Region vs. Telephone Area
UK geographic codes vary in length and represent telephone numbering areas, not administrative borders or live caller locations. Portability, forwarding and internet telephony can separate a number from its original area or network. The +44 arrangement also covers Jersey, Guernsey and the Isle of Man, which are Crown Dependencies and not part of the United Kingdom.
A code listed beside a city reflects the featured numbering association; it does not assert that every community in Northern Ireland uses that code or that the code stops at the administrative border.
