Site overview
This site contains information about the
North American Numbering Plan,
the telephone numbering scheme that serves the United States, Canada,
and several other countries and territories in the region.
The NANP divides the participating countries into area codes, each of which
is a three-digit number. Within each area code, a telephone number is always
7 digits, except for special codes like the 911 emergency number.
In the late 1990s, the NANP added new area codes at a rate unprecedented in
its 50-year history, with demand fueled primarily by the outdated system of
allocating blocks of numbers to telephone companies.
More efficient allocation methods, coupled with consolidation in the
telecommunications industry, have slowed the flood of new area codes to
barely a trickle, from 45 in 1997 to only 3 in 2007.
Notably, the introduction of new area codes has shifted decisively from
traditional area code splits to overlays. As of mid-2013, there are no
area code splits pending or planned anywhere in the NANP!
This site contains information about the original area codes from 1947,
their evolution to the current state, and future developments, including
area code splits and area code overlays.
