To stop getting most junk mail from the U.S. Postal Service, opt out using the Federal Trade Commission's website OptOutPreScreen.com and the Direct Marketing Association's site DMAChoice.org. Alternatively, use resources available on FTC.gov to send written requests to the major consumer reporting companies and the Direct Marketing Association.
To permanently eliminate most pre-screened offers of credit and insurance, register at OptOutPreScreen.com. Registering online is the first step; you must also return a signed Permanent Opt-Out Election form, which is sent to you after you make your online request. There is also an option to opt out for only five years.
To opt out of these offers by mail, write the major consumer reporting companies a request, along with your home telephone number, name, Social Security number and date of birth. Find their addresses at Consumer.FTC.gov by clicking on the Privacy & Identity tab, clicking on the Limiting Unwanted Calls & Emails link, and then finding the Stopping Unsolicited Mail, Phone Calls, and E-mail article under the Privacy Choices header.
Register at DMAChoice.org and your name is deleted from mailing lists available to most direct-mail marketers and organizations for five years. If you do not have Internet access, mail your request plus a $1 processing fee to the Direct Marketing Association, P.O. Box 643, Carmel, NY, 10512.
