A Southampton 023 number that signals you belong in the UK's maritime and cruise logistics heartland

Southampton has a population of around 270,000 in the city and anchors a South Hampshire conurbation of roughly 880,000 people, which makes it one of the UK’s largest maritime and logistics hubs. A 023 number is the single clearest signal to UK customers that your company operates in Southampton rather than further afield.

Whether you run a cruise line operations office from Ocean Village, a logistics firm near the port, or a technology company at Southampton Science Park, a 023 number ties your branding to Southampton without you having to lease a waterfront office. CallFactory delivers the number together with a full cloud phone system, so there is no on-site hardware to install and your existing handsets, mobiles and softphones keep working.

The 023 area code was introduced in 2000 under Ofcom’s Big Number Change, which consolidated the original 01703 (Southampton) and 01705 (Portsmouth) codes into a single 023 zone covering the entire South Hampshire Solent region. Southampton numbers were allocated the 023 80xx xxxx, 023 81xx xxxx and 023 82xx xxxx ranges, whilst Portsmouth received 023 92xx xxxx and 023 93xx xxxx. This consolidation reflected the integrated geography of South Hampshire and recognised strong maritime, logistics and aerospace connections across both cities.

The 023 area maps onto the South Hampshire and Portsmouth telecoms region, which means porting between providers is straightforward — any UK carrier that holds 023 stock can release a number to CallFactory through the standard gaining-provider-led process.

Area code 023 covers Southampton and a wide South Hampshire commuter belt. Major centres inside the area include:

• Southampton City Centre — banking, insurance, professional services and retail
• Ocean Village — Carnival UK headquarters (P&O Cruises, Cunard, Princess, Holland America), waterfront retail and hospitality
• Town Quay and Cruise Terminals — Associated British Ports, UK’s busiest cruise port, ferry operations
• Port of Southampton — UK’s second-busiest container port, vehicle export terminal
• Southampton Vehicle Terminal — Britain’s busiest car export facility (Jaguar Land Rover, Ford, Mini)
• University of Southampton — Highfield Campus and Waterfront Campus, Russell Group
• Southampton Science Park — Chilworth, photon science and advanced technology
• Eastleigh — suburban and light industrial areas, Solent Airport
• Chandler’s Ford — residential and business parks
• Totton and Hedge End — suburban areas on the 023 fringe

If your business is registered at any Southampton or South Hampshire postcode, you qualify for a 023 number.

Southampton is broad, so a 023 number suits a wide mix of sectors. The three profiles we see most often at CallFactory are:

Maritime, cruise and logistics — The Port of Southampton is the UK’s busiest cruise port and second-busiest container terminal, whilst Carnival UK operates the world’s largest cruise brands (P&O, Cunard, Princess, Holland America) from Ocean Village. A 023 signals alignment with that global maritime ecosystem, which reduces friction in procurement for shipping lines, logistics operators and cruise operators.

Higher education and research — University of Southampton is a Russell Group institution with world-leading oceanography and aerospace research, generating a steady pipeline of talent across maritime, supply chain and advanced manufacturing. A 023 attracts student enquiries and B2B research partnerships.

Automotive and aerospace logistics — Southampton Vehicle Terminal is Britain’s busiest car export port, handling Jaguar Land Rover, Ford and Mini exports. Combined with aerospace heritage at Lee-on-the-Solent nearby (Gosport), a 023 signals expertise in that heavy-transport supply chain.

Outside those three profiles a 023 still pays off. Healthcare practices, online retailers, hospitality and membership organisations across Southampton all see the same local-trust benefit.

Google treats your business phone number as a geographic signal, which means a 023 number on your website, your Google Business Profile and UK business directories tells Google that your company belongs to Southampton. Combined with a consistent NAP (Name, Address, Phone) profile across listings, that strengthens your ranking for searches such as “accountant Southampton”, “logistics Southampton” or “cruise operations Solent”, and improves visibility on Google Maps.

Write the 023 number in the same format everywhere — same spacing, same separators — because Google only links citations together when they match. CallFactory uses the Ofcom-recommended format 023 XXXX XXXX, so you can copy it into every listing without introducing variations.

Southampton-based online retailers frequently report a lift in phone enquiries once they display a 023 number alongside a mobile or 0800 line. A 023 reads as local, established and maritime-savvy, so customers hesitate less before dialling, which is especially valuable for higher-value purchases where a quick conversation closes the sale.

For professional services firms — legal, financial, creative, consulting — the 023 works as a trust marker on LinkedIn posts, email signatures and Google Ads. You can split inbound calls between the 023 and any other numbers you run, which lets you attribute leads to the marketing channel that generated the call.

If you already hold a 023 number with another UK provider, we can port it across at no cost. You keep the existing number and gain the CallFactory feature set — call queues, recording, analytics, IVR — on top of it. Porting itself takes up to five working days and we schedule the cut-over for a date that works for you, which keeps your line live until the moment the number transfers.

If you would rather pick a fresh, unused 023 number — perhaps one with a memorable digit pattern in the 023 80 or 023 81 Southampton range — the number picker at the top of this page shows live availability. We hold stock across the full 023 range so you can choose whichever reads best for your brand.

Many Southampton businesses run a 023 alongside another number. Common combinations include:

• 023 + 07 — the 023 on the website and in advertising, a 07 mobile for existing clients who want direct contact. Forwarding from the 023 to a mobile is included by default.
• 023 + 0333 — the 023 for local customers and a national 0333 number for UK-wide enquiries at standard geographic rates. Both lines land in the same call flow.
• 023 + 0800 — the 023 for general reachability and a 0800 freephone number for sales hotlines or campaigns, so callers dial at no cost while you cover the inbound minutes.

All combinations run on a single CallFactory account. Current rates for additional numbers are listed on the pricing page.

A Southampton 023 number contains 11 digits in total: the area code 023 followed by an 8-digit subscriber number.

Standard format: 023 XXXX XXXX (Southampton numbers typically start 023 80, 023 81 or 023 82)

Use the same format everywhere — your website, Google Business Profile, invoices and directories — because identical formatting is what allows search engines to tie your listings together.

The 023 number is part of your CallFactory business plan. There are no connection fees and no setup charges. The plan price depends on which features you activate — IVR, call queues, voicebots, call recording — and whether you pay monthly or annually, since the annual plan is cheaper per month. If you need several 023 numbers, for example one per department or terminal, we add them to the same account.

All monthly contracts come with a one-month notice period. Every feature, plan and rate is listed on the pricing page.
