East Valley, while most of the West Valley is area code 623 and most of Phoenix itself remained in 602.
