What is a UK Virtual Phone Number?
A UK virtual phone number is a cloud-based +44 number that lets your business make and receive calls without a physical office or SIM card in the United Kingdom. Calls are routed over the internet via VoIP (Voice over Internet Protocol) to any device, phone, desktop, or app, from anywhere in the world.
Unlike a traditional UK landline connected to the PSTN (Public Switched Telephone Network), a virtual number is instant to set up, flexible to scale, and packed with business features like call forwarding, IVR, call recording, and SMS verification, all under one plan.
The UK’s country code +44 is assigned by the ITU (International Telecommunication Union). UK numbers are 10 or 11 digits long (including the leading 0, dropped when dialing from abroad) and follow a structure by number type.
Geographic numbers start with 01 or 02 followed by an area code tied to a city or region. (for example, +44 20 for London or +44 161 for Manchester). Non-geographic national numbers start with 03 or 033 and cost the same as a standard landline call. Mobile numbers start with 07, and toll-free numbers use the 0800 or 0808 prefix. Numbers starting with 0844, 0845, 0870, or 0871 are premium-rate and carry a per-minute charge.
When dialing from outside the UK, drop the leading 0 and dial +44 followed by the remaining digits.
For example, to call University College London, dial +44 20 7679 2000.

Frequently Asked Questions
Yes. Ofcom is the UK’s independent telecoms regulator and requires virtual and non-geographic numbers to be properly provisioned and correctly disclosed to callers. KrispCall’s UK numbers meet Ofcom’s numbering requirements.
UK virtual numbers come in three main types, each suited to a different business need. A local number uses an 01 or 02 prefix tied to a specific city or region, supports voice calls only, and signals a fixed business presence for companies building long-term UK customer relationships. It starts at $4/month. A mobile number uses a 07 prefix and supports both voice calls and two-way SMS, including OTP verification on platforms like WhatsApp, and isn’t restricted to domestic-only calling. It also starts at $4/month. A toll-free number uses the 0800 or 0808 prefix, supports voice calls, and is free for callers dialing from within the UK, ideal for customer support teams and helplines running high inbound call volumes. It starts at $5/month and requires a short document verification step to activate.
