35 Private numbering scheme without an escape code
(1) This section applies to a private numbering scheme that does not have an escape code.
(2) If a number used in the private numbering scheme starts with “0” or “1”, the originating access carriage service provider for a call to the number must not treat the call as a call to a special services number.
(3) If a number used in the private numbering scheme starts with “2”, “3”, “4”, “5”, “6”, “7”, “8” or “9”, the number must not have more than 8 digits.
(4) Subsections (2) and (3) do not apply to a number issued to a customer if:
(a) the number was issued at the customer’s request; and
(b) before the number was issued, the carriage service provider holding the number told the customer, in writing, that use of the number in a private numbering scheme would be likely to affect the ability of end‑users in the scheme to use the number in connection with the supply of other carriage services specified in this instrument; and
(c) the number is not an access code that is specified for use with a calling number display override service; and
(d) the number is not a number that has been issued to an emergency service organisation.
