Here’s a guide to calling the United States from South Korea (with dialing format) and the perfect time to do so. We discuss a US virtual phone number to place an international call and the benefits of doing so. Toward the end, we also reveal a list of the top 5 virtual phone system providers to rely on. Let’s get started!

How to Call the US from Korea? 

Here is the step-by-step process to place an international call to the United States from South Korea mobile or landline –

Step 1: Key in South Korea exit code

To make an international call to United States from South Korea, dialing the South Korea exit code is mandatory. The South Korea exit code slightly differs from carrier to carrier when dialing via landline. It can be 001, 002, 008, 00345, 00700, 00388. 

However, if you’re trying to reach the United States from South Korea cell phones, replace the South Korea exit code with a plus (+) sign. 

Pro-tip

"International calling at low costs becomes easy if you can efficiently balance all the required elements. The major one is the medium you rely on–a traditional line or modern virtual phone system. Today, choosing a virtual number is better for its cost-effectiveness, high reliability, and advanced features. Doing so lets you get rid of the expensive, unpredictable charges too!"

Step 2: Dial the US country code 

After the South Korea exit code, dial the US country code. Country code is a unique code assigned to every country that allows you to reach a contact residing there. So, to reach the United States from South Korea, enter the US country code (1).

Step 3: Enter the US area code

Once you’re done typing the exit and country codes, quickly enter your contact’s US area codes to route your call correctly. The US has a total of 291 area codes; dial the one that’s relevant to your contact. Search for the US area codes here!

Step 4: Type the local phone number

After the mandatory codes–exit code, country code, and area code, complete the dialing process by entering the US recipient’s local phone number. 

For instance, you want to reach your US contact in Seattle, whose US phone number is 1234 567. You must follow this US phone number format: 001-1-206-1234 567 (when calling United States from South Korea landline) and +1-206-1234 567 (when calling United States from South Korea mobile) while international calling United States. 

When to Call the US from South Korea? 

Now that you know how to call the United States from South Korea correctly, remember to do it at the right time (consider the US current time) to successfully meet the purpose of your call–fruitful business discussions. 

As South Korea runs around 15 hours ahead of the US, the perfect time to call the United States from South Korea is around 7 AM to 11 PM in Korea which’d be around 4 PM to 8 AM in the US. 

Invest in a Virtual Phone System to Make International Calls to the US from Korea

Now that you know how to call the United States from South Korea, you must be excited to reach out to your American clients and customers. But here’s the catch, making international calls from South Korea to the US involves high calling charges and rolls out big bills. 

Also, when you call your South Korea number to your US customer, they may not pick it up as it will be a random unknown international number. And not being able to reach your customers can negatively impact your sales. 

Take a breather as we have a solution to your problems–a virtual phone system. A virtual phone system will provide you with a local US phone number regardless of your location that your customers will happily pick up without a shred of doubt about your South Korea business. 

You can use US virtual numbers from South Korea effortlessly and build a strong local presence there. On top of it, your customers will willingly contact you as they’ll not be charged at international rates. 

Reasons to Use a Virtual Phone System for Your Business 

94% of businesses have experienced improved security after switching to the cloud (VoIP). That’s a major reason you must consider using a virtual phone system. But wait, there are more reasons why you cannot miss out on virtual phone systems –

1. Significantly reduce calling costs

If you’ve newly expanded your South Korea business to the US, you’d have a long list of US contacts to call. Are you worried that connecting with numerous contacts would add up to thousands of dollars in bills? 

Not anymore; with an efficient virtual phone system like DialerHQ, you can call at local rates via virtual local phone numbers. You can get a local US virtual phone number and start making international calls at affordable prices.

2. Increase your advertising ROI

When you mention your US virtual number with a local area code number across your ads in the US, your American contacts will trust you more and are more likely to reach out. This US virtual phone number can also help you get featured in US business listings and local directories.

3. Adopt remote working

A virtual phone system lets you operate your business at any location from anywhere in the world. For example, if you get DialerHQ’s US virtual phone number, you’ll get access to their app, enabling you to make and receive client and customer calls from anywhere without missing any calls. 

4. Improve scalability

As a growing business, you’ll inevitably experience a rise in inbound and outbound calls, requiring you to hire new agents. In such a scenario, traditional lines would demand additional hardware and complex systems. In contrast, with virtual systems, you can scale and expand your support team with plan upgradation or new user addition at minimal costs. 

5. Access to edgy features

With a robust virtual phone system, you get access to advanced calling features such as IVR, call routing, call recording, CRM integration, and more that help you increase efficiency and performance.

For instance, call center analytics can help you customize your offers and marketing strategies by providing deep insights into your potential customers’ preferences.
