What is the 0203 area code for?

A few decades ago, London's old area code, 01, was running out of possible number combinations, so the decision was taken to change it. After a couple of further alterations that followed, Londoners now have four different landline area codes they can obtain, 0207, 0204, 0208, and 0203. Businesses that are based in the capital and a few surrounding areas will often have 0203 numbers. Consumers and commercial operators alike will tend to recognise an 0203 phone number as one that is associated with London and assume calls to it will be answered by a London-based business.

However, with a virtual 0203 number, businesses of all sizes can get the benefits of a London-based phone number without needing to maintain an office in the city. Calls to them can end up anywhere you like, such as a mobile phone or an office in a town (or country!) many miles away from the UK's capital. This means that anyone who wants one can publish an 0203 phone number no matter whether they operate in London or not.

How can businesses obtain an 0203 phone number outside of the capital?

If you think that one or more 0203 numbers might be beneficial for your business, then all you need to do is to apply for one with Cleartone Communications. Just fill in the form and we will do the rest, supplying you with an 0203 number you can start trialling for FREE for 30 days with immediate effect. We offer three call packages, all of which include disaster recovery so your calls will always be answered even if your other phone lines go down for whatever reason.

All of our 0203 number clients can decide where calls to their 0203 phone number are answered by logging into their secure online dashboard. You can even alter where calls are forwarded to depending on the time of day. Other features you can choose to take advantage of include missed call alerts, call whisper announcements and Business WhatsApp integration, among others.

What are the commercial advantages of 0203 numbers?

When you buy 0203 numbers for your business, callers will simply be more keen to call it than other numbers. Certainly publishing a contact number with an 0203 area code is more professional, for example, than having your mobile number on your business card or website. Secondly, the 0203 area code has a certain level of recognition over other geographical numbers.

In other words, when you buy virtual 0203 numbers, people will be more likely to assume you are running an established and stable business because you have a London-based office even if calls to it are forwarded to another part of the country or even your mobile phone. For some, this means being able to grow their business not just in the UK but in overseas territories, too, as more people will call an 0203 number more than many other types.
