[comp.dcom.telecom] Strange "Calls To" on Phone Bill

DREUBEN@eagle.wesleyan.edu) (DOUGLAS SCOTT REUBEN) (10/04/90)

I've seen some of those "strange call to:" on bills as well, mainly
cellular phone bills and marine (ship-to-shore) phone bills.

I think they refer to certain areas within a larger metropolitan area.
I once got NYCZ2, which the nice people at NYTel told me was Mid-town
Manhattan.

I've also gotten SFCZ3, which, if it has anything to do with how
Pac*Bell does its "ZUM" (Zone Unit Measurement) system for local
calls, corresponds to "Zone 3" in the Pac*Bell SF book. (Is this so?)

I have an old NYTel directory (1979), and it lists the 15 New York
Zones, the 9 Nassau Zones, and the 9 Westchester Zones. I don't
believe that these are used for customer calling purposes anymore, as
they have been replaced (at least in the New York Metro area) by a
wider-area calling system. However, they do pop up on non-Telco bills
every so often, and every time I ask "why?", I am usually told "Oh,
the billing computer doesn't know the REAL name for the place..."
(Err..yeah...right..New York is *SUCH* a small,unheard of place that
anyone could have made that mistake! ;-) ).

I've never seen these occur for more rural areas, however...

(Oh, if anyone wants a copy of the 1979 Call Zone map, it's in all of
the New York City 1979 directories, or I can mail/fax you one if you
are really interested...)
