A while ago we had a discussion on CO's that straddle area code
boundaries and are dialable as more than one.  If you remember, we
found one here in the Omaha area which was -- in SOME cases --
dialable either as 402 or 712.  I recently returned from a trip to the
Black Hills area of South Dakota.  (Deadwood: Las Vegas of the
Midwest. ;-) I stumbled upon many examples of CO's split between the
308/605 codes or the 402/605 codes.  I don't know how many of these
there are.  There may be hundreds.  I saw more in the local phone
books than I can remember.
 
These were cases where there are communities right on or near the
Nebraska - South Dakota border.  They often appear in such form as
'Whatnot, SD' and 'South Whatnot, NE' or 'Cornholdt, NE' and 'North
Cornholdt, SD'.  (I forget the actual names, but these are typical.)
These communities are VERY small.  If you think Omaha is out in the
toolies ... we are talking major sticks here.  These towns are only a
few hundred in population, if that.  From the limited amount of
dorking around I found time and place to do, I determined that these
were all SxS offices (with some REALLY funky ringback and busy tones)
which maybe served 100 or so subscribers on both sides of the border.
These offices came nowhere near to filling up a complete 1000's group
out of an office code.  In some cases, the NNX were the same in both
area codes, in some, they were different.
 
In every case, the same lines (and vacant levels, etc.) could be
reached via either AC.  My conclusion is that in the 48 states, there
are potentially thousands of examples of 'split' central offices if we
consider all of the rural communities that are adjacent to or straddle
state lines.

Good Day!       JSW

[Moderator's Note: An example of that here was 414-396 / 312-396.
Antioch, IL was 312-395. North Antioch, WI is 414-396, but was dialable
from *Antioch only* as 396+4D. To reach the *real* 312-396 residents
of the village of Antioch had to dial one plus. 414-396 is Illinois
Bell's one incursion into the 414 area. Now, Antioch is 708, but so is
Blue Island, IL where the 'real' 708-396 lives. I don't know what they
do up there now.  PAT]
