The 028 code belongs to the whole of Northern Ireland, and in Belfast it tells customers that your business is part of a city with ambition, from the Titanic Quarter to the Cathedral Quarter.
Our 028 Belfast phone numbers can ring on a mobile, a desk phone or a laptop app, and a UK-based team arranges the number and supports it afterwards.
Numbers you already use can move over to us, and we can add fresh ones beside them. Here is what 028 Belfast phone numbers do for a business:
From the Titanic Quarter to Malone and Holywood, firms use 028 9 numbers. If you also want desk phones and apps, our business phone system in Belfast page covers the whole system.
Our VoIP phone systems page explains how handsets and apps work with a Belfast number.
Belfast is the economic centre of Northern Ireland, with particular strengths in cyber security, fintech, creative industries, professional services and advanced engineering.
028 Belfast phone numbers connect a business to that market, and they work as well for a firm in Lisburn or Bangor as for one in Victoria Square.
Technology and cyber security companies cluster around the Titanic Quarter and Catalyst, creative firms around the Cathedral Quarter, and legal and financial firms around Donegall Square and Laganside.
A Belfast number lets a business based elsewhere reach customers in those areas on a code they know, while your own staff answer from wherever they work.
Start-ups take a 028 Belfast number to look established before they commit to an office, and companies in Derry, Newry or Dublin add one so Belfast customers see a familiar code.
On a van on the Lisburn Road, a poster in the Cathedral Quarter or a stand at a Titanic Quarter event, a 028 number reaches Belfast and its neighbouring towns without an office in the city.
The 028 area code covers Belfast and the whole of Northern Ireland, with 9 as the first digit after it for Belfast numbers. It takes in the city centre, the Titanic Quarter and districts such as:
Numbers elsewhere in Northern Ireland, including Derry, Newry and Enniskillen, use different digits after 028. We can supply those too, and we are glad to check any address before you order.
Your 028 Belfast number can ring a team in Derry or a home worker in Enniskillen just as easily as an office on Donegall Square, and customers across the districts above will recognise it.
For handsets, apps and a complete phone system, read our business phone system in Belfast page.
All of Northern Ireland shares the 028 code, and Belfast numbers continue with 9, followed by seven digits. Here is the dialling pattern and the nearby areas outside the 028 region.
Dial 028 and then the eight digits, beginning with 9 for Belfast, for example 028 9xxx xxxx. The pattern is the same on any phone.
From abroad, dial +44 28 followed by the eight digits, and leave out the zero at the front of the code.
The Republic of Ireland uses +353, with Dublin on 01. Within Northern Ireland every town uses 028. We can supply numbers for any of them.
To have a 028 number next to one from the Republic or another UK area, tell us and we will give both the same routing.
