2023 Assembly Bill 559 Assembly Amendment 1
2023 ASSEMBLY BILL 559
This bill prohibits caller identification (ID) spoofing, which includes a prohibition against knowingly
transmitting a misleading or inaccurate caller ID information record with the intent to defraud or
wrongfully obtain anything of value. However, this prohibition does not apply to the transmission of a
caller ID record in connection with the authorized activity of a law enforcement agency or a court order
that specifically authorizes the manipulation of a caller ID record.
ASSEMBLY AMENDMENT 1
The amendment provides that, with respect to the prohibition described above, in addition to the
exemption relating to a law enforcement activity or court order, there is an exemption for a provider of
telecommunications service, internet access service, or voice over internet protocol service, in certain
cases. This exemption applies when such a provider is engaged in any of the following:
Acting as an intermediary for the transmission of telephone service between the caller and the
recipient.
Providing or configuring a service or service feature as requested by the customer.
Acting in a manner that is authorized or required by law.
