Evolution of North American Area Codes, 1947 to 2023

The original 86 area codes became over 400

The following chart shows the original 86 area codes, plus the regions that were added later, and the area codes now used in those regions. Many of the new area codes were created by simple geographic splits, but in several cases the existing boundary was realigned and/or a new area code was created from portions of two old area codes. However, area code splits have entirely given way to overlays: the last split in the United States was in 2007, and the last split in Canada was in 1999.

Table notation

Notation change: Overlay codes are prefixed with an @ symbol. Unconfirmed listings are prefixed with a ? question mark. Area codes marked with an asterisk✻ are comprised of parts of two or more original 1947 area codes. Area codes in (parentheses) are planned overlays for 2023 to about 2025. A “primary” area code is one that at some point was the only area code for its geographic territory. The listing of area codes is now ordered as follows:
