In order to combat burgeoning problems with pay per call services, the Federal Trade Commission (FTC) passed the Telephone Disclosure and Dispute Resolution Act (TDDRA) in 1993. This act sets specific requirements for advertising and operating 900 number services to prevent deceptive billing practices.

For example, all numbers that cost more than $2 per call are legally required to warn callers about these charges during the introduction, or preamble. Callers should be allowed the opportunity to hang up without being charged when calling these numbers.

Any service bureau you use should be able to guide your firm through the specifics of the Act to ensure that your 900 program is in compliance.
