Introduction

If you have ever tried to make a purchase from an online store in Korea, you may have encountered the mobile authentication process. It can be frustrating when you repeatedly enter your phone number, but the system doesn't recognize it. This issue usually arises when you are using a temporary prepaid SIM card as a tourist and not as a long-term resident, which doesn't support mobile authentication.
You will soon realize how everything will be connected through mobile authentication, and almost every platform in Korea will use it for authentication and purchases.

The online shopping system in Korea is relatively closed, and many services require a Korean credit card and phone number linked to your Resident Card (ARC). To overcome this challenge, it's essential to understand the difference between a prepaid SIM card for tourists and a SIM card that is linked to your Resident Card.
 
If you are a foreign national staying in Korea for more than 90 days, you must apply for an Alien Registration Card (ARC). However, as of July 2020, the ARC has been replaced by the Resident Registration Card, which also serves as a national health insurance card.

Once you have completed the application process and received your Resident Registration Card, you will have access to a number of benefits as a Korean resident. These benefits include:
  1. The ability to open a bank account: You can now open a bank account without the need for a Korean national to act as your guarantor.
  1. National health insurance coverage: With your Resident Registration Card, you will have access to the National Health Insurance System, which provides affordable healthcare services to all residents of Korea.
  1. The ability to apply for a credit card: You can now apply for a credit card in your own name and without the need for a Korean national to act as your guarantor.
  1. Online shopping and authentication: With your Resident Registration Card, you can easily and securely shop online and use delivery services that require authentication. It also allows you to easily verify your identity when using various online services in Korea.
 

Steps to do in following order

 
  1. Connect your SIM card to Resident Card for online authentication
  1. Go to your nearest Bank and open up a Korean Bank Account
  1. KakaoTalk with Korean Phone Number
 

How to do Online Authentication

Have you ever tried to buy something from a Korean online store, only to be frustrated when the page wouldn't accept your phone number no matter how many times you entered it? This is likely because your phone isn't connected to your residence card, and you may have accidentally selected the wrong option. It's important to know that there's a difference between a prepaid SIM card and a SIM card provided directly by the carrier, which is typically more expensive with a longer contract duration. To avoid these issues, make sure to select the fourth option 알뜬폰.
