Predictions for New Area Codes

The information below relates to new area codes that are expected in the 2020s. Except where noted, the new area codes have not yet been announced officially, but the predictions are guesses based on other publicly available information. In the table below, “NPA” is the current area code, “Exhaust” is the date (calendar quarter) the current area code is projected to run out of number blocks, and “New” is my prediction for the new area code that will be assigned. The new area code typically takes effect six months to a year before the projected exhaust date. If a full date is given, that is the confirmed official effective date of the new area code.

It is certainly possible — indeed likely — that some of these predictions will be proven wrong, but I expect my accuracy to be 80+%. (Predictions that have been officially confirmed are listed in gray✔; predictions that have been proven wrong are listed in red🚫.) However, with limited exceptions, this information has not been corroborated with NANPA, with any state agency, or with any telephone company; it is therefore provided entirely without warranty of any kind.
