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.

Moving your number costs nothing and takes five working days at most
You keep the number that is on your shopfront, your invoices and in Google. We arrange the switch with your current provider and schedule it on a date that suits you, so you are never unreachable.
Why a 020 number means something here
London generates roughly a quarter of UK GDP and hosts more than 1 million registered businesses, from sole traders in Hackney to the European headquarters that cluster along Canary Wharf, the Square Mile and the King’s Cross tech corridor. A 020 number is the single clearest signal to UK customers that your company operates in the capital rather than further afield.
Whether you run an e-commerce brand from Shoreditch, a professional-services firm in Mayfair or a logistics operation near Heathrow, a 020 number ties your branding to London without you having to lease a central office.
Google treats your phone number as a location signal. A 020 number on your website, your Google Business Profile and in business directories tells Google that your business belongs to London, as long as you write it the same way everywhere, with the same spacing and separators.
Which places fall under 020, including the edge cases, is set out in our article on the 020 area code.
Frequently asked questions about London 020 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 020 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 Brighton, St Albans or Reading can answer calls on the same 020 line through the CallFactory app or any SIP handset, so customers still see a single London point of contact.
Yes. Porting a working 020 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.
Plenty of London businesses do exactly that. The 020 attracts customers in the capital, 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 020 area spans the whole of Greater London, which means all 32 London boroughs together with the City of London. That includes the business districts of the City, Canary Wharf, Westminster and Shoreditch, as well as outer boroughs like Croydon, Bromley, Ealing, Hounslow and Barnet. Heathrow Airport and the adjacent commercial estates also fall inside the 020 area. The full list, with the edge cases, is in our article on the 020 area code.
Historically, 020 7 served Inner London and 020 8 served Outer London, so that Ofcom could split the capital across two numbering ranges. Since the 2000 renumbering all four prefixes are equal — every 020 number covers the whole of Greater London regardless of the first digit after the area code. 020 3 was opened in 2005 and 020 4 in 2019 once the older ranges filled up. Pick whichever combination reads best for your brand.
Yes. Every Greater London postcode falls inside the 020 area, so a business registered in Hammersmith, Stratford, Croydon, Wimbledon or any of the other outer boroughs gets a full 020 number rather than a different regional code. That matters for companies sitting on the M25 edge, because customers read 020 as “London” no matter which borough the office is in.
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.
The 020 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.
