When you see a number starting with 020, you’re looking at a London line. The 020 country code question comes up often because the prefix looks like a country code, but it isn’t. It’s the area code for Greater London, and understanding it matters whether you’re calling the UK from Dubai, registering a business number, or routing calls through a cloud system. Let’s break down exactly what 020 means, how to dial it, and why it carries real commercial weight for businesses entering the UK market.
Quick Answer: 020 is not a country code. It is the geographic area code for Greater London, United Kingdom. The UK country code is +44. When calling a London number from abroad, dial +44 20 followed by the 8-digit local number, for example +44 20 7946 1234. All subscriber numbers within the 020 area consist of eight digits, covering the entirety of Greater London.
The 020 area code is London’s national dialling prefix, used since April 2000 when Ofcom unified the old 0171 and 0181 codes into a single Greater London identifier under the UK’s +44 country code.
What Is the 020 Area Code?
The 020 area code is the geographic dialling prefix for Greater London, United Kingdom. It is used for both residential and business landlines across all London boroughs, from Westminster and Camden to Croydon and Bromley. Internationally, it appears as +44 20.
You can activate a virtual London 020 number in under two minutes. No credit card required, no SIM card, no office address needed. Just sign up and your team is ready to call.

- Example format: 020 7946 0958

What Is the 020 Country Code and Where Is It Used?
If you’ve answered a call starting with 020, you were speaking to someone in London. The term “020 country code” is a common search phrase, but the accurate label is area code, not country code. The UK country code is +44, while 020 is the city-level prefix assigned specifically to Greater London by Ofcom, the UK’s communications regulator (Source: Ofcom Numbering Plan).
“We’ve seen teams based in Singapore and Dubai close UK deals faster once they switched to a 020 number. The answer rate difference is real. UK buyers are far more likely to pick up a local London number than an international mobile. In our experience working with 300+ sales teams, a local number is often the single cheapest conversion improvement available.”

In April 2000, London consolidated its phone networks under a single area code. The old 0171 prefix (inner London) and 0181 prefix (outer London) were retired, and 020 replaced both. So a number that used to be 0171 946 1234 became 020 7946 1234, and 0181 946 1234 became 020 8946 1234. The leading digit after 020 (7 for inner, 8 for outer) is now just part of the 8-digit subscriber number, not a separate sub-code.
If you’re calling a London number from abroad, you add the UK country prefix +44 and drop the leading zero from the area code. So 020 7946 1234 becomes +44 20 7946 1234. This format is what the London calling code looks like in international directories and is the starting point for setting up virtual calling plans through platforms like FreJun.
How Does the 020 Area Code Fit Within the UK Numbering System?
The UK’s National Telephone Numbering Plan, maintained by Ofcom, assigns area codes by geography so that millions of users stay connected without overlap. The 020 code sits at the top of the geographic hierarchy as the prefix for Greater London, the UK’s largest metropolitan area with over 9 million residents (Source: ONS Population Estimates 2023).
When the UK standardized its area codes, it also modernized local exchanges. All parts of London, from Westminster to Croydon, now operate under one uniform London dialling code. Here’s how 020 compares to other major UK area codes:
| City | Area Code | International Format | Subscriber Digits | Notes |
|---|---|---|---|---|
| London | 020 | +44 20 | 8 digits | Largest UK city; covers all 33 boroughs |
| Birmingham | 0121 | +44 121 | 7 digits | UK’s second largest city |
| Manchester | 0161 | +44 161 | 7 digits | North West England hub |
| Edinburgh | 0131 | +44 131 | 7 digits | Scottish capital |
| Leeds | 0113 | +44 113 | 7 digits | Yorkshire business centre |
London’s 020 code is unique because it carries 8-digit subscriber numbers rather than the 7-digit format used by most other UK cities. This gives London a larger pool of available numbers, which it needs given the density of businesses and residents in the capital.
Telecom providers, VoIP systems, and call centre solutions like FreJun rely on these codes to correctly route inbound and outbound traffic. That’s why businesses expanding into the UK often start by securing a +44 20 number. It signals professionalism and local presence from the first ring.
Why Is the London Dialling Code So Important for Businesses?
Having a London dialling code isn’t just about accessibility. It’s about reputation. The moment potential clients see an 020 number, they associate your company with credibility, reliability, and local authenticity. Research published in the Journal of Marketing Research shows that local phone numbers increase callback rates by 35-40% compared to international mobile numbers (Source: Sagepub, 2024).
How Does a 020 Number Benefit Your Business Specifically?
The biggest mistake most international teams make is assuming UK buyers will call back an overseas number. They won’t. A 020 number removes that friction entirely.
- Builds Trust: UK clients prefer calling local numbers, especially in a city as commercially influential as London.
- Improves Callback Rates: Ads with 020 numbers receive 35-40% more callbacks than those showing international mobile numbers (Source: Sagepub, 2024).
- Strengthens Brand Presence: A +44 20 number suggests stability, so small businesses appear established even when operating remotely.
- Cuts Call Costs: Using virtual phone providers like FreJun cuts international charges significantly compared to traditional landlines.
FreJun lets companies get multiple 020 numbers instantly, which is ideal for sales teams, customer support desks, or international offices managing UK clients. Your Dubai or Singapore-based office can appear local to London callers, while all calls route through FreJun’s cloud system in seconds.

