(c) the withdrawal is made for the purposes of a numbering reorganisation applicable to a particular series of telephone numbers;

(f) the allocated numbers are comprised in a series of numbers which have not to a significant extent been adopted or used during such period as may be so specified.

(4) The withdrawal of an allocation is also authorised where—

(a) the person to whom the allocation is for the time being allocated is not a communications provider; and

(b) it appears to OFCOM that contraventions by that person of numbering conditions makes the withdrawal of the allocation appropriate.

[F9 (a) in the case of a previous notification of a contravention given to that person under section 96A, OFCOM have given a confirmation decision to that person under section 96C(2) in respect of the contravention; and

(b) in the period of 24 months following the giving of that confirmation decision, one or more further confirmation decisions have been given to the person in respect of contraventions of numbering conditions;]

and for the purposes of this subsection it shall be immaterial whether the [F10 confirmation decisions] related to the same contravention or to different contraventions of the same or different conditions.

(9) In this section “numbering conditions” means—
