Yes, but you need an alien registration number and a Korean address

Foreigners can open a bank account in South Korea, but the process differs from what South Korean citizens go through. Most banks require you to have an alien registration number (your foreigner registration ID), proof of a Korean address, and a valid passport. You do not need to be a permanent resident or have a work visa—tourist visas, student visas, and temporary work permits all may have access to. The catch is that some banks are stricter than others, and a few will turn you away if you cannot prove you will be in the country long enough to justify the account.

The timeline is usually same-day or next-day. You walk in with your documents, fill out forms in Korean or with help from staff, and leave with a debit card and account number. Some banks now offer English-language support or have staff who speak English, particularly in Seoul and other major cities. If you are opening an account remotely or before you arrive in Korea, that is much harder—most banks require you to show up in person with your passport and alien registration number.

Key Takeaways

  • You must have an alien registration number and a Korean address; a passport alone is not enough.
  • Tourist, student, and temporary work visas all allow you to open a bank account—you do not need permanent residency.
  • Major banks like KB Kookmin, Shinhan, and Woori accept foreigners more consistently than smaller regional banks.
  • The process takes one visit and usually one day, but you must show up in person with original documents.
  • Some banks charge monthly fees or require a minimum balance; compare terms before you choose.

What documents you need to bring

Your passport is the foundation, but it is not enough on its own. You also need your alien registration number, which you receive when you register with your local immigration office (usually within 90 days of arrival). If you have not registered yet, you cannot open an account at most banks—go to your nearest immigration office first, bring your passport and proof of address, and get your registration card.

Proof of a Korean address is the second requirement. This can be a lease agreement, a utility bill, a letter from your employer, or a certificate from your landlord. If you are staying in a guesthouse or short-term rental, some banks will accept a booking confirmation or a letter from the property owner. A few banks will also accept a letter from your employer stating your Korean work address, though this is less common.

Bring originals, not copies. Banks will photocopy what they need, but they want to see the real documents to verify they are genuine. If your documents are in English or another language, bring them anyway—staff will compare them to your passport and registration card to confirm the information matches.

Which banks accept foreigners most reliably

The five largest banks—KB Kookmin, Shinhan, Woori, Hana, and NH Nonghyup—have the most consistent policies for foreigners and the most English-speaking staff. These banks have branches in every major city and many smaller towns. If you walk into one of these banks with your passport, alien registration number, and proof of address, you will almost certainly be able to open an account.

Smaller regional banks and credit unions are less predictable. Some will open accounts for foreigners without hesitation; others will ask you to come back with a Korean co-signer or will refuse outright. If you are in a smaller city or rural area and the major banks are not nearby, call ahead before you visit. Many banks now have customer service lines with English speakers who can tell you whether they will open an account for you.

Online-only banks like Kakao Bank and Toss have made it easier for some foreigners to open accounts remotely, but they still require an alien registration number and a Korean phone number. The process is faster than visiting a physical branch, but you still cannot do it entirely before you arrive in Korea.

The step-by-step process at the bank

Walk into the bank during business hours (most are open 9 a.m. to 4 p.m. weekdays, some until 6 p.m., and closed on weekends). Tell staff you want to open a savings account. They will ask for your passport and alien registration number, verify the information, and hand you a form to fill out. The form asks for your name, address, phone number, and the type of account you want (most foreigners open a regular savings account).

You will choose a PIN for your account and decide whether you want online banking and a debit card. Most banks issue a debit card on the spot or within a few days. If you want to set up direct deposit from an employer or receive international transfers, tell the staff now—they can explain the process and give you your account number and bank code (needed for wire transfers).

The entire process takes 15 to 30 minutes. You will leave with your account number, a temporary card or a card that arrives by mail, and information about your bank's app and online banking system. Some banks charge a small fee to open an account (usually under 10,000 KRW, or about $8 USD); others do not charge anything.

