<DIV><FONT face=Arial size=2>In some places 0+ is intra-lata operator assisted
and 00+ inter-lata operator assisted. In other places (like CO) we don't
have LATAs.</FONT></DIV>

<DIV><FONT face=Arial size=2>The NA number plan has been and still is much more
uniform than in many other countries. However, given the variety of
unregulated providers plus the breakup of the Bell system, it has diverged
some. The basic NPA-NXX-XXXX scheme has remained (so far) but details like
1 being optional on Cell phones, whether 1 means "area code to follow" or "this
is a toll call", whether local calls and/or calls within an area code require 7
or 10 digits is up to the LEC in each case--its a bit confusing. Then
there are LATAs (or not) and some places which have mileage based charges that
aren't quite long distance, but aren't local, either (ZUM). </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I managed a PBX in the 805 area code where the LEC
provided 7 digit local dialing, 8 digit toll dialing within the A/C and 11 digit
toll dialing outside the area code. Except that two prefixes from the 818
(originally 213) A/C was also local and you had to dial 11 digits for that (1+)
even though it was local. Furthermore, it was run by a different LEC that
had different dialing rules, so making the call in the opposite direction had
different rules (10 digit for local in the area code, if I recall). A bit
confusing for someone who lived in one community and worked in the other and
made calls both directions between the two.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We're pretty well off here in CO. We do have
an overlay area code (303 and 720) so everything is 10 digits, but everything in
those two area codes is local, there are no ZUMs or LATAs. The only
abnormality is that there are a couple of other areas codes in the state that
have different tariff rules than out of state, but it doesn't affect dialing,
only cost and provider.</FONT></DIV>
