What Is a Virtual UK Business Phone Number, Exactly?
A virtual UK phone number is a real, dialable number — with a proper 01, 02, 07, or 0800 prefix — that routes calls over the internet instead of a physical phone line. No SIM card, no desk phone, no BT OpenReach engineer needed. Anyone in the world can call it, and it rings wherever you point it: your browser, a softphone app, or a forwarding number.
Here's what most people miss: the caller has no idea it's virtual. They see a London 020 number or a Manchester 0161 and dial it like any other UK number. You answer in Berlin, Bangalore, or Brooklyn.
The number itself is hosted by a VoIP provider who leases it from a UK telecoms regulator-approved carrier. You manage routing, voicemail, and team access through a dashboard.
There are four main UK number types worth knowing:
- Geographic numbers (01/02): Tied to a city or region — 020 for London, 0121 for Birmingham, 0161 for Manchester. These feel local and familiar to UK callers.
- National rate (03x): Non-geographic but cost callers the same as 01/02. Good for UK-wide businesses.
- Freephone (0800/0808): Free for callers. Useful for customer support lines. You absorb the inbound cost.
- Mobile (07x): Feels personal. Some businesses prefer these for direct client contact.
If you're aiming for credibility with UK customers, a 020 or 0161 number is your safest default.
Why UK Businesses (and Non-UK Businesses) Need One in 2026
There's a direct commercial argument here. Research consistently shows that a phone number on your website increases sales conversions — industry estimates put the lift at 20–30% for service businesses. A UK number specifically signals that you're reachable, local-ish, and serious.
Post-Skype shutdown in May 2025, many small businesses lost their makeshift "business phone" setup overnight. Microsoft migrated everything to Teams, which brings its own international calling costs that can catch you off guard. A dedicated virtual number through a VoIP provider is cleaner, cheaper, and purpose-built for this.
For non-UK companies, the use case is even clearer. A US e-commerce brand selling into the UK doesn't want to lose British customers who prefer calling before they buy. A 0800 or 020 number on the checkout page removes that friction. Pair it with a shared team balance and your whole team handles those calls without adding seats.
Already paying per seat on a legacy system? That model is quietly draining your budget. Seat-based VoIP pricing costs more than most businesses realise.
Step-by-Step: How to Set Up a UK Virtual Number with GlobCall
This takes 10 minutes or less. No credit card required to start, no annual contracts.
Step 1: Create your GlobCall account
Go to GlobCall.com and sign up. It's browser-based — nothing to download, no app install, no extension. Works on Chrome, Firefox, Safari, or Edge.
Step 2: Go to the Business dashboard
Navigate to /business. This is where you manage UK numbers, add team members, and top up your shared balance. The interface is clean. You're not wading through enterprise menus to find a simple setting.
Step 3: Choose your UK number type
Pick your prefix based on purpose:
- Selling to London clients? Get a 020 number.
- Building a national UK presence? Use 03x.
- Running a support line where you want zero friction for callers? 0800.
You can hold multiple UK numbers on one account — useful if you serve different regions or want separate numbers for sales and support.
Step 4: Add team members and set the shared balance
Here's where GlobCall differs from most. There are no per-seat fees. You add team members, they access the same account, and calls draw from one shared balance. A team of 15 pays exactly the same structure as a team of 2. How teams share one phone balance explains the mechanics in detail.
Step 5: Configure call routing
Decide where inbound calls to your UK number go. Options typically include:
- Ring a specific team member's browser
- Distribute across available team members
- Forward to a mobile number
- Drop to voicemail with a custom greeting
Set your business hours too. Calls outside those hours can route to voicemail or a secondary number automatically.
Step 6: Test your number
Call it from a UK mobile or use an online number-testing tool. Check voicemail pickup, call quality, and that your greeting plays correctly. Do this before you publish the number anywhere.
Step 7: Place the number on your website, email signature, and Google Business Profile
A virtual number only delivers return if it's visible. Your Google Business Profile matters most for local UK searches — a 020 number there supports local SEO signals too.
