Open Banking in Korea for Foreigners: How to Link Your Bank Accounts
 |
| A foreign resident in Korea uses a smartphone to manage bank accounts through an Open Banking service. |
Your salary arrives in your Hana Bank account.
Your rent comes out of Shinhan Bank.
And your everyday spending goes through another account.
Three accounts. Three banking apps. Three passwords to remember.
Then you notice your Korean coworker checking several bank balances on one screen.
“Why don't you just use Open Banking?”
That sounds wonderful.
You open your banking app, choose Add Another Bank Account, and start the registration process.
Then an error appears.
Identity verification failed.
You have a Korean Residence Card, a bank account, and a mobile phone. So why can't you connect your accounts?
The short answer: Foreign nationality alone does not establish that every Open Banking service is unavailable. But whether you can register depends on the participating institution, your account, and the identity-verification methods supported by the app.
Here's how to find the problem without visiting three bank branches unnecessarily.
What Is Open Banking in Korea?
Open Banking (오픈뱅킹) allows participating financial institutions and authorized service providers to offer services connecting accounts across different banks.
The Korea Financial Telecommunications & Clearings Institute (KFTC, 금융결제원) operates the shared infrastructure.
Its official system supports functions such as:
Checking account balances
Viewing transaction histories
Registering supported accounts
Initiating supported transfers between accounts
This means you may be able to manage accounts from several banks through one participating app.
However, the functions available to you depend on the provider and the accounts connected.

Can Foreigners Use Korean Open Banking?
Foreign customers should not assume that every Open Banking service is automatically closed to them.
Equally, holding a Residence Card does not guarantee access to every bank or fintech app.
The practical question is whether your specific app accepts your identity-verification method and supports the account you want to register.
A bank may accept your identification for ordinary account transactions while a separate mobile service uses a different registration process.
There is also an important distinction in official guidance.
In November 2025, Korea introduced an Open Banking Blocking Service (오픈뱅킹 안심차단서비스) to help prevent unauthorized account access.
The Financial Services Commission states that this particular protection service is available to eligible Korean nationals and excludes foreign nationals.
That is a restriction on the blocking service, not proof that every ordinary Open Banking function is unavailable to foreigners.

Why Does Account Linking Fail?
1. Your Identification Information Needs Checking
Foreign customers may have identification records created at different times.
Perhaps you opened your first bank account using a passport, then received a Residence Card months later.
Your bank may need updated identification information for certain services.
If registration fails, ask the bank whether the identification record attached to your account is current.
Don't assume that every passport-opened account is permanently excluded from Open Banking.
2. Your English Name May Be Recorded Differently
Suppose your name is:
SMITH JOHN MICHAEL
One bank may display the full name, while another uses a shortened middle name or different spacing.
That difference may be worth checking if your error specifically concerns identity information.
But it would be misleading to claim that every Open Banking failure comes from an exact character-by-character comparison of English names.
Ask which identification field failed before requesting changes to your bank records.
The correct solution is to make sure each institution holds accurate identification information—not to guess which spelling an automated system prefers.
3. Your Mobile Authentication Fails
Some banking and fintech apps require Korean mobile identity verification.
A tourist SIM or a phone subscription not registered under the required identity information may not support that process.
If the error occurs during mobile verification, check with the app and your mobile provider.
If it occurs later, during account registration, the cause may be different.
4. The App or Account Has Its Own Restrictions
Not every account type or customer category is supported by every service.
An app may also have specific registration rules for international customers.
Before assuming that the KFTC network rejected your nationality, ask the provider whether the account and customer registration method are supported.
How to Fix the Problem: Five Practical Steps
Step 1: Identify Where Registration Failed
Write down the exact error message.
Was it displayed during:
Mobile identity verification?
Account ownership confirmation?
Account registration?
Transfer authorization?
Also record the app name and the bank holding the account.
A screenshot can help customer support, but never share passwords or verification codes.
Step 2: Check Your Bank Account Information
Contact the bank holding the account you want to link.
Ask whether the account is eligible for Open Banking and whether its identification record is current.
If you originally opened it using a passport, mention that you now have a Residence Card.
If an English-name discrepancy is suspected, ask the bank to verify the registered details against your accepted identification.
Step 3: Confirm the Authentication Method
Your app may request mobile verification, account ownership confirmation, or a supported certificate.
금융인증서 (Financial Certificate) and 공동인증서 (Joint Certificate) are used in Korean financial services, but neither is a universal requirement for every Open Banking registration.
Follow the authentication method supported by your particular app.
Step 4: Try Your Bank's Own Mobile App
If a third-party app cannot register your account, check whether your main bank offers an Open Banking connection feature.
This may help determine whether the difficulty is specific to the app or relates to the account itself.
It is a troubleshooting step, not a guaranteed workaround.
Step 5: Ask the Right Customer Service Team
If verification fails before an account is selected, contact the app provider.
If the error relates to an account's identity record or eligibility, contact the bank holding that account.
Ask for the specific reason the registration was rejected.
That answer matters more than repeatedly trying different buttons.
Does Open Banking Mean Free Transfers?
Not necessarily.
Many Korean banks and fintech services offer free transfers, but their customer fee policies can differ.
The existence of the shared Open Banking infrastructure does not mean every provider must offer every transfer free of charge.
Check the fee displayed by your app before confirming a transaction.

Before Visiting a Bank: What to Prepare
Bring your accepted identification, such as your Residence Card, and have the following information ready:
The name of the app where registration failed
The bank and account you tried to connect
The exact error message
Any relevant information about an earlier passport-based account opening
You can say:
“오픈뱅킹으로 다른 은행 계좌를 연결하려는데 본인확인 오류가 납니다. 제 계좌의 실명확인 정보와 오픈뱅킹 등록 가능 여부를 확인해 주세요.”
“I'm trying to link another bank account through Open Banking, but identity verification is failing. Could you check my identification records and whether this account can be registered?”
If the bank confirms that your account is eligible, ask which remaining step is preventing registration.
One App, Several Accounts
Open Banking can make managing multiple Korean bank accounts much easier.
But when a connection fails, the answer isn't automatically to change your English name, obtain another certificate, or visit every bank in Seoul.
First determine whether the problem lies with your identification records, authentication method, account eligibility, or app registration rules.
Then fix that specific problem.
With luck, you'll soon be checking several bank balances from one screen—just like your coworker.
And you can finally retire that little collection of banking-app passwords.
