Whether you’re calling for personal reasons or business communication, here’s how to stay connected with the United States without overpaying.
Understanding the USA–UK Calling Basics
Before making an international call, it’s important to understand the dialing structure. The USA and the UK use different country and exit codes, but once you know the format, calling becomes straightforward.
International Dialing Format
To call a US number from the UK, you’ll need:
- UK international access code: 00
- USA country code: 1
- Area code + local number
Example:
If the US number is (415) 555-1234, you would dial:
00 1 415 555 1234
This format applies whether you’re calling a mobile phone or a landline in the United States.
