That is, of course, unless you live in Illinois or several other states
which provide public CN/A (Customer Name and Address) services, much
like a reverse directory bureau.  If I live in Chicago and someone
calls my line with CPID, I can know who they are in a matter of minutes
by dialing 769-9600 (I think that's right.. it's something like that).

And, at any rate, the telephone number identifies someone insofar as it
doesn't identify anyone else; being unique, there is always a way to find
it out.  The wife-beater who gets a call from his wife-in-hiding can
narrow her location down by the area code and prefix, then look through
the phone book for a few likely establishments (shelters, etc.) and pin
her down pretty quickly.

[Moderator's Note: The number for CNA in Chicago is 312-796-9600. Locally
it is a fifty cent call. They cover all of area code 312, and will give
you the name and address of listed numbers, or nothing if the number is
non-pub.   PT]

In the early 1960's when I lived in Edmonton, Alberta, a form of reverse
directory was included right in the public directory, as "Pink Pages".
Where the white pages might say

		Brader S L 12219 51st St ........... 477-7474

the pink ones would just have

		7474 Brader

as an entry under the heading 477; thus they were much shorter than the
white pages.  I was too young in those days to think of investigating
whether the pink pages listings included all phone numbers or only some
classes thereof, and I have no idea when they stopped doing that.

By the way, that was my actual phone number.  Best one I've ever had,
though for most of the time we had it, it was still GRanite 7-7474.
My present one has a pretty nice pattern, too: 488-6366.  Unfortunately,
the number 488-6636 belongs to a business.
