Currently, there are over 320 area codes across the United States. This number grows periodically as new area codes are added to meet the demand for phone numbers in densely populated areas or regions with high growth.
An area code is a three-digit number that precedes a seven-digit telephone number. It designates a specific geographic region within the United States or, in some cases, a group of services, such as toll-free numbers. Area codes help route calls within the North American Numbering Plan (NANP) to the correct location or service.
Area codes can be found using our online searching directory or area code maps, which display the codes associated with each region. Simply search for the city or state in question, and the area code will be listed along with other details about that region’s phone numbering.
