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 023 number means something here
Portsmouth has a population of around 210,000 in the city and anchors an urban area of roughly 410,000 people, which makes it one of the UK’s leading naval and defence engineering centres. A 023 number is the single clearest signal to UK customers that your company operates in Portsmouth rather than further afield.
Whether you run a defence contracting firm near HMNB Portsmouth, a logistics operation serving the Historic Dockyard, or a technology startup at Lakeside North Harbour, a 023 number ties your branding to Portsmouth without you having to lease a waterfront office.
Google treats your phone number as a location signal. A 023 number on your website, your Google Business Profile and in business directories tells Google that your business belongs to Portsmouth, as long as you write it the same way everywhere, with the same spacing and separators.
Area code 023 covers Portsmouth and a wide South Hampshire commuter belt.
Frequently asked questions about Portsmouth 023 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 023 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 Gosport, Havant or Waterlooville can answer calls on the same 023 line through the CallFactory app or any SIP handset, so customers still see a single Portsmouth point of contact.
Yes. Porting a working 023 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 keeps your line live right up to the moment the number moves across. Read more on the porting page.
Plenty of Portsmouth businesses do exactly that. The 023 attracts customers across South Hampshire and the Solent region, 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 023 area code covers Portsmouth and a wide South Hampshire commuter belt introduced under the Big Number Change in 2000. Area 023 encompasses Portsmouth, Portsea, Southsea, Cosham, Drayton, Farlington, Hilsea, Fratton, Gosport, Waterlooville, Havant, Emsworth, Denmead and Rowlands Castle. Chichester falls outside the 023 area (uses 01243) and Fareham is on the boundary (01329). Portsmouth numbers typically start 023 92xx xxxx or 023 93xx xxxx.
Area code 023 was introduced in 2000 under Ofcom’s Big Number Change, which consolidated the original 01705 (Portsmouth) and 01703 (Southampton) codes into a single shared 023 zone covering the entire South Hampshire Solent region. Portsmouth numbers were allocated the 023 92xx xxxx and 023 93xx xxxx ranges, whilst Southampton received 023 80xx xxxx, 023 81xx xxxx and 023 82xx xxxx. This consolidation reflected the integrated geography of South Hampshire and recognised strong maritime, logistics and aerospace connections across both cities.
The 023 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.
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.
Portsmouth has a population of around 210,000 in the city and anchors an urban area of roughly 410,000 people, making it the centre of Britain’s naval and defence engineering industry. HMNB Portsmouth is home to the Royal Navy’s aircraft carriers (HMS Queen Elizabeth and HMS Prince of Wales), Type 45 destroyers and Type 23 frigates. BAE Systems Maritime Services builds and maintains the Royal Navy’s surface fleet from the historic dockyard, whilst QinetiQ operates a major defence research facility on Portsdown Technology Park. Airbus Defence & Space Portsmouth builds military radars and surveillance systems. A 023 number signals alignment with Portsmouth’s reputation for naval excellence, defence engineering expertise and maritime heritage spanning centuries.
