§  64.1604   Prohibition on transmission of inaccurate or misleading caller
identification information.

   (a) No person or entity in the United States, nor any person or entity
   outside the United States if the recipient is within the United States,
   shall, with the intent to defraud, cause harm, or wrongfully obtain
   anything of value, knowingly cause, directly, or indirectly, any caller
   identification service to transmit or display misleading or inaccurate
   caller identification information in connection with any voice service
   or text messaging service.

   (b)Paragraph (a) of this section shall not apply to:

   (1) Lawfully authorized investigative, protective, or intelligence
   activity of a law enforcement agency of the United States, a State, or
   a political subdivision of a State, or of an intelligence agency of the
   United States; or

   (2) Activity engaged in pursuant to a court order that specifically
   authorizes the use of caller identification manipulation.

   (c) A person or entity that blocks or seeks to block a caller
   identification service from transmitting or displaying that person or
   entity's own caller identification information pursuant to § 64.1601(b)
   of this part shall not be liable for violating the prohibition in
   paragraph (a) of this section. This paragraph (c) does not relieve any
   person or entity that engages in telemarketing, as defined in
   § 64.1200(f)(10) of this part, of the obligation to transmit caller
   identification information under § 64.1601(e).