Outbound Calls from Your UK Number: Rates and What to Expect
Most teams don't just receive calls — they need to make them too. Calling UK landlines from your virtual number via GlobCall costs £0.03/min. That's competitive with almost any carrier add-on plan, and you're not locked into a monthly bundle you'll never fully use.
Calling internationally is where browser-based VoIP shows its real value. If your UK business regularly calls clients in the US or Canada, that's $0.02/min. Germany landlines run $0.04/min. India is $0.08/min — significantly cheaper than O2 or EE add-ons for the same route.

The pay-as-you-go model matters here. You're not guessing how many minutes you'll use and committing upfront. Top up what you need. For a full comparison against monthly subscriptions, pay-as-you-go vs monthly subscription business phone lays it out clearly.
Choosing the Right UK Virtual Number Provider: What to Compare
Not all providers are equal. Here's what to actually evaluate before committing.
Number availability and types Can you get the exact prefix you want? Some providers only offer 03x numbers and call it a "UK virtual number." That's fine for some use cases, but if you want a London 020, verify availability before signing up.
Call quality and infrastructure Quality degrades on providers that cut corners on carrier relationships. Test before you commit — most reputable providers offer trials. GlobCall offers a 60-minute free call so you can assess quality on real routes before spending anything.
Pricing model: per seat vs shared balance This is the biggest variable in total cost. A 10-person team on a $25/user/month platform costs $250/month in seat fees alone, before a single minute of calling. A shared balance model costs only what you actually use. Comparing RingCentral's international calling rates to browser VoIP makes this gap concrete.
No-download access If your team needs to install software or manage desktop apps across 15 machines, setup friction adds up fast. Browser-based means any device with a connection works. Browser-based VoIP explained covers why this matters operationally.
Number portability Can you bring an existing UK number to the platform? Porting usually takes 5–10 business days in the UK. Good providers handle this without extra fees.
Common Mistakes to Avoid When Setting Up a UK Virtual Number
Setup is straightforward. Maintaining it well is where people trip up.
Publishing the number before testing it. Seems obvious. Still happens constantly. Call the number from three different devices before it goes live anywhere.
Skipping voicemail configuration. An unanswered call with dead silence — no voicemail prompt — tells callers the number isn't real. Set up a proper greeting even if it's just 15 seconds.
Using only one team member as the recipient. If your single assigned person is in a meeting, calls drop. Route to a group, not an individual.
Ignoring call analytics. Most VoIP dashboards show peak call times, missed call rates, and average call duration. Check this monthly. It tells you whether your routing setup is actually working.
Choosing a provider with hidden per-minute fees on inbound calls. Some platforms charge you to receive calls on your virtual number. Read the small print. With GlobCall, inbound calls to your UK number are included.

Frequently Asked Questions
Can I get a UK virtual number if my business isn't registered in the UK?
Yes. You don't need a UK company registration, a UK address, or any physical UK presence. You'll need to verify your identity (standard KYC), but the number can be issued to an international individual or business. This is specifically why non-UK companies use virtual numbers — to build a UK-facing presence without incorporation costs.
How long does it take to get a UK virtual number active?
In most cases, under 10 minutes for a new number. Number porting — transferring an existing UK number from another provider — typically takes 5–10 business days, depending on your current carrier's processes.
Will callers know it's a VoIP number?
No. A 020 number looks and behaves like any other 020 number to the caller. There's no "VoIP" label on their screen. Call quality on good providers is indistinguishable from a traditional line.
What happens to my UK number if I don't top up?
Most providers suspend inbound routing — callers get a "number not available" message — rather than cancelling the number immediately. You typically have a grace period (often 30–90 days) to top up before the number is released. Check your provider's specific policy.
Can I use a UK virtual number for WhatsApp Business?
You can, but with caveats. WhatsApp verification requires receiving an SMS or call to the number. Some virtual numbers support SMS; some don't. Check specifically whether your provider's UK numbers support SMS before attempting WhatsApp registration. How virtual numbers work with WhatsApp goes into the specifics.
