You don't change a number, so pick one that sticks
It will sit in the phone of every customer, patient or client who calls you back. That's why the numbers that are easy to remember and pass on come first, rather than the next one in the range.
The number comes with the plan
You pay for the people you add to the number, not for the number itself and not for the handsets.

Why a 028 number means something here
Belfast is Northern Ireland’s economic centre, home to more than 40,000 registered businesses and the UK’s largest concentration of cybersecurity firms, fintech startups and aerospace engineers. A 028 number is the single clearest signal to UK customers that your company operates in Northern Ireland’s capital rather than elsewhere.
Whether you run a cybersecurity firm in Titanic Quarter, a fintech startup in Citi Belfast’s 3,000-person campus, a legal practice in Cathedral Quarter, an aerospace supplier working with Spirit AeroSystems or a media company producing Game of Thrones at Titanic Studios, a 028 number ties your branding to Belfast without you having to lease expensive prime real estate.
Google treats your phone number as a location signal. A 028 number on your website, your Google Business Profile and in business directories tells Google that your business belongs to Belfast, as long as you write it the same way everywhere, with the same spacing and separators.
Area code 028 covers the whole of Northern Ireland.
Frequently asked questions about Belfast 028 numbers
Usually within one working day. We check your business details — most checks clear the same morning — and after that the number is live and ready for calls. You don’t need new handsets or a SIP phone to get started, because calls can be routed straight to your existing mobile, landline or desktop app.
Yes. The 028 number is registered on your own business address, which can be anywhere in the UK or abroad, and not on where individual staff happen to be sitting. Remote workers in Lisburn, Bangor or elsewhere across Northern Ireland can answer calls on the same 028 line through the CallFactory app or any SIP handset, so customers still see a single Belfast point of contact.
Yes. Porting a working 028 number is free and typically takes up to five working days once your losing provider releases the number. We schedule the cut-over on a date that suits you, which means your line stays live right up to the moment the number moves across. Read more on the porting page.
Plenty of Belfast businesses do exactly that. The 028 attracts customers in Northern Ireland, while a national 0333 number covers enquiries from the rest of the UK at standard geographic call rates. Both numbers land in the same IVR and hunt group, so your team handles them without thinking about which line rang.
The 028 area covers the whole of Northern Ireland, so a 028 number is shared across Belfast, Lisburn, Bangor, Newtownards, Carrickfergus, Armagh, Newry, Derry/Londonderry, Ballymena, Enniskillen and every other part of the province. This unified code is relatively new — it was introduced in 2000 to consolidate 22 separate Northern Ireland area codes into one, so porting between providers is straightforward.
The 028 code was introduced in 2000 under the Big Number Change, when Ofcom unified 22 separate Northern Ireland area codes (including 01232 for Belfast, 01247, 01265 and others) into a single 028 range. That consolidation was one of the UK’s most ambitious area-code reforms. Any UK carrier that holds 028 stock can release a number to CallFactory through the standard gaining-provider-led process.
Yes. Every postcode in Northern Ireland falls under the same 028 code, so a business registered in Lisburn, Bangor, Armagh or anywhere else in the province gets a 028 number rather than a different regional code. That means customers read 028 as “Northern Ireland” regardless of which town or city your office is in.
Popular choices are numbers that are easy to remember and pass on, such as a round hundred or thousand at the end, four repeated digits or a run that counts up. The number picker on this page puts those at the top, and the Easy to remember tab shows only them, each with the reason it sticks. What you see there is what is available right now.
The 028 number itself is included with every plan: you pay per plan, not for the number and not for the handsets. Business Number is £130 a year for one person, Phone System £22 a month for a team of up to two and Customer Service £43 a month for up to eight. Shared handsets, such as the phone on reception or in the waiting room, never count. There are no setup fees and no hidden charges; full details are on our pricing page.
Yes. Our text-to-speech assistant generates a professional greeting in English or any other supported language, which means you can change the wording at any time without a studio. A choice menu — press 1 for sales, 2 for support — comes with Customer Service and takes a few clicks to set up.
