I understand now the phoneco offers reverse information, that is, given a phone number they'll return the person's name and address.
For personal security, many people don't want their home address readilly available, but they still want to be listed in the book so people can find and call them. I called the phoneco to ask if addresses could be deleted or made generic (ie street name only, no house number, or town only) and they said no except for very special cases (ie a cop). Apartment dwellers can have the building address shown, not their apartment number.
It seems to me the phoneco should allow no addresses freely if that's what the customer wants.
