028 area code

Northern Ireland

UK area code 028 covers the whole of Northern Ireland including Belfast.

The first two digits of the eight-digit local number indicate where in Northern Ireland it is associated with:

For example, (028) 4461 0801 would be in Downpatrick, while (028) 9018 0018 is a Belfast number.

Local telephone numbers are 8 digits long throughout Northern Ireland. An 028 number should be displayed in the format: (028) xxxx xxxx.

When displaying an 028 phone number for international callers, it should be shown in the style: +44 28 xxxx xxxx.

Displaying 028 numbers in the correct format makes them easier to remember and dial correctly. [Reasons why...]
