About Arizona
Arizona is a southwestern U.S. state covering approximately 295,253 square kilometres, known for its deserts, mountains, and vibrant cities. It is home to more than 7 million residents, with Phoenix being the largest metropolitan area. Arizona’s economy is diverse, including technology, manufacturing, tourism, and energy, making it a strong region for business and growth.
History of 623 Area Code
Area code 602 was the first area code in Arizona, assigned in 1947 to cover the entire state. As Phoenix grew and the demand for phone numbers increased, it became necessary to create new area codes. In 1999, area code 623 was introduced as a split from 602 to serve the western part of the Phoenix metropolitan area. At the same time, area code 480 was created for the eastern part of Phoenix, while 602 continued to serve central Phoenix.
Before 623 was created, 602 had already been split once in 1995 to create area code 520 for southern Arizona, including Tucson. Later, in 2001, area code 928 was introduced to cover northern and western Arizona, splitting from the 520 region.
Today, area code 623 is one of five area codes in Arizona, alongside 602, 480, 520, and 928. The creation of 623 allowed the western Phoenix area to have more phone numbers while keeping 602 for central Phoenix, and the introduction of overlays and splits in the state has ensured enough numbers for the growing population.
