You don't change a number, so pick one that sticks
It will sit in the phone of every customer, patient or client who calls you back. That's why the numbers that are easy to remember and pass on come first, rather than the next one in the range.
The number comes with the plan
You pay for the people you add to the number, not for the number itself and not for the handsets.

Why a 01865 number means something here
Oxford runs one of the densest knowledge economies in Europe: a university that consistently ranks top in the world, a life-sciences cluster that produced the Oxford-AstraZeneca vaccine, Oxford University Press and a ring of science and business parks that host hundreds of spin-outs and scale-ups. Add the BMW MINI plant at Cowley and seven million annual visitors, and the commercial mix is unlike anywhere else in Britain. A 01865 number is the single clearest signal to UK customers that your company operates in this knowledge capital.
Whether you run a biotech spin-out on the Science Park, a clinic near the Headington hospitals, a tutoring or edtech venture in the centre or a professional practice in Summertown, a 01865 number ties your branding to Oxford without you having to lease some of the most expensive office space outside London.
Google treats your phone number as a location signal. A 01865 number on your website, your Google Business Profile and in business directories tells Google that your business belongs to Oxford, as long as you write it the same way everywhere, with the same spacing and separators.
Area code 01865 covers Oxford and a ring of surrounding towns and villages.
Frequently asked questions about Oxford 01865 numbers
Usually within one working day. We check your business details — most checks clear the same morning — and after that the number is live and ready for calls. You don’t need new handsets or a SIP phone to get started, because calls can be routed straight to your existing mobile, landline or desktop app.
Yes. The 01865 number is registered on your own business address, which can be anywhere in the UK or abroad, and not on where individual staff happen to be sitting. Remote workers in Abingdon, Bicester or further afield can answer calls on the same 01865 line through the CallFactory app or any SIP handset, so customers still see a single Oxford point of contact.
Yes. Porting a working 01865 number is free and typically takes up to five working days once your losing provider releases the number. We schedule the cut-over on a date that suits you, which means your line stays live right up to the moment the number moves across. Read more on the porting page.
A 01865 number is a standard UK geographic number, so callers pay their normal landline rate and the call comes out of the inclusive minutes on virtually every UK mobile and landline plan. For most of your customers that means calling you is effectively free — one of the reasons a local number outperforms premium and non-geographic alternatives for inbound enquiries.
Plenty of Oxford businesses do exactly that. The 01865 attracts customers in Oxfordshire, while a national 0333 number covers enquiries from the rest of the UK at standard geographic call rates. Both numbers land in the same IVR and hunt group, so your team handles them without thinking about which line rang.
The 01865 area spans Oxford together with a ring of surrounding towns and villages, which means the city centre, Headington, Cowley, Summertown, Botley, Kidlington, Wheatley, Eynsham, Yarnton and Marston. That includes business locations such as the Oxford Science Park and Oxford Business Park, the Headington hospital quarter (John Radcliffe, Churchill), the BMW MINI plant at Cowley and the university and publishing district in the centre. Note that Abingdon (01235) and Bicester (01869) use their own codes.
Oxford dialled 0865 until 16 April 1995, when the PhONEday renumbering added a 1 to every UK geographic code and created 01865. Oxford’s exchange history runs deep — the university and publishing houses were early heavy telephone users — and the numbering area still follows the city’s commuter geography. Porting between providers is straightforward — any UK carrier that holds 01865 stock can release a number to CallFactory through the standard gaining-provider-led process.
Yes. Callers outside the UK simply dial +44 1865 followed by your subscriber number, dropping the leading zero. For Oxford businesses with international students, researchers or publishing clients, that matters more than in most cities — overseas callers reach you exactly as they would any British landline.
The 01865 number itself is included with every plan: you pay per plan, not for the number and not for the handsets. Business Number is £130 a year for one person, Phone System £22 a month for a team of up to two and Customer Service £43 a month for up to eight. Shared handsets, such as the phone on reception or in the waiting room, never count. There are no setup fees and no hidden charges; full details are on our pricing page.
Yes. Our text-to-speech assistant generates a professional greeting in English or any other supported language, which means you can change the wording at any time without a studio. A choice menu — press 1 for sales, 2 for support — comes with Customer Service and takes a few clicks to set up.
Popular choices are numbers that are easy to remember and pass on, such as a round hundred or thousand at the end, four repeated digits or a run that counts up. The number picker on this page puts those at the top, and the Easy to remember tab shows only them, each with the reason it sticks. What you see there is what is available right now.
Yes. Many Oxford businesses run a 01865 for general reachability and a 0800 freephone number for admissions lines, bookings or campaigns, so callers dial at no cost while you cover the inbound minutes. Both numbers land in the same call flow on a single CallFactory account.
