If you want handsets and apps alongside your number, our VoIP phone systems page explains how they work with your London lines.

Why London Businesses Choose a Local Number

London is where many UK and overseas companies want to be seen, and a 020 number places you in the capital at once.

Many firms use 020 London phone numbers to build a presence here without paying central London rents, from a start-up to an international group.

Finance and law cluster in the City and Canary Wharf, while technology and creative firms fill Shoreditch, King’s Cross and Southwark. A London number lets a business based elsewhere serve clients in all of those areas, and calls follow your people wherever they work.

Start-ups use 020 London phone numbers to look established before they have premises here, and firms in Manchester, Leeds or Kent add one so London clients can reach them on a familiar code.

Advertising with 020 London phone numbers is a simple way to reach customers across the capital and beyond, and you do not need a local office to do it.

Calls to your 020 number can be answered anywhere in the UK, which means a team in Manchester or a home worker in Kent can still present a London number. Customers in every district above will recognise the code.

0203, 0204, 0207 and 0208: Which London Number Should You Choose?

All four prefixes belong to the 020 London numbering area, and callers see the same 020 code whichever you pick. The ranges differ in which numbers are free and how they feel, not in the districts they serve.

0207

Long-established

0207 is one of the older ranges. Some firms choose it for that classic feel, although choice can be narrower because the range has been in use for decades.

0208

Also long-established

0208 is the other older range. It works for customers anywhere in the capital, and we check which numbers are free before you decide.

0203 and 0204

Widely available

0203 and 0204 were released as the older ranges ran short. Callers cannot tell an area from them, which makes them a good fit for any business wanting a London presence, and there is usually more choice.

If you are unsure, tell us what you want your number to say about your business and we will suggest a few options.
