If you’re planning to move to the United Kingdom, one of the first things you’ll need is a UK number. Whether you’re relocating for work, study, or just travelling long-term, having a local number makes everyday life easier, from applying for jobs and renting accommodation to setting up bank accounts and receiving important texts.
Getting a UK number is also one of the first steps after securing your UK visa or Youth Mobility visa UK. Here’s everything you need to know, including formats, costs, and how to get one before or after you arrive.
This guide was last updated 07/03/2026 to reflect the latest UK phone number information.
🇬🇧 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.

🌍 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

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

💡 Tip: If you’re only visiting for a few months, a pay-as-you-go SIM is best.

Some options include:
- giffgaff – Ships free SIM cards internationally
- Lebara – Offers cheap international calling and eSIMs

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:

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.

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.

⚙️ Common Questions About UK Numbers
❓ Does +44 replace 0 or 07?

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.
