Yes, foreigners can open a bank account in South Korea, but the process differs from what Korean citizens do

Most major South Korean banks will open an account for a foreigner, but you need an Alien Registration Number (ARN) first — a registration ID issued to non-citizens staying longer than 90 days. Without it, you cannot open a regular account at most banks. If you are staying fewer than 90 days, some banks offer limited accounts, but these come with restrictions on transfers and deposits.

The banks most likely to work with foreigners are the large ones: KB Kookmin Bank, Shinhan Bank, Woori Bank, and NH Nonghyup Bank. Smaller regional banks may refuse or require more documentation. You will need your passport, proof of residence (a lease agreement or utility bill), and your ARN or proof that you have applied for one.

The entire process usually takes one to two weeks from the time you have all documents in hand, though account opening itself happens the same day you visit the branch.

Key Takeaways

  • You must have an Alien Registration Number to open a regular account at most South Korean banks, which requires staying longer than 90 days.
  • Large national banks like KB Kookmin, Shinhan, and Woori are more likely to accept foreigners than smaller regional banks.
  • You will need your passport, proof of residence, and your ARN or proof of application; bring originals and copies of both.
  • If you are staying fewer than 90 days, some banks offer short-term accounts with limited transaction amounts and transfer restrictions.
  • Account opening happens the same day at the branch, but receiving your debit card and full access takes one to two weeks.

Getting an Alien Registration Number before you open an account

The Alien Registration Number is issued by the Korea Immigration Service and is required for any non-citizen staying longer than 90 days. You obtain it at your local immigration office (called a "branch" or "sub-office" depending on your city) by presenting your passport, a completed application form, and proof of residence such as a lease or utility bill.

Processing takes about one week. Once you have the ARN, you can take it to any bank branch. If you are still waiting for your ARN, most banks will accept a receipt showing you have applied, though some branches may ask you to return once the actual number arrives.

If you are staying fewer than 90 days, you do not need an ARN, but your account options are limited. Short-term accounts typically cap monthly transfers at 10 million won and daily withdrawals at 5 million won, though these limits vary by bank.

What documents to bring to the bank

Bring your passport (original and a copy), your Alien Registration Number card or receipt of application, and proof of residence. Proof of residence can be a lease agreement, a utility bill in your name, or a letter from your employer or school confirming your address. Some banks also accept a letter from your landlord.

If your documents are in another language, bring both the original and an official Korean translation. Many banks have translators on staff or can direct you to a certified translator nearby, but bringing a translation yourself speeds things up.

You will also fill out an account opening form at the bank. This form asks for your name, date of birth, address, occupation, and the purpose of the account. Be honest about the purpose — banks ask this for compliance reasons, not to judge you.

Which banks accept foreigners most readily

The four largest banks — KB Kookmin, Shinhan, Woori, and NH Nonghyup — have the most experience with foreign customers and the clearest policies. They have English-speaking staff at most major branches, and their websites often have information in English about opening an account as a foreigner.

Smaller regional banks and credit unions (called "savings banks") are less predictable. Some will open accounts for foreigners; others will not. If you call ahead and ask, they will usually tell you whether they can help. Do not assume a branch will refuse just because it is small — some smaller branches are more flexible than large ones.

International banks like HSBC and Citibank operate in South Korea but typically require a minimum deposit (often 10 million won or more) and are aimed at expat professionals, not casual visitors or short-term residents.

Timeline from application to first use

The day you visit the bank with your documents, the account opens immediately. You receive a temporary card or passbook that you can use to make deposits and withdrawals at that branch's ATM the same day.

Your actual debit card arrives by mail within one to two weeks. During this waiting period, you can still access your account through the bank's mobile app (which you download and set up at the branch) or by visiting the branch in person. Online transfers and bill payments through the app are usually available within a few days of opening the account.

If you need the card faster, some branches can issue a temporary card on the spot, though this is not may provide. Ask when you visit.

Restrictions and fees for foreign account holders

Foreign account holders face the same monthly fees as Korean citizens — usually 0 to 2,500 won per month depending on the bank and account type. Some accounts waive fees if you maintain a minimum balance or receive direct deposits.

The main restriction is on international transfers. Sending money out of South Korea requires additional documentation: a copy of your passport, proof of the transfer's purpose, and sometimes proof of income or employment. Receiving money from abroad is simpler and usually has no restrictions.

Some banks limit the number of free transfers per month (typically 5 to 10) before charging per transaction. Check with your specific bank about their transfer policy before opening the account.

What to do if a bank refuses to open an account for you

If a bank refuses, ask why. Common reasons are that you do not yet have an ARN, your proof of residence is not acceptable, or the branch has a policy against short-term residents. If it is the ARN, you can either wait for it to arrive or ask the bank if they accept the application receipt.

If it is the proof of residence, ask what documents they will accept. A lease is strongest; a utility bill works; a letter from your employer or school is usually accepted. If you are staying with a friend, ask your friend to write a letter on their letterhead confirming you live there, and bring a copy of their lease or utility bill as backup.

If a branch simply refuses to work with foreigners, try a different branch of the same bank or a different bank entirely. Large branches in central business districts are more likely to have experience with foreigners than small neighborhood branches.

Frequently Asked Questions

Do I need a Korean phone number to open an account?

Most banks ask for a phone number but do not require it to be a Korean number. A foreign number works, though some banks may ask for a Korean number for SMS notifications. If you plan to stay more than a few weeks, getting a Korean phone number (which is inexpensive and takes one day) makes banking easier because many services send verification codes via SMS.

Can I open an account online without visiting a branch?

No. All banks require you to visit a branch in person and show your passport and ARN. Some banks offer online account management after opening, but the initial account must be opened face-to-face.

What happens to my account if I leave South Korea?

Your account remains open. You can continue to use it for transfers and bill payments from abroad through the bank's app or website. If you do not use the account for a long period (usually two to three years), the bank may freeze it, but you can reactivate it by visiting a branch or calling customer service.

Can I open a business account as a foreigner?

Business accounts have stricter requirements and vary by bank. You typically need a Korean business registration number, which requires establishing a business entity in South Korea. This is more complex than opening a personal account and usually requires a Korean accountant or lawyer to help. Contact the bank directly to learn their specific requirements.

What if my ARN application is rejected?

ARN applications are rarely rejected if you have a valid passport and proof of residence. If yours is rejected, the immigration office will tell you why — usually because your proof of residence is not acceptable or your stay period does not may have access to. You can reapply with different documents or ask the immigration office what they need.
