How To Call the USA From the UK?

To call the US from the UK, you need to follow a specific sequence: the exit code, country code, area code, and local phone number. Here’s a step-by-step guide.

To call a US number from the UK, dial 00 from a landline or + from a mobile. 00 is the UK’s exit code for international calls. It signals that you’re dialing outside the UK.

Next, enter the US country code, which is “1”. This ensures your call routes to the United States.

After that, enter the 3-digit area code that identifies the specific region or city you want to reach in the US. Each area has its own unique code.

Finally, enter the 7-digit local phone number of the person or business you’re calling. Your call will then connect you to your intended recipient in the US.

Suppose you want to call Manhattan, New York, from the UK. If the area code for Manhattan is 212, and the local phone number is 537 9710, you would dial 00 1 212 537 910 (from a landline) or +1 212 537 910 (from a mobile).

US area codes are essential for making calls within the United States, including from the UK. They are the three-digit codes that identify the geographic region of phone numbers. Each area code represents a specific area, city, or part of a state, helping direct your call to the right place.

The table below illustrates some of the popular area codes in the US you may like to reach out to. For instance, if you are dialing 424 number (Los Angeles), it's essential to follow the correct dialing format to connect with your potential clients, family, or any other individual.
