Which regulation allows consumers to permanently list their numbers to prevent marketing calls?

The Do Not Call Improvement Act is the regulation that empowers consumers to permanently list their telephone numbers in a directory that helps prevent unsolicited marketing calls. This Act builds on the foundation laid by the original Do Not Call registry established to provide consumers with a straightforward option for avoiding telemarketing calls. By allowing consumers to register their numbers permanently, this regulation enhances consumer privacy and choice in managing unwanted communication from telemarketers.

In the context of the other choices, the Telemarketing Sales Rule provides specific guidelines for telemarketers but does not specifically address the permanent listing of numbers. The Telephone Consumer Protection Act primarily focuses on regulating automated calls and text messages, but it does not establish a permanent registry for consumers. The Consumer Privacy Act, while relevant to privacy issues, does not specifically deal with telemarketing or the Do Not Call registry. Thus, the correct regulation that specifically allows for the permanent listing of consumer numbers to limit marketing calls is the Do Not Call Improvement Act.
