Telephone Consumer Protection Act (US)
The Telephone Consumer Protection Act of 1991 makes it unlawful for any person to use a computer
or other electronic device, including fax machines, to send any message unless such message clearly
contains, in a margin at the top or bottom of each transmitted page or on the first page of the
transmission, the date and time it is sent and an identification of the business, other entity, or
individual sending the message and the telephone number of the sending machine or such business,
or other entity, or individual. (The telephone number provided cannot be a 900 number or any other
number for which charges exceed local or long distance transmission charges).
