What it does

Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.

This bill prohibits caller identification (ID) spoofing. Under the bill, no person may knowingly transmit misleading or inaccurate caller ID information through a telephone call or text message with the intent to defraud or wrongfully obtain anything of value, including personally identifiable information. The bill also prohibits telephone solicitors from knowingly transmitting misleading or inaccurate caller ID information for any purpose, except that the telephone solicitor may transmit the name of the seller on whose behalf the telephone solicitation is placed and the seller's customer service telephone number if an individual may call that number to make a do-not-call request during regular business hours. The bill creates an exemption for transmissions in connection with authorized activities of law enforcement agencies or a court order specifically authorizing the use of caller ID manipulation. In addition, the bill prohibits a telephone solicitor from blocking the transmission of caller ID information. A person who violates any of these prohibitions is subject to a civil forfeiture of $100 to $10,000.
