If you registered your phone numbers with the national Do Not Call registry, keep in mind that the registration is good for five years. Next year many of the earliest registrations in the list will begin to expire.

You do not need to wait to renew your registration but can do so at any time. The registration is then good for five years from the point of registration. It's worth renewing early because if there is any gap in the registration, telemarketers will be able to seize on that brief lapse to start calling you again.
