A United States federal law (1991) that led to Federal Communications Commission (FCC) rules prohibiting telephone solicitation calls to a residence before 8:00 am or after 9:00 pm. Anyone making a telephone solicitation call to a residence must provide his or her name, the name of the person or entity on whose behalf the call is being made, and a telephone number or address at which that person or entity may be contacted.The TCPA specifically mentions automatic telephone dialing systems, or auto dialers, and prerecorded messages, and includes rather substantial penalties for telemarketers found guilty of violating the privacy of residential, fax, and certain other categories of users. In 2003, the FCC revised its rules implementing the TCPA and, together with the Federal Trade Commission (FTC), established a national Do-Not-Call Registry. The FCC also adopted restrictions on the number of abandoned calls that are permissible. See also Do-Not-Call Registry, FCC, and telemarketing.
