Quick Overview: Getting a UK Number
The easiest way to get a UK number is usually to buy a pay-as-you-go SIM or eSIM after arriving in the UK.
You may also be able to:
- order a SIM before you arrive
- set up an eSIM online
- use a virtual number for specific needs such as business or app-based calling
For most new arrivals, a normal UK mobile number is the best option for jobs, housing, and everyday life.
🇬🇧 What Is a UK Number?
A UK number is a local phone number that starts with the country code +44. It allows you to make and receive calls while in Britain and is required for most registrations such as banking, healthcare, or job applications.
Example:
📱 +44 7123 456789
Breakdown:
- +44 – the international UK country code
- 7 – mobile numbers always start with 07 inside the UK
- 123 456789 – the unique subscriber number
If you’re calling from inside the UK, you would simply dial 07123 456789.
If calling from abroad, you replace the 0 with +44, so it becomes +44 7123 456789.
🔢 UK Number Format Explained
| Type of number | Example | Notes |
|---|---|---|
| Mobile | +44 7xxx xxxxxx | Always begins with 07 |
| Landline | +44 20 xxxx xxxx | Area codes like 20 (London), 121 (Birmingham), etc. |
| Freephone | +44 800 xxx xxxx | Free to call within the UK |
| Business or VoIP | +44 330 xxx xxxx | Often used for companies or online accounts |
🌍 Why You Need a UK Number
If you’re relocating to the UK, even temporarily, a UK number is essential. You’ll need it for:
- Contact details on your visa sponsorship application
- Receiving texts from banks, landlords, or employers
- Verifying your identity for online services
- Signing up for UK healthcare and public services
- Staying connected via WhatsApp, Uber, or UK job portals
💡 If you’re arriving under the Youth Mobility Scheme or Graduate visa, getting a UK SIM early helps you find housing and work much faster.
📱 How to Get a UK Number
1. Buy a UK SIM card (easiest option)
You can buy prepaid SIM cards at the airport, phone shops, or supermarkets such as Tesco Mobile, EE, O2, or Vodafone.
- No contract required
- Usually costs £10–£20 for setup
- Includes data, calls, and texts
💡 Tip: If you’re only visiting for a few months, a pay-as-you-go SIM is best.
2. Order a UK number online before you arrive
If you’re applying from abroad, several providers let you set up a UK number remotely, which can be activated once you land.
Some options include:
- giffgaff – Ships free SIM cards internationally
- Lebara – Offers cheap international calling and eSIMs
- UK Virtual Number providers – For those who want a number for forms or WhatsApp verification
This is particularly useful if you’re preparing documents for your UK visa application and want to list a local contact number.
3. Get a virtual UK number for WhatsApp or business
irtual or VoIP UK numbers work through the internet. You can make and receive calls using an app, without needing a physical SIM.
These are popular for:
- Remote workers
- Digital nomads
- People who need a UK WhatsApp or business line
Free UK numbers do exist, but most have limited minutes or expire after a period of inactivity. Paid versions cost around £2–£10 per month.
💬 Using a UK Number on WhatsApp
You can link your UK number to WhatsApp once your SIM is active.
Even if you move abroad again later, you can keep using your UK WhatsApp number as long as you have the SIM or account active.

🔐 How to Check a UK Number

A valid UK number always starts with +44 (international) or 0 (domestic).
Getting a UK Number After Arriving
For many new arrivals, getting a UK number is one of the first practical tasks after landing.
It often helps with:
- speaking to landlords or agents
- applying for jobs
- setting up a bank account
- using delivery, transport, and messaging apps
- receiving important security or verification texts
That’s why many people sort this out in their first few days in the UK.
⚙️ Common Questions About UK Numbers
❓ Does +44 replace 0 or 07?
When dialling internationally, +44 replaces the first 0. For example:
07123 456789 → +44 7123 456789.
❓ Is the UK phone code +44 or 0044?
Both work — “0044” is just another way to write “+44” when calling from some countries that use 00 as the international prefix.
❓ Why do UK numbers start with 07?
All UK mobile numbers start with 07 to distinguish them from landlines (which start with 01 or 02).
❓ What is the full UK number format?
For mobiles: +44 7xxx xxxxxx
For landlines: +44 20 xxxx xxxx (London)
❓ Can I get a free UK number?
Yes, some providers like giffgaff and Three offer free SIM cards (you just top up credit later). Virtual numbers sometimes have free trial periods too.
Getting a UK number is quick and affordable and it’s essential for anyone living, working, or studying in Britain. Whether you want a SIM for everyday use, a UK number for WhatsApp, or a virtual UK number to receive calls internationally, there’s an option that fits your lifestyle.
💡 Tip: Activate your UK SIM as soon as you arrive, so you can receive important texts from banks, landlords, or employers without delay.
