LincMad Telephone Area Codes & Splits

Evolution of North American Area Codes, 1947 to 2012

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, the trend towards area code overlays instead of splits is accelerating: the last split in the United States was in 2007, and the last split in Canada was in 1999. Overlay codes are shown in red. Updated 2015‑09‑22.

(Also check the cumulative listing of area code splits since 1980. For example, if you have an old telephone number and don't know the new area code, you can check it against this chart.)

¶ The tiny town of Hyder, Alaska, receives telephone service from neighboring Stewart, B.C., Canada, and therefore uses area code 250. Calls to Hyder — whether originating in the US, Canada, or elsewhere — will be billed as calls to British Columbia, Canada. The other 99.99% of Alaska is in area code 907.

§ Area code 321 in Florida is both an overlay on area code 407 (Orlando) and a separate standalone area code for the "Space Coast" area.

Atlanta, Dallas, and Houston all had area code splits that were later converted to overlays. The original split codes (770, 972, and 281, respectively) are not indicated as overlays in the chart above.
