Opening a Korean Bank Account as a Foreigner

Opening a Korean bank account as a foreigner is rarely forbidden. A bank must verify three things before the account works normally: that you are who you say you are, that you live where you say you live in Korea, and that you have a documented reason for wanting the account. A passport settles the first and almost none of the second or third, which is why many foreign residents end up with an account that exists but cannot send their rent.

What does a Korean bank actually have to verify before opening your account?

실명확인, real-name verification. Under the Real Name Financial Transactions Act of 1993, an account must be held in a legally verified real name, and anonymous or borrowed-name accounts are prohibited. The clerk is not confirming that you exist; they are binding the account to an identity record Korean institutions can check.

Customer due diligence. Under the Financial Transaction Reports Act, which Koreans call 특정금융거래정보법, the Korea Financial Intelligence Unit requires a bank opening an account to verify real name, address and contact details and to establish the purpose and intended nature of the relationship. For foreign customers it specifically names nationality and domestic residence.

금융거래목적 확인, purpose-of-transaction verification. Before 2024 this was industry practice rather than law, and a regulatory review in August 2023 criticised it as a shadow regulation without statutory foundation. An amendment to 통신사기피해환급법, the special act on telecommunications-based financial fraud, then passed in February 2024 and took effect with its enforcement decree on 28 August 2024.

What follows at the counter depends on your evidence. A refusal to answer, or a purpose that looks linked to fraud, can get the account refused or closed. Documents that are merely thin get the account opened with restricted limits, which produces the “I have an account but it does not work” experience.

What documents do foreigners need to open a bank account in South Korea?

There is no single national checklist. The government’s plain-language legal portal on financial transactions for foreign nationals sets out categories, then states explicitly that requirements vary by bank and account type.

Identification: a residence card, a passport, or a home-country national ID.
Proof of the account’s purpose: for salary, an employment certificate or withholding tax receipt; for part-time work, an employment contract or pay stub; for business funds, transaction contracts or records of client payments; otherwise, objective documents supporting the purpose you state.
Tax documents where applicable: evidence of residence status, plus a foreign taxpayer identification number and overseas address.

Branches also commonly ask for a Korean mobile number and a verifiable Korean address. Ask your branch what it needs for your visa status before travelling there.

Do you need an 외국인등록증 to open a Korean bank account?

The 외국인등록증 is less a card than a registration. A foreign national intending to stay beyond 90 days registers at the immigration office covering their address, and that registration assigns a foreign resident registration number, which Korean systems index like a citizen’s resident registration number. Recent official English materials from the Korea Immigration Service call the physical document a residence card; most residents still say ARC.

That number is what banks and telecom providers are really waiting for, because it makes you addressable inside systems they already use. It is also why the card creates a sequencing problem: issuance takes weeks, a phone number is easier with the card, and an account is easier with the phone number. Note, though, that nothing above makes a residence card the only acceptable identification: some branches will open a restricted account for an unregistered passport holder, and whether yours will is a branch-level question.

What is a 한도계좌 and how do you lift the limit?

A 한도계좌, or limited-transaction account, is a normal deposit account with a daily ceiling on money leaving it. It was introduced in 2016 so that people who could not prove why they needed an account could get one instead of being refused. It is an accommodation rather than a penalty, though it does not feel like one when a transfer fails.

Since 2 May 2024 the Financial Services Commission has set the daily ceilings at:

3 million won at a teller window, up from 1 million won.
1 million won through internet and mobile banking, up from 300,000 won.
1 million won for ATM withdrawals and transfers, up from 300,000 won.

To lift the ceiling you return to a branch with a document evidencing the account’s purpose: an employment certificate, a pay statement, a lease, a utility bill in your own name, or a business registration certificate. The same announcement made banks publish representative documents by purpose at counters and online, and allowed employment and income to be verified through Korea’s public MyData system instead of paper. It runs the other way too: accounts previously used in fraud keep lower ceilings even after a freeze is lifted.

Can foreigners use Korean internet-only banks and mobile payment apps?

Partly. This is where general guidance ages fastest, so verify directly.

The officially verified position is narrow. The Ministry of Justice began issuing a mobile residence card in January 2025, and from 21 March 2025 six banks, Shinhan, Hana, iM Bank, Busan, Jeonbuk and Jeju, accepted it for in-branch business including opening an account, with six more expected to follow. At launch only Jeonbuk Bank supported it for non-face-to-face service, and the Korea Immigration Service notice frames remote use as something to be expanded gradually.

Beyond that, the honest general pattern: Korea’s internet-only banks and payment apps set their own foreigner eligibility and change it without notice. Some onboard residence-card holders remotely; others have repeatedly postponed a foreigner service. Eligibility also commonly depends on a Korean mobile line registered in your own name, because that line carries identity verification. Check the provider’s own eligibility page, and do not assume a traditional bank account unlocks every payment app.

Is purpose verification a reasonable trade-off, or a barrier to financial access?

It is genuinely both, and the Korean debate says so openly. These rules exist to stop 대포통장, accounts opened in one person’s name and handed to someone else, which are the operational infrastructure of Korean voice-phishing fraud. Account opening is one of the few points where that chain can be broken before money moves.

The case against the current calibration is equally concrete, and the 2023 review made it: purpose verification pushes the cost onto whoever has the least conventional documentation of income. The review named homemakers, young adults, the elderly and new business owners, and found the threshold for lifting a limit highest for the people least able to clear it. Foreign residents were not named there. But a new arrival with a valid identity and no Korean employment history sits in the same structural position, and nothing in the framework notices the difference between a newcomer and a risk.

Caveat, verified October 2026. Requirements for foreign residents differ by bank, by branch, by visa status and by account type, and they change. The government’s own guidance says so. Confirm with your intended bank, and for anything about registration or residence period with the immigration office covering your address or the Hi Korea portal.

FAQ

Can I open a Korean bank account with only a passport?

Sometimes, depending on the bank and branch. Government guidance lists a passport as acceptable identification, but the bank must still verify your Korean residence and the account’s purpose, so an account opened this way is likelier to carry restricted limits.

Why is my new Korean account limited to 1 million won per day?

Because it was probably opened as a 한도계좌 when your purpose documents were judged insufficient. FSC-set daily ceilings are 1 million won online and at ATMs, 3 million won at a window. Bring a document evidencing the account’s purpose to a branch to lift it.

How long does it take to get a residence card after arriving in Korea?

Issuance takes some weeks after you apply. Because banks and telecom providers usually want the registration number, plan the sequence rather than assuming the account comes first.

Is a Korean bank allowed to refuse me an account?

Yes, in defined circumstances. Under the 2024 amendment to 통신사기피해환급법, a bank may refuse or close an account if you decline to provide required information or if the declared purpose appears connected to telecommunications fraud. Thin documentation alone normally results in a limited-transaction account instead.

The real barrier is a documented purpose, not your nationality

Korea’s banking system is not slow for foreigners. It is fast because it assumes a verified identity and a documented purpose, and a newcomer has not had time to acquire either in a form Korean systems recognise. That changes what you prepare: not more identification, but evidence of why the account exists.
