What is the role of a toll-free telephone number in the opt-out process?

The role of a toll-free telephone number in the opt-out process is primarily to provide consumers with a convenient and accessible means to exercise their opt-out rights. This service ensures that individuals can easily communicate their preferences regarding the use of their personal information, particularly in relation to marketing and promotional offers. By allowing consumers to call in without incurring charges, it lowers the barrier for them to take action on their privacy choices, which is essential for an effective opt-out process.

In contrast, the other options do not focus specifically on the opt-out mechanism. While promotional offers, customer service inquiries, and complaints are relevant topics, they do not pertain to the core functionality that a toll-free number plays in facilitating the exercise of opt-out rights. The emphasis is on providing consumers with the tools they need to protect their privacy, making the toll-free number a vital part of the opt-out process.
