Q: How are US area codes assigned?

US area codes are assigned by the North American Numbering Plan Administrator (NANPA). Originally, area codes with 0 or 1 as the middle digit were assigned to geographic regions, with more populated areas receiving codes that were faster to dial on rotary phones. Today, new area codes are typically added as overlays to existing areas when the supply of available numbers runs low.

US area codes are part of the North American Numbering Plan (NANP), which was established in 1947 to simplify long-distance calling across the United States, Canada, and other participating countries. Each area code is a three-digit prefix that identifies a specific geographic region. As demand for phone numbers has grown with mobile phones and internet services, many areas have received additional overlay codes that serve the same geographic region.

Frequently Asked Questions About US Area Codes

The United States currently has over 330 active area codes spanning all 50 states and the District of Columbia. This number continues to grow as new overlay codes are introduced to meet increasing demand for phone numbers driven by mobile phones, VoIP services, and other telecommunications devices.

An area code is a three-digit number that identifies a specific geographic region within the North American Numbering Plan (NANP). Area codes are the first three digits of a 10-digit phone number and are used to route telephone calls to the correct region. They were first introduced in 1947 by AT&T and the Bell System to enable direct-dial long-distance calling without operator assistance.

US area codes are assigned by the North American Numbering Plan Administrator (NANPA). Originally, area codes with 0 or 1 as the middle digit were assigned to geographic regions, with more populated areas receiving codes that were faster to dial on rotary phones (lower digits = shorter dial time). For example, New York City got 212 and Los Angeles got 213. Today, new area codes are typically added as overlays to existing areas when the supply of available numbers runs low, rather than splitting the existing area.

In an area code split, the existing geographic area served by one area code is divided into two or more regions, each assigned a different area code. Some phone numbers keep the old code while others must change to the new one. In an overlay, a new area code is added to the same geographic area as an existing code. Both codes serve the same region, and all existing numbers keep their current area code. Overlays are now the preferred method because they avoid the disruption of changing existing phone numbers.

In areas with overlay area codes, 10-digit dialing (area code + 7-digit number) is mandatory because two different phone numbers could have the same 7-digit local number but different area codes. Without the area code, the phone system would not know which number you intend to reach. As of 2021, 10-digit dialing is also required nationwide for calls to the 988 Suicide & Crisis Lifeline.
