How to Dial the US Internationally? Dialing Codes, Steps & Tips

When calling internationally, the US phone number format includes your country’s exit code, the US country code, the area code, and the subscriber’s number. Each plays a role in connecting your call accurately to the right person in America.

The exit code is the first number you need to dial when calling internationally. It signals to your phone network that you are trying to place a call to another country. The exit code is different depending on where you're calling from.

You can also replace the exit code with the “+” sign if you’re making a call using a mobile phone.

The country code for the USA is ‘1’. Dialing this code after an exit code directs every international call to the United States. 

The US area code represents a specific geographic region or city in the USA. This 3-digit number helps route the call to the area within the US.

Some popular area codes in the US with their respective regions:

The subscriber number in the USA is the 7-digit local number that identifies the person or business you are calling. This is the last part of the phone number and is unique for each user.

To dial a number in the USA from overseas, dial your country’s exit code first, then enter the US country code (1), area code, and the 7-digit local subscriber’s number.
