So an invoice for advertising in a Yellow Pages directory may have nothing to do with the Yellow Pages produced and distributed by your local telephone company.
Some independent companies produce alternative business directories.
The value of advertising in them depends on how well they are promoted and distributed. Con artists may actually produce the directories that businesses pay to advertise in, but will only have limited numbers printed and will distribute them to other advertisers rather than to potential customers. If you are solicited to advertise in a directory or other publication, check out the company and the offer carefully. See advertising materials for more advice. Con artists send bogus invoices for what appear to be phone directory listings or for office supplies that were never ordered or delivered, hoping that no one will check before paying them.
