What Is the 020 Country Code and Where Is It Used?

Chances are, if you’ve ever answered a call that starts with 020, you’re speaking to a Londoner one of the most populous in the world. The 020 country code is technically not a dialing code, but a city dialing code. It’s the code assigned to London and the surrounding area. In 2000, London consolidated its phone networks and the new system required a single area or city code 020 replaced the old 0171 and 0181 area codes.

If you’re calling a London number from abroad, you’ll have to tack on the UK’s country prefix (+44) to get to the format most people are familiar with, +44 20. So if the London number you’re calling is 020 7946 1234, the international number would be +44 20 7946 1234. This ensures that the London calling code is recognizable worldwide and a great starting point for mapping out virtual calling plans with us here at FreJun.

How to Dial a London Number from Abroad Using +44 20?

For many international callers, dialing a UK number can be confusing. But it’s quite simple once you understand the pattern.

Here’s how it works step-by-step:

1. Start with Your Country’s International Exit Code

Every country uses a different prefix to make international calls. For example, it’s 00 in most of Europe, 011 in the U.S. and Canada, and 0011 in Australia. This code tells your carrier that the call is leaving your country’s network.

2. Enter 44 — The UK’s International Code

Once you’ve entered your exit code, the next step is adding 44, the unique identifier for the United Kingdom. This ensures your call is routed to the UK’s telecom system, connecting you to the correct national network.

3. Skip the First “0” from the Area Code

When dialing internationally, the initial “0” used for domestic calls is no longer needed. Replacing it with +44 automatically directs the call to the right region, such as London under the 020 country code.

4. Enter the Local Number

Finally, type in the rest of the phone number after the area code. For example, if you’re calling 020 7946 1234 from abroad, you’d dial +44 20 7946 1234. And that’s it you’re instantly connected to the London dialing code network.

Example:The entire process is seamless when using VoIP systems. With FreJun, you can even assign London dialing code numbers to team members abroad, letting them make calls that appear as if they’re from the UK all without roaming charges or physical SIMs.
