Get a local 023 telephone number for your business and give customers a familiar South Coast number to call. Our virtual 023 numbers route calls to your mobile, existing landline or VoIP phone system anywhere in the UK — no office, engineer visit or new hardware required — and cover both Southampton and Portsmouth, sharing one area code.
Your virtual 023 number isn't tied to a particular desk or phone. Calls can be routed to your mobile, landline or VoIP system wherever you're based — whether you're a sole trader, a national business opening a South Coast territory, or a remote team serving Hampshire customers. No hardware, no engineer visit, no need to relocate.
A local telephone number is one of the simplest ways to appear established across Southampton and Portsmouth — and one of the most common reasons businesses come to us for a South Coast number specifically.
A local 023 number gives customers a familiar South Coast number to call, even if your team works from a different city entirely. Southampton and Portsmouth together are home to more than 450,000 people — a local prefix can help customers recognise your business as serving the South Coast market.
Whether you need a single new telephone number to test the South Coast market, or want to bulk buy a batch of local 023 phone numbers for a distributed sales team, T2K provisions numbers with routing live within 24 hours of ordering.
A local 023 number isn't tied to a desk phone or a Southampton address — it's hosted in the cloud and routes calls to wherever your business actually is.
Choose an available 023 number, tell us where you'd like calls routed — your mobile, an existing landline, or a VoIP system — and we'll have it live within 24 hours.

A 023 telephone number is available for use anywhere, but is traditionally associated with these SO and PO postcode areas across Southampton and Portsmouth. Southampton numbers typically start 023 8, Portsmouth numbers 023 9 — both are the same 023 area code. Note that other Hampshire towns have their own separate area codes — ranges below are indicative rather than an exhaustive list, so get in touch if you'd like us to confirm coverage for a specific postcode.
