Since the Do Not Call registry began in June 2003, millions have signed up to keep telemarketers from calling them.

However, many don't realize that the signups only last for five years.

To keep telemarketers at bay, consumers are urged to re-register by calling 888-382-1222 or by going to www.donotcall.gov.

Telemarketers will have 31 days to remove personal phone numbers from their lists.
