Question regarding the above: Does 1+ dialing have an impact?
(Instructions in Phila. & Pa. suburbs: dial local no. for local call;
1+local no. for elsewhere in 215 area; 1+areacode+local no. for outside
215 area. But in NJ, most places do NOT require 1+ for any within-areacode
calls, and [before N0X/N1X prefixes in 201 area] did not require 1+
for out-of-areacode calls.)
The U.S. telecom network is rapidly running out of
area codes. Discussion in ANSI telecommunications
network committees suggest that 1+ may be required
for all long distance calls, so that LD calls can
be recognized without restricting area codes to
N0N or N1N. For example, in the brave new world,
I could be in area code 222, and be dialed
as 1-222-555-1212.
