How foreigners can authenticate themselves in Korea : This screen that pops up whenever you try to sign up for apps and homepages in Korea! For all 99% of the work done on the Internet in Korea, ‘self-authentication/real-name authentication’ is required. As a foreigner… Can I get my ID? Even if you are a foreigner, you can authenticate if you have a Korean phone number ✨ under your name.
Then, what is authenticate themselves in Korea
According to Article 2 Subparagraph 6 of the Electronic Signature Act, “certification” refers to the act of confirming and proving that the electronic signature generation information belongs only to the subscriber. In general financial business, ‘identification card’, ‘bankbook seal and password’ and signature’ are used, and online, public certificates, security card OTP, transfer password, SMS or ARS authentication, payment password, mobile phone phone authentication, and fingerprint authentication are used.
The reality is that there is confusion between “identification” and “certification” as the fintech industry is activated and “CNP (Card Not Present)” increases. “Identification” is a method of identifying whether a specific person is you through a specific method, and “certification” is a method of proving that a specific person is you through a specific method.
The difference is insufficient, so it is used in combination. In fact, even if it is used in such a mix, similar meanings are conveyed, so it is not distinguished by clear terms.
However, separating this, identifying whether it is you or not through real-name verification of the mobile phone in order to obtain a public certificate is defined as “identification.” Proving that you are a person using a public certificate that has already been issued for financial transactions is classified as “self-certification.”
It is a method of authenticating oneself by entering a mobile phone number in your name and checking whether it is the same as your name registered with the mobile carrier. Previously, it was introduced to minimize the use of resident registration numbers on the Internet due to the risk of personal information leakage while authenticating oneself using resident registration numbers.
Because Korea’s mobile phone identity authentication system is the only system in the world that requires personal information linked to carriers, unlike text message authentication of overseas services that can be used regardless of user nationality, country, or plan, overseas residents, foreigners, and prepaid phone users cannot use it. In all countries except Korea, private companies cannot check their identity through their previous numbers, and like Korean services, most services do not require identity authentication, and financial or adult services that require identity verification are checked through passports or international credit cards. So you should have a cell phone number in your name. If you have a mobile phone number, you can authenticate yourself because in Korea, you can authenticate yourself through mobile phone authentication.


What is cell phone authenticate themselves Korea?
It is a method of authenticating identity through mobile phone numbers or personal information registered in the computer of a telecommunication company. In addition, SMS authentication can be used even if it is a mobile terminal such as a tablet, not a communication device (folder phone, smartphone, etc.), if it has an SMS function and contracts with a carrier that can use SMS. In addition, mobile phone identity authentication is possible with prepaid phone (pre-paid SIM).In addition, even OPMD (data only) is possible if it is a contract that can receive text messages.

However, there are three things to be careful about.


- The opening of the USSIM shall be done with the alien registration card
Since I don’t have an alien registration card right after I come to Korea, I sometimes open it using my passport. If you open it with your passport, you can’t verify your identity.
If I have to open it with my passport
- Can I modify/add information later
- Keep your number and check in advance if you can apply for another USIM with your alien registration card
- Write the name in capital letters when opening the USIM
I need to capitalize my name on my alien registration card and passport to open the USIM

In fact, foreign friends who wrote their names in lowercase when they opened the USIM had a problem that they couldn’t authenticate no matter how much they used their names
- USIM must be opened face-to-face
USIM should be opened directly at the official certification agency. There are times when you apply non-face-to-face because you don’t have time, but in this case, unexpected problems are likely to occur. No matter how busy you are, go open for about two hours a day
It can be inconvenient and annoying to authenticate yourself/real name for everything. The fact that it is a necessary procedure to protect your personal information and prevent crimes! Let’s keep your personal information safe!
