The National DoNotCall Registry
Within the next few week, all cell phone numbers will be made public to telemarketers. This means you'll start receiving those annoying phone calls asking if you want to buy something stupid, like an erasable permanent marker or something. This is where the National DoNotCall Registry line comes in. By dialing 1-(888)-382-1222 and following the simple directions, your phone number can be entered onto the list and it will become illegal for most telemarketers to contact you after about 31 days. You must call on the phone you wish to block, and you can turn in any telemarketer that contacts you after 31 days of your number being on the list by calling the number again.
Again, the number is 1-(888)-382-1222.
