023 Portsmouth Phone Numbers

Portsmouth is home to the Royal Navy and a harbour city that has always looked outward, and a 023 number tells customers your business is part of that tradition.

Whichever handset, mobile or laptop you favour can pick up a 023 Portsmouth phone number, and a UK-based team remains on hand once the calls start arriving.

Defence suppliers, hoteliers and tradespeople on Portsea Island all depend on 023 Portsmouth phone numbers. Should you want desk phones and apps too, our business phone system in Portsmouth page sets out a complete system.

Handsets and apps can work alongside a Portsmouth number, and our VoIP phone systems page shows how.

Why Portsmouth Businesses Choose a Local Number

Portsmouth Naval Base, the Historic Dockyard, the ferry port and the university give the city a mix of defence, marine engineering, tourism and education.

023 Portsmouth phone numbers connect a firm to that mix, and they suit a company in Havant as well as one at Gunwharf Quays.

Defence suppliers work around the base and the international port, creative and digital firms around Southsea and Albert Road, and professional teams near Cosham and Port Solent. A Portsmouth number lets you answer each of them from wherever you are.

Firms often take 023 Portsmouth phone numbers before choosing premises, and businesses in Southampton or Chichester add one to appear local across Portsea Island and the harbour.

A 023 number on a van at Fratton, a flyer from Southsea or a stand at a seafront event brings in calls from Portsmouth and the Solent without an office on Portsea Island.
