Southampton has sent ships to every ocean from its docks, and a 023 number tells customers your business is rooted in a city that trades with the world.
Calls to your 023 Southampton phone numbers can be answered on a mobile, a handset or a laptop, and our UK-based team goes on looking after the number once it is running.
If you hold numbers already, we can move them across without fuss, and fresh ones are on offer as well. What do 023 Southampton phone numbers give a business?
Marine suppliers, researchers and retailers all use 023 Southampton phone numbers. Anyone who also needs handsets and apps can read about a complete system on our business phone system in Southampton page.
Our VoIP phone systems page explains how apps and handsets can sit alongside a Southampton number.
Southampton combines one of the busiest ports in Britain with the Ordnance Survey, the University of Southampton and a large marine and engineering sector. 023 Southampton phone numbers put a firm in that company, from a start-up at Ocean Village to a supplier in Eastleigh.
Shipping agents, cruise suppliers and marine engineers work near the docks, researchers around the university and the oceanography centre, and professional firms near Southampton Central. A local number lets you serve all of them from any desk.
New ventures often take 023 Southampton phone numbers before they sign a lease, and firms in Portsmouth or Winchester add one to reassure customers on the south coast.
On a lorry heading to the docks, a brochure at the boat show or a card handed out at West Quay, a 023 number reaches Southampton and Hampshire without an office in the city.
The 023 area code covers Southampton and its neighbours, including Eastleigh, Totton and Hythe. The code is shared with Portsmouth, and around Southampton it takes in the city centre, the docks and districts such as:
Winchester, Romsey, Fareham and Lymington fall outside 023 and keep codes of their own. Give us an address and we will confirm which code belongs to it.
A 023 number can ring a team in Winchester or a home worker in the New Forest just as readily as an office near the docks, and callers across these districts recognise the code.
For handsets, apps and a complete phone system, see our business phone system in Southampton page.
Southampton and Portsmouth share one geographic code, 023, followed by eight digits, and the first digits after it show which city a number belongs to. Below are the dialling rules and the nearby places that use different codes.
Dial 023 and the eight digits after it, for example 023 8xxx xxxx. Landlines, mobiles and apps all follow the same pattern.
Callers abroad dial +44 23 and the eight digits, dropping the zero that opens the area code.
Winchester uses 01962, Romsey 01794, Fareham 01329, Lymington 01590 and Bournemouth 01202. We can arrange numbers for those places too.
If you would like a 023 number together with another one, tell us and they can share routing.
