028 area code

Northern Ireland

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

Numbers are normally allocated regionally, with the first digits of the local number indicating the approximate area:

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

Phone number formatting examples:
Wrong: 02890 320202 028 90 320202 (02890) 320202	Right: (028) 9032 0202 028 90320202 028 9032 0202

For overseas callers, use the style: +44 28 xxxx xxxx

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

The 028 area code has existed since April 2000.

1995	Northern Ireland uses a variety of local area codes of different lengths in the format (01xxx) and (01xxxx). Local numbers are either 5 or 6 digits long, depending on the area.
2000	All local area codes are withdrawn within Northern Ireland, with landline numbers standardised at eight digits long and a single area code of 028.
