Making international calls from Japan to the US can seem confusing if you’re not familiar with the right steps. Whether you’re connecting with family, friends, or business contacts, you must understand the proper dialing codes to call the US from Japan.

Calling the US from Japan | 4 Easy Steps

You need to follow a specific dialing sequence - the Japan exit code, the US country code, and the local phone number with the destination area code - to call the US from Japan.

Dial 010, Japan’s exit code, which allows you to place an international call.
Dial the US country code 1, which directs your call to the United States.
Enter the 3-digit area code for the specific city or region in the US.
Input the recipient’s 7-digit local phone number to complete the call.

💡 For Example:

If you want to call a number in New York City, USA, with the local phone number 555-1234, you dial 010 (Japan’s exit code), 1 (the US country code), 212 (New York’s area code) and then 555-1234.

So, the entire sequence to call the US from Japan would be 010-1-212-555-1234.

Understanding the US Area Code

Area codes in the United States represent specific geographical regions within the country, which makes it easier to identify where the call is directed. In the US, area codes are three digits long and precede the local phone number.
