(1) For the purposes of this Part, if a number is allocated or transferred to a carriage service provider at a particular time, the provider holds the number throughout the period:
(a) beginning at that time; and
(b) ending when:
(i) the number is subsequently withdrawn; or
(ii) the number is subsequently surrendered; or
(iii) the number is subsequently transferred from the provider to another carriage service provider;
whichever first happens.
(2) For the purposes of this section, the renumbering of a number does not affect the continuity of the holding of the number.
