At Texasnocall.com you can add your name, address and telephone number to the state-sponsored “No Call List,” which will help limit the telemarketing calls including those that use text or a graphic message or image to your residential or wireless telephone. The statewide “Do Not Call List,” will apply to any telephone marketer, including Retail Electric Providers, calling a Texas residential or wireless phone number. Your registered telephone number(s) will remain on this list for three years. The date of your registration determines the date by which all telemarketing to your number must stoop. However, there are some exceptions to the rules for telemarketers. Telemarketers may contact customers with whom they have and established business relationship; if the customer request contact; to collect a debt; or if the telemarketer is a state licensee. You can sign up at this website, and the telephone registration must be paid by credit card.