How to Dial a London Number from Abroad Using +44 20?
Dialling a UK number from outside the country confuses a lot of people, but the pattern is consistent once you know it. The key rule is that the leading zero in any UK area code gets dropped when you add the +44 country prefix. So 020 becomes 20, and the full international number is +44 20 followed by the 8-digit subscriber number.
Step 1: Start with Your Country’s International Exit Code
Every country uses a different prefix to make international calls. It’s 00 in most of Europe, 011 in the US and Canada, and 0011 in Australia. This code tells your carrier that the call is leaving your country’s network. If you’re dialling from a mobile, you can skip this step and use the + symbol instead, since + automatically substitutes for any exit code.
Step 2: Enter 44, the UK’s Country Code
Once you’ve entered your exit code (or typed +), add 44. This is the unique identifier for the United Kingdom in the ITU-T E.164 international numbering plan (Source: ITU-T E.164). It ensures your call routes to the UK’s telecom network correctly.
Step 3: Drop the Leading Zero from the Area Code
When dialling internationally, the initial “0” used for domestic calls is no longer needed. You replace it with the +44 country code. So the domestic 020 becomes just 20 in the international format. This rule applies to every UK area code, not just London’s 020 country code prefix.
Step 4: Enter the 8-Digit Local Number
Type in the full 8-digit subscriber number after the area code. If you’re calling 020 7946 1234 from abroad, you dial +44 20 7946 1234. That’s the complete sequence. With VoIP systems like FreJun, you can assign London dialling code numbers to team members anywhere in the world, so they make calls that appear as local UK numbers without roaming charges or physical SIMs.

Frequently Asked Questions About the 020 Area Code
Is 020 a country code or an area code?
020 is an area code, not a country code. The UK country code is +44. The 020 prefix is the geographic dialling code for Greater London, assigned by Ofcom under the UK National Telephone Numbering Plan. When you call a London number from abroad, you dial +44 20 followed by the 8-digit subscriber number. The confusion arises because 020 looks like a short country code, but it functions at the city level, not the national level.
What area does the 020 code cover?
The 020 code covers the entirety of Greater London, including all 33 boroughs. This spans central areas like Westminster, Camden, and the City of London, as well as outer boroughs like Croydon, Bromley, and Barnet. Since April 2000, the old inner London code 0171 and outer London code 0181 were both replaced by the single 020 prefix, so the entire metropolitan area now shares one area code.
How do I call a London 020 number from the US?
From the US, dial 011 (the US international exit code), then 44 (the UK country code), then 20 (London’s area code without the leading zero), then the 8-digit local number. The full sequence looks like: 011 44 20 XXXX XXXX. If you’re calling from a mobile, you can replace 011 with + and dial +44 20 XXXX XXXX directly. Most smartphones handle the + format automatically when you hold down the 0 key.
Can I get a 020 London number without a physical office?
Yes. Virtual number providers like FreJun let you activate a 020 London number without a physical address, SIM card, or UK office. The number is cloud-based, so calls route to your team wherever they are. This is how businesses in the UAE, India, Singapore, and the US maintain a local London presence for sales and support without the overhead of a physical location. Setup takes under five minutes.
Why do some London numbers start with 0203, 0207, or 0208?
Numbers like 0207 or 0208 are not separate area codes. The full area code is 020, and the digit that follows (3, 7, or 8) is the first digit of the 8-digit subscriber number. So 0207 946 1234 is correctly written as 020 7946 1234. The 7 and 8 prefixes within subscriber numbers loosely correspond to inner and outer London respectively, but they carry no official geographic distinction under the current numbering plan.
How can I get a business phone number quickly?
You can sign up with FreJun and activate a 020 London number instantly, without any hardware or paperwork. The process takes under five minutes. You choose your number, connect it to your CRM, and your team can start making and receiving calls right away. FreJun supports Salesforce, HubSpot, Zoho, and a range of other platforms, so your call data flows directly into your existing workflow from day one.
Do I need a physical SIM card to use a 020 number?
No. FreJun’s 020 numbers are fully cloud-based, so your team can operate from anywhere without a SIM card or physical phone line. Calls run over the internet using VoIP (Voice over Internet Protocol) technology, which means you need only a stable internet connection and the FreJun app or browser interface. This works on desktop, iOS, and Android, so remote and distributed teams can use a London number from any device.
Can multiple team members share the same 020 number?
Yes. FreJun’s smart call routing lets you assign a single 020 number to multiple users or departments. Incoming calls can ring simultaneously across the team, route to the first available agent, or follow a custom sequence you define. This is useful for support teams that need a shared London number but want calls distributed intelligently rather than going to voicemail when one person is busy.
How long does FreJun setup usually take?
Setup takes under five minutes for most teams. You sign up, choose your 020 number, connect your CRM, and add your team members. There’s no hardware to install and no telecom contract to sign. FreJun’s onboarding is fully self-serve, though the support team is available if you need help configuring call routing, IVR menus, or CRM field mapping during the first session.
Is there a way to track call results automatically with a 020 number?
Yes. FreJun logs all call details automatically, including duration, outcome, recording, and transcript, directly to your CRM after every call. You can view call performance by rep, team, or number on the FreJun dashboard. This removes the need for manual call logging, which typically consumes 20-30 minutes per rep per day according to FreJun’s 2026 analysis of 300+ client accounts. The data is visible in real time, so managers can act on it the same day.
You now know exactly what the 020 country code question really asks and how to answer it. The next step is putting a live London number to work for your team. Most teams that book a demo are calling on a 020 number within the same week.
