[comp.dcom.telecom] Information Wanted on CNA

sak@athena.mit.edu (Don Saklad) (03/21/90)

 ...from a stack of pending telecommunications questions:

Does anyone know something, anything or everything about CNA, customer
name and address service?


[Moderator's Note: Customer Name and Address Bureau (or Service) is
usually only an inter-telco arrangment, where authorized employees of
one telco (such as the billing department) can get the name and
address of a customer whose charges have to be billed collect, etc.
One exception to the rule that CNA can only be used internally by
telcos is the one operated by Illinois Bell specifically for the
public.  (They also have an internal version for their own use.)  By
dialing 312 (or 708, it matters not) 796-9600 you reach operators at
Illinois Bell's Chicago-Wabash central office who do reverse directory
lookups at the rate of 35 cents per two numbers. You provide the
312/708 number; they respond with the name and address where the
service is located.  If the service is non-pub, that's your tough
luck; they don't have it available on their terminals. As stated
above, most telcos do not offer this service to the public.  Are there
others besides Illinois Bell, which also does it for Central Tel on
the northwest side?  PT]

Is there any legal restriction that prevents me from offering this
service myself?  It would be a simple matter to set up the database on
a computer from the data contained in a (publicly-available) telephone
directory.  But would there be any market?  How often does anyone need
to get a name/address given a phone number?

[Moderator's Note: There is no legal restriction whatsoever ... just
be sure not to copy in bulk from the phone book; it is copyrighted.
And don't copy in bulk from Haines Criss Cross or similar; they are
copyrighted also.  Both Haines and the telcos put 'ringers' in their
book; i.e. non-existent, phake, phalse entries. These are inserted
only for the purpose of finding them in print in *someone else's book*
later on, so they can sue them for copyright violations. Of course,
most telcos will sell you the right to copy their books for the
purpose you describe. Haines pays Ameritech BIG $$$$$$$$$$ annually
for the right to key-punch their directories in reverse order once
Ameritech compiles it.  PT]
