Junk mail lists removal services.

According to the United States Postal Service, American households receive 100.5 billion pieces of junk mail, or 868 pieces for each household each year. If you are among the many tired of receiving junk mail, help is available from some services offering to remove you from unwanted mailers' lists.
At first there is the Direct Marketing Association which last month started a tool called DMA Choice that let you choose between four categories (magazines, catalogs, credit cards, other) or individual business to allow or disallow to receive junk mail from. If you choose to opt out of a particular category or individual business mailing list, that will be good for three years.
Another opt-out service is OptOutPrescreen.com .What makes this service particular is that it removes your name only from lists that are used to send preapproved or prescreened offers of credit or insurance. It is run by the three majors credit reporting agencies (Equifax, Experian and Transunion) and Innovis. It lets you opt out for five years or permanently either online or by phone at 1-888-5 OPT OUT.
