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.

anyone’s guess 🙈🎯
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.
It is much more difficult to predict the new area code to be added to
an area that already has an overlay, and somewhat difficult even in
non-overlay areas that now have 10-digit
local calling due to the 988 mandate. However, Canadian authorities
recently announced several additional codes for expected
overlays in the next decade.
NANPA has also announced several codes that are reserved for future
expansion of the 500 non-geographic services code:
535, 538, 542, 543, 545, 546, 547, 549,
550, 552, 553, 554, 556, 558, 569, 578, and 589.
Those area codes will not be assigned for any geographic area code relief.
