Please note that registering on the National Do Not Call List (DNCL) will not eliminate all telemarketing calls as there are some exemptions including calls made by or on behalf of certain organizations and calls made for other specific purposes:
In addition to registering on the National DNCL, you can further reduce unwanted unsolicited telemarketing calls by directly and expressly requesting that an organization place your number(s) on their internal do not call list. However people and organizations who are not telemarketing or soliciting such as those making calls solely for the purpose of market research or surveys, are not required to maintain these lists.
You should be aware that by entering a contest or signing your name on a form, you may unwittingly be providing express consent to be called. This includes filling out warranty cards, service contracts or application forms.
You can also reduce unwanted unsolicited telemarketing calls by exercising care when providing your telephone number and noting what and how your information is being used.
