You cannot fully open a Korean bank account online from outside South Korea, but you can start the process and complete it in person
Most Korean banks require you to visit a branch in person at least once to verify your identity and sign documents. Some banks let you open an account online if you already have a Korean phone number and resident registration number, but these accounts come with limits on what you can do. If you are a foreigner without a Korean address or ID number, you will need to go to a branch with your passport and proof of address.
The timeline and requirements depend on your residency status, whether you have a Korean phone number, and which bank you choose. Major banks like Shinhan, KB Kookmin, and Woori have slightly different rules, but all require at least one in-person visit for account opening.

What Korean banks require for online account opening
To start an account online, you need a Korean phone number and either a resident registration number or a valid passport. If you have a resident registration number—which means you are a citizen or have been granted long-term residency—you can open a basic account through most banks' mobile apps or websites without visiting a branch first. The app will ask you to verify your identity using your phone number and national ID information.
If you are a foreigner without a resident registration number, you cannot complete the full online process. You will need to visit a branch with your passport, visa, and proof of a Korean address. Some banks accept an employer letter instead of a residential lease if you do not have a signed rental agreement yet.
A few banks—including Shinhan and KB Kookmin—offer a hybrid process where you can fill out forms online and then schedule an appointment at a branch to complete verification. This saves time on the day you visit because the bank already has your information.
Which banks let you open accounts online and which require a branch visit
Shinhan Bank, KB Kookmin Bank, and Woori Bank all allow Korean citizens and long-term residents to open basic accounts through their mobile apps. Shinhan's app is considered the most straightforward for this process. These online accounts typically come with limits on daily transfers and monthly transaction volume until you visit a branch to upgrade them.
For foreigners, no major Korean bank lets you complete the entire process online. You must visit a branch. However, some banks let you pre-register online and upload documents before your visit, which speeds up the in-person appointment. Hana Bank and Shinhan have started offering this pre-registration option.
Smaller regional banks and online-only banks like Kakao Bank have different rules. Kakao Bank requires a Korean resident registration number and phone number but does not require a branch visit for basic account opening. However, Kakao Bank has lower transaction limits than traditional banks and does not offer all the services a foreigner might need.
Documents you need to bring to a branch
| If you are a | Bring these documents | Additional notes |
|---|---|---|
| Korean citizen | National ID card or passport, phone number | Can often complete online first; branch visit upgrades account limits |
| Long-term resident (F-2 visa or higher) | Passport, visa, resident registration number | Same process as citizens; can open online if you have registration number |
| Foreigner on work visa (E-1, E-2, F-2) | Passport, visa, proof of address (lease or employer letter) | Must visit branch; bring original and copy of each document |
| Foreigner on student visa (D-2) | Passport, visa, student ID or enrollment letter, proof of address | Some banks ask for school letter instead of residential lease |
| Foreigner on short-term stay (B-1, C-3) | Passport, visa, proof of address | Account opening may be denied; ask bank before visiting |
What happens during your in-person visit
The branch visit takes 10 to 30 minutes. A staff member will verify your identity by checking your passport or national ID, confirm your address, and have you sign account opening documents and a signature card. You will also choose your account type—most foreigners open a regular checking account (보통예금)—and set up online banking access and a PIN.
If you pre-registered online, the staff will confirm the information you already submitted and move straight to signing. If you did not pre-register, you will fill out a paper form first. Some banks ask you to set up a Korean phone number for two-factor authentication during this visit, so have your phone ready.
After you sign, the account is active immediately. You can withdraw cash from ATMs and make transfers the same day. Online banking access may take a few hours to activate, so do not be alarmed if you cannot log in right away.
Transaction limits on online-opened accounts
If you open an account entirely online without visiting a branch, most banks impose daily transfer limits of 1 to 5 million won and monthly limits of 10 to 20 million won. These limits exist because the bank has not verified your identity in person. Once you visit a branch and upgrade your account, these limits are removed.
Kakao Bank and other online-only banks may have permanently lower limits even after verification, so check the bank's current policy before opening an account if you plan to make large transfers. Traditional banks like Shinhan and KB Kookmin remove limits entirely once you visit a branch.
How long the process takes from start to finish
If you are a Korean citizen or long-term resident opening an account entirely online, the process takes 5 to 10 minutes through the mobile app. Your account is active immediately, though online banking access may take a few hours.
If you pre-register online and then visit a branch, the total time is the time to fill out the online form (5 to 10 minutes) plus the branch visit (10 to 30 minutes). You can schedule the branch appointment through the app, and most banks offer same-day or next-day slots.
If you are a foreigner visiting a branch without pre-registering, budget 30 to 45 minutes. Bring all documents in original and photocopy form to avoid delays. Some branches are slower than others; visiting during off-peak hours (mid-morning on a weekday) usually means shorter waits.
Frequently Asked Questions
Can I open a Korean bank account if I do not have a Korean phone number yet?
No, you need an active Korean phone number to open an account online. If you are a foreigner, you can get a prepaid phone number from any convenience store or phone shop for about 10,000 won, then use it immediately. For the in-person branch visit, you do not need a Korean number—your passport is enough.
What if my visa is expiring soon—can I still open an account?
Most banks will open an account if your visa is valid on the day you apply, even if it expires in a few months. However, some banks may deny the application if your visa expires within 30 days. Call the branch ahead of time to ask about their policy for your specific visa type before you visit.
Do I need to visit a branch in person if I already have a Korean bank account at another bank?
No. If you already have an account at one bank and your identity is verified in their system, some other banks will let you open a second account online without a branch visit. Ask the new bank whether they can cross-verify with your existing bank. This varies by bank and is not may provide.
Can I open a Korean bank account if I am visiting on a tourist visa?
Most banks will not open an account for someone on a tourist visa (B-1 or C-3). These visas are considered temporary and do not give you the legal status banks require. If you are planning to stay longer, you should change your visa status first. Ask the bank directly before visiting, as policies vary.
What is the difference between opening an account online and pre-registering online?
Opening an account entirely online means you complete the whole process through the app and never visit a branch—only possible if you have a Korean resident registration number. Pre-registering online means you fill out forms and upload documents through the app, then visit a branch to verify your identity and sign in person. Pre-registration saves time at the branch but does not replace the in-person visit.
