Managing Northern Ireland telephone numbers

About this document

This document is about how we will ensure that phone companies have sufficient geographic telephone number blocks for new landlines in the 028 area code, which covers the whole of Northern Ireland.

We explain the measures that we have decided to introduce following a consultation in April 2014, which involve the allocation of smaller blocks of numbers to phone companies and making additional numbers available for Belfast and Derry/Londonderry.

We are not changing any telephone numbers or affecting existing numbers in any other way.
