General Business (GBS) CHAPTER 20, ARTICLE 26
* § 399-z-1. Telecommunication companies blocking certain numbers. 1.
As used in this section, the following terms shall have the following

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.
