The National Do Not Call Registry gives you a choice about whether to receive telemarketing calls

• You can register your home or mobile phone for free.
• After you register, other types of organizations may still call you, such as charities, political groups, debt collectors and surveys. To learn more, read our FAQs.
• If you received an unwanted call after your number was on the National Registry for 31 days, report it to the FTC.

Add both ways – as a 10 digit number, and again as 11 digits with a leading 1.

11 is the standard, but sometimes we don’t think about it that way.
