The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls at home. Most telemarketers should not call your number once it has been on the registry for 31 days. If they do, you can file a complaint at the National Do Not Call Registry Web site. You can register your home or mobile phone for free.
Placing your number on the National Do Not Call Registry will stop most telemarketing calls, but not all. Because of limitations in the jurisdiction of the FTC and FCC, calls from or on behalf of political organizations, charities, and telephone surveyors would still be permitted, as would calls from companies with which you have an existing business relationship, or those to whom you've provided express agreement in writing to receive their calls.
How to register. First, go to the National Do Not Call Registry web site.
To register, enter up to three phone numbers and your email address and click Submit. For each phone number, enter the area code in the box on the left and the rest of the number in the box on the right. Enter your email address where indicated and then click Submit. You will go to a page that lets you check that your information is correct. If your information is correct, click Register to continue the process. If it isn't, click Change to correct your information.
After you click Register, open your email. You should see a message from Register@donotcall.gov. You must open the email and click on the link in it to complete your registration. Print a copy of your registration confirmation for your records. If you do not click on the link in the email within 72 hours, your phone number will not be registered.
You can also use the above Web site to check that your phone number is on the Do Not Call list. If Congress imposes a time limit on the Do Not Call Registry, you may need to reregister on the site.
