Calls from telemarketers can be an aggravating and annoying interruption. Unfortunately, for every hundred people that hang up when a telemarketer calls, there are a couple people that listen and actually buy the products being offered, further perpetuating the intrusive sales technique. The public outcry against telemarketers has grown so strong, that the government created a national "do not call registry," which can help individuals gain some privacy from telemarketers.

  1. 1

    Register your phone or phones on the national "do not call" list. To begin, go the government's "do not call" registry website, ( and click "register now." Enter the basic information in the required fields along with the phone numbers you want to register and your e-mail address. After submitting the phone numbers, an e-mail will appear from the do not call registry. Open the email and follow the directions to complete your registration. It can take up to a month for your phone number to fully permeate the registry to all telemarketers.

  2. 2

    File complaints against further telemarketing. Despite the noble intentions of the "do not call" registry, it cannot ensure complete blockage of all telemarketers. If you receive telemarketing calls after signing up to the registry, file a complaint against the telemarketer through the "do not call" website. You must have been on the list for 31 days to file a complaint. Be able to give the date of the call and either the name or phone number of the telemarketing company. Companies of which you are a customer cannot be considered telemarketers.

  3. 3

    Use caller ID to screen against telemarketers. Even with your best efforts, a few telemarketers are likely to slip through the cracks from time to time. Using a caller ID system can allow you to avoid having to talk to telemarketers, by never answering the phone when an unknown number contacts you. Furthermore, caller ID will display the phone numbers of incoming calls, allowing you to more easily report telemarketers.

Tips and warnings

  • Telemarketers are not allowed to call cell phones, since many cell phone plans involve payment by the minute. Still, an occasional telemarketing call may come to a cell phone. Therefore it can be worth registering a cell phone on the national do not call list, if only to file complaints if a telemarketer calls you.
