The business advantages of a local geographic number
Calls to 023 numbers cost the same as calling any other 01 or 02 number, and may be free within the caller's call package. No premium surcharges, no surprises.
A 023 number signals an established business with a genuine Southampton presence. Local customers are far more likely to call and trust a recognisable Southampton area code than an unfamiliar or out-of-area number.
A 023 number gives your business a recognisable Southampton point of contact while you answer calls from anywhere. Route incoming calls to different locations based on time of day or team availability.
Unlike a traditional landline tied to a single exchange line, your virtual 023 number travels with your business. Move offices, change providers, or expand beyond Southampton without ever losing your number.
All UK 023 geographic numbers are regulated by Ofcom. You have the legal right to port your 023 number to any provider at any time.
