Area Code and LATA
Maps
LATA stands for Local Access Transport Area
LATAs were
introduced with the break-up of
the Bell System
The LATA boundary
delineates the point where
your call is handed off from your local carrier
to your long-distance company
With the Telecom
Act of 1996, some customers
can now have one company handle their local,
Intra-LATA long-distance and Inter-LATA
long distance calls.
