Opening a bank account in Korea as a foreigner: what you need and what changed

This guide is for foreign nationals living in, working in, or planning to move to Korea who need a local bank account. The short answer: bring your Residence Card (the document most people still call the ARC) and your passport to any major bank branch, and you can open an account the same day — but almost every new account starts with daily transfer limits that stay until you show proof of purpose.

How it works

What you need to bring

Korean banks require two primary documents from foreign nationals.

• Residence Card (RC) — officially renamed from Alien Registration Card (ARC) in 2024, though most banks and residents still use the old name. The card is issued by the Ministry of Justice after you register your address in Korea, typically two to four weeks after arriving on a long-term visa. Since January 10, 2025, the Ministry of Justice has also issued a mobile Residence Card on smartphones; since March 21, 2025, six domestic banks — Shinhan, Hana, iM, Busan, Jeonbuk, and Jeju — accept the mobile card for account opening (source: Financial Services Commission press release, March 2025).
• Passport — your original document, not a copy.

Depending on your visa type, a teller may also ask for a supporting document that shows why you need the account: an employment contract, an enrollment certificate (for students), or a lease agreement. This is not always required on the first visit, but having one ready speeds up the process.

Visitors and tourists

If you are in Korea on a short-term tourist visa, you cannot get a Residence Card and most branches will not open a standard account without one. A small number of branches — primarily at Woori Bank — will open a passport-only account, but it comes with severe restrictions and cannot receive salary deposits or make large transfers. The practical option for tourists is to use overseas mobile-payment services linked into Korea’s Zero Pay QR standard, such as Alipay, WeChat Pay, or UnionPay, which work at millions of merchants without a Korean bank account.

Limited accounts and how to lift the limits

To combat voice-phishing (telephone fraud) and money-mule schemes, Korean banks open virtually every new account as a limited account (한도계좌, hando gyejwa). A limited account has a daily transfer and withdrawal ceiling in the range of 1 million won (approximately USD 740 at mid-2026 rates), which applies even if a salary has already been deposited.

To lift the limits, return to the branch and present one or more of the following:

• An employment contract or payslips in your name
• A lease agreement (jeonse — a large lump-sum deposit paid instead of monthly rent — or monthly rent contract)
• A utility bill in your name
• An enrollment certificate if you are a student

The bank verifies the document and upgrades the account on the spot. There is no fee.

Online banking and digital certificates

Activating a Korean bank’s mobile app requires a Korean mobile phone number registered in your name. Without one, you can hold a passbook and a physical debit card, but remote access is not available.

For higher-value transfers through online banking or government portals, Korean systems use a digital authentication certificate. The older public-key certificate system (공인인증서, gong-in injeung-seo) has been progressively replaced by private-sector certificates issued directly through bank apps, backed by biometric or PIN authentication. Most major banks now let you complete the full certificate setup inside their app after your mobile number is verified. If you are asked to use a legacy government portal, your bank can guide you through obtaining the appropriate certificate type.

International transfer registration

To send money abroad regularly, you must designate a foreign exchange bank. For transfers above USD 5,000 per transaction, the designation must be made in writing at the branch. Once designated, you can remit up to your annual personal limit without submitting a supporting document each time. For larger or purpose-specific transfers, the bank will request documentation such as proof of property purchase or tuition payment.

From 2026, Korea is rolling out the Overseas Remittance Integrated System (ORIS), which consolidates the annual remittance limit across all banks rather than tracking it per institution. This means your cumulative outbound transfers — across every bank you use — count toward one shared annual ceiling.

Why Korea does it this way

Korea’s real-name financial system (금융실명제, geumyung silmyeong-je), introduced in 1993, requires that every account be linked to a verified legal identity. This was designed to reduce tax evasion and illicit capital flows. The system was later strengthened with anti-money-laundering rules, which are the legal basis for limited accounts today.

The foreign exchange controls trace to the 1997–1998 Asian financial crisis, when a sudden capital outflow caused the won to collapse and Korea had to seek an International Monetary Fund bailout. The Foreign Exchange Transactions Act, revised multiple times since then, sets the rules for how residents and non-residents move currency across Korea’s borders. The Bank of Korea oversees the foreign exchange framework; commercial banks execute it.

The deposit insurance system is run by the Korea Deposit Insurance Corporation (KDIC), a government body established under the Depositor Protection Act.

The numbers that matter

What it means for you

If you are starting a new job

Open your account as soon as your Residence Card arrives. Bring your employment contract to the branch at the same time so the teller can lift the limited-account restrictions immediately. That way, your first salary arrives into a fully functional account. If you open the account before the contract is signed, go back once you have it — do not wait for a problem to appear.

If you are renting

Your lease agreement — whether a jeonse deposit contract or a monthly rent contract — counts as proof of purpose and will lift your limited-account ceiling. Keep a physical copy; bank tellers may not accept phone photos of documents at all branches.

If you send money home regularly

Designate your primary bank as your foreign exchange bank early. This one administrative step — done once at the branch — allows you to remit up to USD 50,000 per year (as of mid-2026; verify the current figure at bok.or.kr) without presenting fresh documentation each time. Transfers above USD 5,000 require the designation to be on record. Under the new ORIS framework rolling out in 2026, the annual ceiling is tracked across all banks, so splitting transfers across multiple institutions no longer resets the counter.

If you invest in Korea

Buying Korean securities as a foreign resident requires a separate investor registration with the Financial Supervisory Service (FSS). A bank account alone does not give you trading access. Consult the FSS or a licensed securities firm for the current registration steps.

FAQ

Can I open a Korean bank account without a Korean phone number?

You can open an account and receive a passbook and a debit card without a Korean number. However, you will not be able to activate mobile banking, make online transfers, or use most government digital services. A Korean SIM registered in your name — either through a local carrier or a foreigner-specific MVNO plan — is effectively a prerequisite for using the account beyond cash withdrawals.

What happens to my account if my visa expires or I leave Korea?

A Korean bank account does not automatically close when your visa expires, but banks are required to flag accounts whose Residence Card details are no longer current. If you leave Korea permanently, notify your bank and transfer remaining funds before departure. Dormant accounts with small balances may be transferred to a dormant-account management scheme after a defined period of inactivity; contact your bank for its specific policy.

Is my money safe in a Korean bank?

Deposits at Korean banks, savings banks, insurance companies, and licensed financial investment firms are protected by the Korea Deposit Insurance Corporation up to KRW 100 million per depositor per institution, covering both principal and interest, effective September 1, 2025. Amounts above that threshold are not insured by the KDIC. Foreign-currency deposits may have different coverage rules — ask your bank for written confirmation of what is covered.
