Buy a Virtual UK Phone Number

This page is for businesses that need a professional UK phone number — whether you are a startup looking for your first business line, an established company adding a dedicated sales or support number, or an international business that wants a local UK presence. A virtual UK phone number lets you separate business and personal calls, present a professional image, and route calls to any device or team.

A dedicated business number signals credibility. Customers, suppliers and partners expect to see a recognisable phone number on your website, invoices and email signatures. A mobile number can work when you are starting out, but as your business grows, a proper business number makes a difference. It tells people you are established, reachable and serious about what you do.

CallFactory offers three types of business numbers, each designed for a different purpose. Choose the one that fits your business — or combine them to cover all your needs.

An 0808 number is free for anyone calling from a UK landline or mobile. It removes the cost barrier completely, which makes it ideal for customer service lines, helpdesks, sales enquiries and any situation where you want to make it as easy as possible for people to pick up the phone.

Toll-free numbers are not tied to any geographic area, so they work well for businesses that serve customers across the whole of the UK. Callers see the 0808 prefix and immediately understand that the call will not cost them anything. That recognition drives higher call volumes and better customer engagement.

A 0333 number is a non-geographic business number that costs the same as calling a standard landline. For most callers with inclusive minutes on their mobile plan, calls to 0333 numbers are included at no extra charge. This makes 0333 a popular choice for businesses that want a single UK-wide number without the cost of a toll-free line.

The 0333 prefix is modern and professional. It is increasingly used by government services, NHS helplines and major companies because it strikes the right balance — affordable for the caller, cost-effective for the business. It is particularly well suited for sales lines, booking lines and general enquiry numbers.

A local geographic number carries a recognisable area code that tells callers exactly where you are — or where you want to appear to be. A 020 number says London. A 0161 says Manchester. A 0131 says Edinburgh. For businesses that serve specific regions, a local number builds trust and signals commitment to that community.

We offer local numbers in over 20 UK cities, including London, Manchester, Birmingham, Edinburgh, Glasgow, Leeds, Liverpool, Bristol, Cardiff, Belfast, Sheffield, Newcastle, Brighton, Southampton, Portsmouth, Coventry, Leicester, Reading, Bournemouth, Middlesbrough, Stoke-on-Trent and Sunderland. Each number forwards to your existing phone — landline, mobile or VoIP — so you can present a local presence without needing a physical office in every city.

0808 toll-free — Best when you want maximum inbound calls and zero cost for the caller. Customer service, support desks, complaint lines, charity helplines. Removes all friction for people who need to reach you.

0333 national — Best for a single UK-wide number at standard rates. Sales lines, booking lines, general enquiries. Professional, modern, and included in most mobile call plans.

Local geographic — Best for regional credibility. Estate agents, solicitors, accountants, tradespeople, regional offices. Tells callers you are local to their area.

Many businesses combine two or three types. A 0808 for customer support, a 0333 for sales, and a local London number for the head office — all managed from one dashboard, all forwarding to the same team or to different departments.

You choose your business number type and tell us where to forward calls. We activate the number and configure it according to your needs. When someone dials your number, the call routes through our network and reaches you on your existing phone — landline, mobile or VoIP. No new hardware, no new SIM card, no installation.

You manage everything through your online account: change forwarding destinations, set opening hours, configure a phone menu with multiple options, enable voicemail, or set up sequential ringing across your team. We handle the technical setup — 90% of our customers prefer us to program the system so they can focus on answering calls and running their business.

If you already have a business number and want to move it to CallFactory, we can port it. The process typically takes five working days for business numbers. Your number stays the same — your customers will not notice any change — but you gain access to our full feature set: call forwarding, phone menus, voicemail, statistics and more.

This is particularly useful if your current provider is discontinuing analogue or ISDN lines. Instead of losing your established number, make it a virtual number with CallFactory and keep it working on any device.

CallFactory has been providing business phone numbers since 2000. Established in the Netherlands with Dutch management, we serve thousands of businesses across multiple regions and Europe. Our platform handles millions of call minutes each year, and our network is built for reliability and call quality.

We are not a reseller — we operate our own infrastructure and manage carrier relationships directly. When you need support, our team is available by phone and email. We configure your system for you, so you do not need any technical skills to get started.

UK telecommunications is regulated by Ofcom (Office of Communications). CallFactory is a notified operator with Ofcom, meaning we are registered directly with the UK regulator to provide electronic communications services. All UK phone numbers — toll-free 0808, national 0333 and local geographic — are issued in compliance with Ofcom regulations and the Communications Act 2003.

All business number types accept a worldwide address.
