To get an 020 London phone number, choose a provider that offers London geographic inventory, confirm the documentation requirements, select an available number, and configure where its calls should ring. A cloud business phone service can let an eligible company use the number through web and mobile apps instead of installing a traditional London landline.
The correct London area code is 020. Numbers are normally written as 020 xxxx xxxx. The first digit of the eight-digit local number may be 3, 4, 7, or 8, but “0207” and “0208” are not separate London area codes.
What is an 020 number?
An 020 number is a UK geographic telephone number associated with London. It gives callers a recognisable London contact point and follows the National Telephone Numbering Plan administered by Ofcom, the UK communications regulator.
A London number has eleven digits when the leading zero is included: 020 followed by an eight-digit subscriber number. From outside the United Kingdom, the leading zero is dropped and the country code is added, for example +44 20 xxxx xxxx.

Are 0203, 0204, 0207, and 0208 different area codes?
No. The area code is 020 in every case. The 3, 4, 7, or 8 belongs to the local eight-digit number. The distinction matters when a company formats the number on a website, imports it into a CRM, or gives it to an international caller.
Older habits explain why people often say “0207” or “0208,” but businesses should display the official 020 grouping. It is clearer for customers and less likely to create validation errors in forms and databases.
How to get an 020 London number
- Decide what the number must do. List the users, expected call volume, business hours, forwarding destinations, voicemail, SMS requirements, and whether the number must be shared by a team.
- Search current London inventory. Use the LimePhone number checker and select the United Kingdom, a local number, and London where available.
- Review the eligibility requirements. Carrier and regulatory checks can require identity, business, address, or intended-use documents. Requirements can change and differ by number type.
- Choose an available number. A particular 020 range or digit pattern is not guaranteed. Inventory changes as numbers are allocated, reserved, or returned.
- Choose the business phone plan. Confirm which users, numbers, calling, recording, texting, routing, and support features are included. Review LimePhone pricing and calling and SMS rates.
- Set the call flow. Add users, business hours, ring order, voicemail, and fallback handling before advertising the number.
- Test the complete journey. Call from a UK mobile and another network, confirm caller ID, test voicemail and transfers, and verify that messages work only if the exact number is SMS-capable.
What documents might be required?
The exact checks depend on the provider, carrier, applicant, and intended use. A business may be asked for:
- a government-issued identity document for the authorised person;
- company registration details;
- proof of a business or residential address;
- an explanation of how the number will be used;
- contact information for the responsible account owner.
Do not upload false or unrelated documents to obtain a local number. If the application is incomplete, activation may remain pending or the carrier may reject it. The fact that a number appears in search inventory does not mean every applicant is eligible.
Can I get an 020 number outside London?
A virtual phone service can make it technically possible to answer a London number from another location, but eligibility and use must still follow the provider's rules and UK numbering requirements. A business should not use a geographic number to mislead callers about where it operates.
Use the website, contact page, and call greeting to describe the business accurately. A London number can be a convenient contact point for customers; it is not proof that a company has a staffed London office.

The right choice depends on reliability requirements, existing equipment, compliance, emergency calling, internet resilience, and how the team works. A distributed small business often values the flexibility of a virtual phone number. A site with specialist continuity requirements may need a more detailed network design.
How much does an 020 number cost?
The customer cost can include the subscription, additional users or numbers, outbound calls, SMS, taxes, carrier charges, and optional features. Do not compare providers using the headline number fee alone.
Before buying, ask:
- Is a UK number included in the selected plan?
- What does each additional number cost?
- Are inbound calls included or metered?
- What are the UK and international outbound rates?
- Does the number support business SMS, and are registration charges involved?
- Are taxes, emergency-service fees, or carrier charges added at checkout?
- Does the plan impose fair-use or destination restrictions?
LimePhone currently treats eligible UK numbers as included in supported plans, but inventory, capability, documentation, fair-use, and add-on rules still apply. Confirm the live checkout details for the selected number.
Can an 020 number receive SMS?
Do not assume it can. Geographic voice availability and SMS capability are separate. Messaging support depends on the specific number, carrier, registration, and product configuration. If texting is essential, verify the exact number before publishing it on adverts, invoices, or customer-service pages.
Businesses using SMS must also manage consent, sender identification, opt-out requests, message content, and applicable UK data-protection and marketing rules. See LimePhone's business texting workflow and obtain appropriate compliance advice for the campaign.
Can I transfer an existing 020 number?
Many London numbers can be ported, but the losing and gaining providers must confirm eligibility. Keep the old service active until the transfer completes. Prepare the exact account name, installation or service address, number list, account reference, and authorised contact details.
Do not change or cancel the old account during an active port unless instructed. A mismatch can delay or reject the request. Start with LimePhone's port your number guide.
How should a business configure its London number?
Set business hours and fallback handling
Decide what happens during open hours, when everybody is busy, and after closing. A good flow might ring a primary team, fall back to another group, and then offer voicemail or an approved answering workflow. The caller should never be trapped in a loop.
Keep the greeting accurate
State the business name clearly. If calls are recorded, transferred internationally, or handled by automation, provide the notices required for the use case. Avoid implying a staffed London office if the team operates elsewhere.
Assign ownership
For shared numbers, define who owns missed calls, voicemail, messages, and follow-up. A number alone does not prevent missed opportunities; the team needs visible responsibility and a response process.
Monitor quality
Test routing after staff, schedules, or devices change. Track missed calls, answer times, transfer failures, and customer feedback. Remove access promptly when a user leaves the company.
Common 020 number mistakes
- Writing 0207 or 0208 as the area code. Use 020 xxxx xxxx.
- Buying before checking documentation. A number can remain unavailable until verification is approved.
- Assuming SMS is included. Confirm capability for the exact number.
- Cancelling before a port. Keep the existing service active.
- Ignoring international formatting. Publish +44 20 xxxx xxxx for overseas callers.
- Using a London number to create a false impression. Describe the real operating location and service area accurately.
- Skipping call-flow testing. Test open, busy, unanswered, and after-hours scenarios.
Frequently asked questions
Is 0207 a London area code?
No. London uses the 020 area code. The following 7 is part of the local eight-digit number.
Is an 020 number a mobile number?
No. It is a London geographic number. It can be delivered through a cloud phone service, but that does not turn it into a UK mobile-range number.
Do callers pay extra to call an 020 number?
020 calls are generally charged like other UK geographic calls and may be covered by the caller's inclusive allowance. The caller should check their own provider and plan.
Can several employees answer the same 020 number?
Yes, if the business phone platform supports shared numbers, multiple users, routing, and permissions.
Can I use the number on a mobile phone?
Yes, through a supported business phone app or configured service. The public business number remains separate from the employee's personal mobile number.
Can I get a particular 020 number?
You can choose from available inventory, but a precise number or range cannot be guaranteed.
