The business advantages of a freephone number
Calls to 0333 numbers cost the same as calling a standard UK landline and are included in your callers' inclusive minutes on every major UK mobile network and fixed-line bundle. No premium surcharges, no surprises.
An 0333 number signals a modern, established UK business. It's the same number range used by major banks, retailers and service providers — customers recognise it as safe, professional and national.
An 0333 number gives your business a single national point of contact without tying you to a city or region. Route incoming calls to different locations based on time of day or team availability.
0333 numbers are accepted by the free WhatsApp Business app — unlike 0800 freephone numbers which require the paid Platform tier. Use one number for calls and WhatsApp without any per-conversation fees.
Unlike geographic 01/02 numbers tied to a physical address, your 0333 number travels with your business. Move offices, change providers, or expand without ever losing your number.
All UK 0333 numbers are regulated by Ofcom under the same rules as 0300/0345/0330. You have the legal right to port your number to any provider at any time. Your 0333 is a business asset you own and control.

Helpful guides from our telecoms team
The cost of an 0333 number depends on your provider and package. At Number Supermarket, virtual 0333 numbers come with your first 2 months completely free, then from £14.99/mo on our Solo package (500 inclusive minutes). Our most popular plan, The Works, is £24.99/mo with 1,000 minutes, call recording, and IVR.
There are no setup fees and no long-term contracts — you can cancel at any time. If you want to own your 0333 number outright, we also offer a one-off purchase option for £497, which includes full Ofcom portability rights.
For callers, 0333 numbers cost the same as calling a standard UK landline (01/02) and are included in every major mobile and landline inclusive-minute bundle — EE, Vodafone, O2, Three, BT, Sky, TalkTalk and Virgin Media. There are no premium surcharges; if a customer has any minutes left in their allowance, calling your 0333 is effectively free for them too.

The Works package is £24.99/month and includes 1,000 minutes, call recording, and IVR. You can also buy a number outright for a one-off payment of £497. There are no setup fees and no long-term contracts.
0333 numbers are not free to call in the same way that 0800 freephone numbers are, but they cost the same as a standard UK landline call (01/02) and are included in every major UK mobile and landline inclusive-minute bundle — EE, Vodafone, O2, Three, BT, Sky, TalkTalk and Virgin Media. For most customers, calling an 0333 effectively costs nothing because the call is covered by their plan's inclusive minutes. Ofcom requires all providers to treat 03 numbers (0300, 0330, 0333, 0345, 0370) identically to geographic 01/02 numbers for pricing.
0333 is not a geographic area code. It is a UK non-geographic number range introduced by Ofcom in 2007 (alongside 0300/0330/0345) to give businesses a national presence at standard landline call rates. 0333 numbers are not tied to any city or region, which is why they're popular with national businesses and SMBs serving customers across the whole UK.
Yes. When you buy an 0333 number from Number Supermarket, you can forward calls to any UK landline or mobile number. You can change your divert destination at any time through our online portal or smartphone app — useful for after-hours redirection, holiday cover, or routing different services to different teams.
Most 0333 numbers are activated within minutes of completing your order. You choose your number, select your package, and our system provisions it almost instantly. No engineers, no installations, no waiting.
Every 0333 number comes with 20+ features as standard, including call forwarding, voicemail to email, call recording, call whisper, time-of-day routing, hunt groups, IVR auto-attendant, and a web-based management portal.
No. An 0333 number works with your existing phone setup. Calls are forwarded to whatever number you choose — office landline, mobile, or home phone. There is no hardware to install and no software required.
Yes. Under Ofcom regulations, you have the right to port your 0333 number to any other provider. The porting process typically takes 1–2 working days. Your number belongs to you, not your provider — your 0333 is a business asset you control.
0333 numbers are used by businesses of all sizes across the UK that want a single national point of contact at standard landline call rates. They're especially popular with growing SMBs, customer service teams, property managers, professional services and any business that wants to project a modern, national presence without paying for an 0800 freephone or limiting themselves to a single geographic area code.
Yes — and this is one of the biggest advantages 0333 has over 0800 freephone. Unlike 0800 numbers (which the free app rejects), 0333 numbers are accepted by the free WhatsApp Business app you download from the App Store or Google Play. Verify by SMS or automated voice call, set up your business profile and start chatting with customers on the same trusted number you use for voice calls.
0333 numbers verify on WhatsApp Business in the standard way: you choose SMS or voice-call verification when you install the app, Meta sends a 6-digit code to your 0333, and you enter it. Most setups take about 30 seconds. (If you're using the WhatsApp Business Platform tier instead of the free app, verification goes through your BSP.)
For sole traders and small teams using one device, the free WhatsApp Business app is usually all you need — it handles auto-replies, away messages, quick-reply templates and a basic product catalogue at zero cost per message. Upgrade to the WhatsApp Business Platform (Cloud API) via a BSP like Sinch, Twilio, Vonage or Infobip when you need multiple agents, CRM integration, chatbots, or bulk customer notifications. Your 0333 number works with both tiers — you can switch later without changing your number.
No — WhatsApp messaging is free for customers on any UK mobile data plan or Wi-Fi. They pay nothing for messages, calls or media sent to your WhatsApp Business number. If you're on the free WhatsApp Business app, your side is free too. If you've upgraded to the Platform tier for multi-agent or chatbot use, you pay a small per-conversation fee to Meta via your BSP (typically £0.03–£0.06).
Yes — that's the whole point. One trusted business number handles both inbound phone calls (forwarded to your team) and WhatsApp Business chat (in the free app or Platform). Customers see consistent branding across your website, calls, signage and chat. WhatsApp registration does not affect call routing or anything else about how your 0333 works as a phone number.
0800 is a freephone number — completely free for callers, business pays per-minute. 0333 is a national-rate number — caller pays standard landline rate (almost always included in their allowance), business pays a lower per-minute rate. 0333 also works with the free WhatsApp Business app; 0800 does not. Choose 0800 if free-to-call is critical for your audience (helplines, vulnerable customers, charities). Choose 0333 for modern professional services that want national presence with lower business call costs and free-app WhatsApp compatibility.
