O.C.G.A. § 46-5-171.1: Written authorization required by customer prior to being charged for service initiated by a third party.

(a) Except as provided in subsection (b) of this Code section, no telecommunications company shall charge a customer for any service which is provided to the customer by a nonaffiliated third party until such third party has certified to the telecommunications company that the third party has received the customer’s written authorization for such charges. When a customer initiates a new type of such third-party service or changes the type or types of such third-party service received, the invoice for such new or changed services must state the charges for such services in a clear, conspicuous, separate, and distinct manner so as to ensure that the customer is aware of the new or changed charges. Any telecommunications company that charges a customer for a service which is provided to the customer by a nonaffiliated third party must provide to such customer the ability to block the nonaffiliated third-party service and any charges associated with such service.

(b) This Code section shall not apply to any transaction between a customer and that customer’s selected provider of basic local exchange, inter-LATA, or intra-LATA telecommunications services or initial requests to subscribe to such services; wireless services; requests for a change in a customer’s provider of local exchange service or a change in a customer’s primary interexchange inter-LATA or intra-LATA carrier; or customer initiated use of abbreviated dialing codes or other pay-per-use services.
