Add your phone number to the "National Do Not Call Registry" created by the U.S. government. Register online at donotcall.gov or by calling 1-888-382-1222 from the phone you want added to the list. Adding your number to the list is free and is good for five years, after which you will need to add your number again.
Do not give your number to companies and businesses or print your phone number on checks, unless it is necessary. In situations where you must give your phone number, ask them to not share it with other companies and telemarketers.
Answer toll-free calls and tell them to add your phone number to their "Do Not Call" list, which the Federal Telephone Consumer Protection Act of 1991 requires companies to maintain. Your phone number will stay on their list for 10 years. Nonprofit organizations are exempt from this law.
Block your number from being displayed on caller IDs by dialing *67 before placing a call. This feature does not work when dialing 1-800 or 1-900 numbers.
