Understanding Area Code 404: Atlanta's Key Telephone Code

Area code 404 primarily covers the city of Atlanta itself and its immediate suburbs inside Interstate 285. Some examples include Candler-McAfee, College Park, East Point, Forest Park, Sandy Springs, and Tucker.

Area code 404 was established in 1947 as one of the original North American Numbering Plan (NANP) area codes. It represents a significant part of Atlanta's telecommunications history and infrastructure.

Due to population growth and increased demand for phone numbers, overlay area codes like 678, 470, and 943 were added to supplement the existing 404 area code.

The NPA code is 404. It's an overlay area code, meaning it shares geographic coverage with other area codes like 678, 470, and 943.

Major carriers in area code 404 include AT&T Inc., Verizon, T-Mobile, and Sprint, offering various services such as landline, wireless, and VoIP.

While 404 covers Atlanta and its inner suburbs, Atlanta itself is located at approximately 33.749 latitude and -84.38798 longitude. Surrounding areas within the I-285 perimeter also fall under 404.

10-digit dialing requires callers to dial both the area code and the seven-digit phone number. It's necessary due to the presence of multiple overlay area codes within the same geographic region.

There are approximately 7.92 million potential phone numbers within area code 404, based on 792 central office prefixes.

You can find more information at the Georgia Public Service Commission website and the North American Numbering Plan Administrator website.

Originally, 404 covered a larger area. Over time, new area codes like 912 (1954 for southern Georgia), 706 (1992 for northern Georgia), and 770 (1995 for Atlanta suburbs) were introduced to accommodate growth.

Area code 678 was introduced in 1998, 470 in 2001, and 943 was added in 2022.

Nearing exhaustion means that almost all available phone number combinations within that area code have been assigned. This necessitates the introduction of new area codes.

NPA stands for Numbering Plan Area. It is a three-digit code that precedes the seven-digit phone number and represents a specific geographic region.

Area code 404 is a North American Numbering Plan (NANP) telephone area code primarily serving Atlanta, Georgia, and its immediate suburbs. Established in 1947, it's one of the original area codes and remains essential for the region's communication infrastructure.

Area code 404 covers the city of Atlanta and its surrounding suburbs within Interstate 285. This includes areas like Candler-McAfee, College Park, East Point, Forest Park, Sandy Springs, and Tucker.

Area code 404 has approximately 7.92 million available phone numbers, based on 792 central offices. However, due to high utilization, the area code has neared exhaustion, leading to the introduction of overlay codes like 678, 470, and 943.

Atlanta's multiple area codes (404, 678, 470, 943) are due to population growth and increased demand for phone numbers. As the original 404 neared exhaustion, overlays were implemented starting in 1998 with 678 to accommodate the need.

Area code 404 was established in 1947 as one of the original North American Numbering Plan area codes. It initially covered a larger area of Georgia, but portions were later reassigned to area codes 912 and 706.

Ten-digit dialing is required for all calls within area code 404, including local calls. This complies with NANPA regulations and number pooling practices in the region.

Area code 404 has multiple overlay codes: 678 (introduced in 1998), 470 (added in 2001), and most recently, 943 (added in 2022). These overlays help manage the high demand for phone numbers within the 404 region.

In addition to the original 404, Atlanta uses overlay area codes 678, 470, and 943. These were introduced over time to address the increasing demand for phone numbers due to population and technology growth.

Sandy Springs, Georgia, is included within the 404 area code, along with several other Atlanta suburbs. Due to the high utilization of numbers, it may also be served by overlay codes such as 678, 470, or 943.

Area code 404 is regulated by the Georgia Public Service Commission (GPSC), which oversees telecommunications services in the state. The GPSC ensures compliance with NANPA regulations, including ten-digit dialing and number pooling.

Area code 943 was introduced as an overlay to 404 in 2022. This addition reflects the continuing high demand for phone numbers in the Atlanta area, even with existing overlays like 678 and 470.

Major telecommunications carriers operating within area code 404 include AT&T (formerly BellSouth), Verizon, T-Mobile, and Sprint. They offer a range of services including landline, wireless, and VoIP.
