How To Call US From Korea?

 

If you are exploring how to dial US from Korea, follow the below steps. 

Step 1: Dial the South Korea exit code

The first step in calling the United States from Korea is to enter the exit code for Korea. The South Korea exit code is 001 and 002, and you must dial this before you make any international call from Korea. Based on your carrier type, you should dial one of the following codes- 008, 00700, 00388, 00345.

Step 2: Dial the country code of the USA

While the exit code routes the call out of the country, the ISD codes help navigate the call to a country. For the USA, the country code is 1. So, after entering the exit code, you must enter 1. 

Step 3: Enter the area code

When you enter Korea’s exit code and the USA’s ISD code, the call gets routed from South Korea to the USA. The next step is to enter the city’s area code or region of the person you are trying to reach. There are around 335 area codes in the USA. So, when you dial a person in the USA, make sure that you enter the correct area code.

Step 4: Enter the US phone number

After you have entered the area code, the last step is to dial the US phone number. They come in 7 digits, so the dialing format to call the US from Korea is 001 – 1 – area code – local phone number. If you are dialing your business connection in New Jersey that has an area code of 201, then your dialing format is  001 – 1- 201- XXX XXXX (Exit code- ISD code – Area code – Local phone number)
