Doing business in London
London is the UK's largest business centre and one of the world's leading financial capitals, with the City of London and Canary Wharf sitting alongside fast-growing technology, media and creative clusters in areas such as Shoreditch, King's Cross and Soho. Hundreds of thousands of businesses trade across Greater London, from global headquarters to one-person firms, so standing out matters. A recognisable 020 number still signals an established London presence to customers and partners, even when your team is remote or spread across several sites. With a cloud phone system you can hold a central London number and answer it from anywhere in the capital or the country.
How to get a 020 number for your business
With a Voxora cloud phone system you can get a brand new 020 (London) number in minutes, even if you are not based in London. Your calls ring on a desk phone, a mobile app or a web browser, so your team can answer a London number from anywhere. You can add call menus, voicemail to email, call recording and an AI receptionist on top, with no new phone lines or hardware.
Keep your existing 020 number
Already have a 020 number? You can move it to Voxora through number porting and keep it exactly as it is. Porting is normally free, your number does not change, and your calls simply start ringing on the new system once the transfer completes. This matters more than ever with the UK landline network switching off on 31 January 2027, when traditional phone lines are retired and every business needs an internet-based phone service.
Why a local London number still helps
A local 020 number signals to customers that you are an established, reachable business in the London area, which can lift answer rates and trust compared with an unknown mobile or non-geographic number. Because the number runs over the internet, you keep that local identity even if you move premises or work remotely.
How 020 numbers are written
London numbers are written as 020 XXXX XXXX, with 020 as the area code followed by the local number. Dial the full number including the leading zero from within the UK; callers from abroad replace the leading zero with +44.
