Mr. Peterson might be interested in knowing that getting an
unlisted phone number, or excluding one's address from the
telephone book, in no way impedes marketers armed with a phone
number who wish to obtain your name and address. Several
commercial "matching" services now exist which use data from
magazine subscriber lists, business customer databases, and other
pools of personal data -- many of which include phone numbers.
Another source, thanks to lax disclosure laws, is credit bureaus.
While credit bureaus are prevented by the Fair Credit Reporting
Act from disclosing credit information except under certain
circumstances, they're NOT prohibited from providing names and
addresses when given phone numbers (or vice versa).
 
Most matching firms claim a substantial hit rate on unlisted
numbers and numbers for which addresses are not printed in the
phone book.
