UK International Calling Guide
Making an international call to the United Kingdom is straightforward once you understand the correct format. The UK country code is +44, and when dialing from abroad, you must remove the leading zero from the UK number.
⚠️ Important: Always drop the first “0” of the UK area or mobile code when calling internationally.
Basic Dialling Format
Use the following structure when calling the UK:
International Access Code + 44 + Area/Mobile Code (without 0) + Local Number
The international access code differs by country:
- USA & Canada: 011
- Most European countries: 00
- Australia: 0011
- Mobile phones: You can usually use the + symbol directly.
