How to Send a WhatsApp Message to UK

UK mobile numbers use the country code +44. Locally a UK mobile is written with a leading zero, like 07700 900123. For international format, drop the leading zero and prefix the country code: 447700900123.

Enter just the 10 digits after the leading zero in the form above (so 7700900123 for the example). The +44 is already filled in. Click Connect to WhatsApp and the chat opens.

WhatsApp is the dominant messaging app in the UK — used by the majority of mobile users. Click-to-chat is very likely to succeed for any active UK mobile number.

About UK Mobile Numbers

UK mobile numbers locally are 11 digits starting with 07 — for example 07700 900123. The leading zero is a "trunk prefix" used only when dialling within the UK; it must be dropped for international format.

After dropping the zero you have 10 digits, all starting with 7. The full international number is +44 followed by those 10 digits, totalling 12 digits including the country code.

Numbers starting with other digits (like 01, 02, 03) are UK landlines and are unlikely to have WhatsApp accounts. The click-to-chat tool only works reliably with mobile numbers.

  • Works with EE, O2, Vodafone, Three, and MVNOs. Network-independent — any UK mobile number registered with WhatsApp works, including operators like Giffgaff, Tesco Mobile, and Lebara.
  • Ideal for UK property and service enquiries. Estate agents, tradespeople, and service providers receive WhatsApp enquiries constantly. This tool lets you reply without cluttering your contacts.
  • Helpful for messaging across the EU. UK is a key business and tourist hub for Europe. Travellers and remote workers can message UK contacts without permanently saving them.
  • No personal data stored. Under UK GDPR, mobile numbers are personal data. This tool processes them only in your browser — they are never transmitted to or stored on any server.

Frequently Asked Questions: UK

What is the country code for the UK?

The international country dialing code for the United Kingdom is +44. The same code covers England, Scotland, Wales, and Northern Ireland. When using Instant Message Connector, enter 44 (without the plus sign) followed by the local mobile number with the leading zero dropped.

Should I drop the 0 from a UK number?

Yes. The leading 0 in a UK mobile number (like 07700 900123) is only used for dialling within the UK. For international format, drop the 0 and prefix +44. So 07700 900123 becomes 447700900123.

How many digits is a UK mobile number after dropping the 0?

Ten digits. All UK mobile numbers, once the leading 0 is dropped, are 10 digits long, starting with the digit 7.

Does this work for UK landlines?

Generally no. UK landlines use area codes like 01, 02, or 03 and rarely have WhatsApp accounts registered to them. The tool works reliably only for UK mobile numbers (those starting with 07 locally, or 447 internationally).

Will it work for Northern Ireland?

Yes. Northern Ireland shares the +44 country code with the rest of the UK. NI mobile numbers also start with 07 locally — drop the zero, prefix +44, and the click-to-chat link works identically.

Can I message a UK WhatsApp Business number this way?

Yes. WhatsApp Business and personal WhatsApp share the same click-to-chat link format. As long as the number has a registered WhatsApp account (either type), the chat will open.