Monthly fees and minimum balances

Most banks charge a monthly account maintenance fee of 2,000 to 5,000 KRW (roughly $1.50 to $4 USD). Some waive the fee if you maintain a minimum balance (often 100,000 to 500,000 KRW, or $75 to $375 USD) or if you set up direct deposit. A few accounts marketed to young people or students have no monthly fee at all.

Debit card fees vary. Using your card to withdraw cash at your bank's ATM is free; withdrawing at another bank's ATM usually costs 1,000 to 2,500 KRW per transaction. International transfers into your account are usually free, but sending money out of Korea can cost 10,000 to 20,000 KRW depending on the bank and the destination country.

Ask about fees before you open the account. The staff can show you a fee schedule, and most banks post their rates online. If you are only staying a few months, a no-fee account might be worth seeking out, even if it means going to a smaller bank or an online-only option.

What to do if a bank refuses you

If a bank says no, ask why. The most common reasons are: you do not have an alien registration number yet, your address proof is not acceptable, or the bank has a policy against opening accounts for people on tourist visas. If it is the first two, fix those and try again. If it is the third, move to a different bank—the major banks do not have this restriction, but some smaller banks do.

If you are on a tourist visa and multiple banks refuse you, consider opening an account at an online bank like Kakao Bank or Toss, which are more lenient about visa type. You can also ask your employer, school, or landlord whether they have a relationship with a specific bank that might help. Some employers can sponsor an account opening or provide a letter of introduction.

If you are staying long-term and plan to work, getting a work visa or long-term residence visa before you arrive will make the process smoother. Banks are more willing to open accounts for people on work visas than tourist visas, even though both are technically allowed.

International transfers and sending money out of Korea

Once your account is open, you can receive international wire transfers using your account number and your bank's SWIFT code (the bank will give you this). Transfers from the United States or Europe usually arrive within 2 to 5 business days and cost the sending bank a fee (you do not pay anything to receive money).

Sending money out of Korea is more expensive. A wire transfer to another country costs 10,000 to 20,000 KRW and takes 3 to 7 business days. Some banks charge extra if the receiving bank is in a country they consider high-risk. If you need to send money regularly, compare rates across banks or consider using a money transfer service like Wise or OFX, which are often cheaper than bank wire transfers.

Your debit card can be used at ATMs worldwide, but you will pay a foreign ATM fee (usually 1,000 to 2,500 KRW per withdrawal) plus any fee your home bank charges. For large amounts, a wire transfer is usually cheaper than multiple ATM withdrawals.

Frequently Asked Questions

Can I open a bank account on a tourist visa?

Yes, most major banks will open an account for you on a tourist visa as long as you have an alien registration number and proof of a Korean address. Some smaller banks or credit unions may refuse, so if one bank says no, try another. Online banks like Kakao Bank are generally more flexible about visa type.

What if I do not have a Korean address yet?

You need an address before you can open an account. If you are arriving soon, arrange temporary accommodation first—a guesthouse, Airbnb, or short-term rental. Once you have a booking confirmation or a letter from the property owner, most banks will accept that as proof of address. After you move to permanent housing, you can update your address with the bank.

How long does it take to get an alien registration number?

You must register with your local immigration office within 90 days of arrival. The process takes one visit and usually one day. Bring your passport, proof of address, and a completed form (available at the immigration office). You will receive your registration card immediately or within a few days, depending on the office.

Can I open an account before I arrive in Korea?

Not at most banks. You must show up in person with your passport and alien registration number. Some online banks may allow you to start the process remotely, but you will still need to verify your identity in person or through a video call once you arrive. Plan to open your account within your first week in Korea.

Do I need a co-signer or sponsor?

No, not for major banks. Some smaller banks or credit unions may ask for a Korean co-signer if you are on a tourist visa or have been in the country for less than a few months, but this is not standard. If a bank asks for a co-signer, try a different bank—you should not need one.
