Whats the NP?
NP (Number Portability) The capability of keeping
the same telephone number when switching carriers
or services. It all started with 800 numbers,
which led to local number portability (LNP) and
later to wireless number portability (WLNP).
November 24, 2003 was known as "Cellphone
Independence" day because it was the first time
in the U.S. that customers in the top 100
metropolitan service areas (MSAs) could move
their telephone numbers to a different carrier.
In most cases, landline numbers can also be moved
to a cellular carrier.
