My brother is a rabid anti-junk mail freak. He sent me the info below, much of which I have already done and it works.
This is a good overview article and includes some alarming statistics about the amount of junk mail we produce in the US:
Direct Marketers Association do not mail list. Must be renewed every 10 years. Allows separate opt out for Credit Offers, Catalogs, Magazine Offers (this includes subscription offers, newsletters, periodicals and other promotional mailings), and Other Mail Offers (this includes donation requests, bank offers, retail promotions and more). To permanently opt out of the credit card offers, you have to fill out a form and send via US mail, which is what I did. If you have registered before, you can login and see how much longer you have on the list before you have to re-register. When I signed in recently, close to my renewal date, it automatically renewed my opt-out for an additional 10 years, until 2030. You can include as many names for a given address as you want (e.g. You, Lois, Carol Buck, etc.)
Do Not Call Registry (for phone calls)
