As used in this section, the following terms shall have the following

meanings:

a. "caller identification information" means information provided by a

caller identification service regarding the telephone number and the

name of the person calling;

b. "caller identification service" means a service that allows a

telephone subscriber to have the telephone number, and, where available,

name of the calling party transmitted contemporaneously with the

telephone call, and displayed on a device in or connected to the

subscriber's telephone;

c. "pooling administrator" means the thousands-block pooling

administrator as identified in 47 C.F.R. § 52.20; and

d. "provider" means a telecommunication company that provides voice

communications services to customers in this state.

2. Consistent with authorization provided by federal law and rules of

the federal communications commission or its successors:

a. providers shall block a voice call when the subscriber to which the

originating number is assigned has requested that calls purporting to

originate from that number be blocked because the number is used for

inbound calls only; and

b. providers shall block calls originating from the following numbers:

(i) a number that is not a valid North American numbering plan number;

(ii) a valid North American numbering plan number that is not

allocated to a provider by the North American numbering plan

administrator or the pooling administrator; and

(iii) a valid North American numbering plan number that is allocated

to a provider by the North American number plan administrator or pooling

administrator, but is unused, so long as the provider blocking the calls

is the allocatee of the number and confirms that the number is unused or

has obtained verification from the allocatee that the number is unused

at the time of the blocking.

c. providers shall not block a voice call if the call is an emergency

call placed to 911.

d. providers shall not block a voice call to a subscriber who has

requested that no inbound calls be blocked.

3. For purposes of blocking calls from certain originating numbers as

authorized in this section, a provider may rely on caller identification

service information to determine the originating number.

4. Notwithstanding any other provision of law, rule, or regulation, a

voice service provider shall be considered to be in compliance with this

section and any rule or regulation adopted thereunder if such provider

has filed a certification with the federal communications commission

that the provider's traffic is either signed with STIR/SHAKEN or subject

to a compliant robocall mitigation program. A copy of such certification

shall be made available to the attorney general or the public service

commission, upon request.
