Opening a Bank Account in Korea as a Foreign Resident

What to bring

Most branches will ask for:

• Alien registration card — the central document. Without it, options narrow sharply
• Passport
• Korean mobile number — needed for authentication, and banks generally will not accept a foreign number
• Proof of purpose — employment contract, certificate of enrolment, or a lease

The circular problem for new arrivals is that a phone contract often wants a bank account and the account wants a phone number. The usual sequence is: prepaid SIM → alien registration card → bank account → postpaid phone plan.

Some banks will open a restricted account for a new arrival holding only a passport, typically with tight limits and a requirement to return once registered. Ask rather than assume — practice differs by bank and by branch.

Why your transfers are capped

Almost every new account in Korea is opened as a limited-transaction account. This is a fraud-prevention measure applied to residents and foreigners alike, introduced to make it harder to open accounts for use in voice-phishing operations.

In practice you get daily caps on ATM withdrawals and on electronic transfers. The caps are low enough to be inconvenient — paying a deposit or a large invoice will not go through.

This is not a judgement about you, and branch staff cannot waive it on request. It is lifted by evidence of a genuine banking need, typically one of:

• Salary deposit — a payslip plus employment certificate, or a few months of salary credits
• Lease contract showing you need to move rent or a deposit
• Certificate of enrolment for students, with tuition payment records
• Sustained normal activity over several months

Bring the evidence to a branch and ask for the limit review. Doing it at the branch where you opened the account is usually smoother.

Choosing a bank

Practical differences for foreign residents:

Major commercial banks (KB Kookmin, Shinhan, Woori, Hana, NH Nonghyup) Broadest branch and ATM coverage. Several operate branches near foreign-resident concentrations with English-speaking staff, and their apps offer English interfaces of varying quality. Shinhan and KB are commonly recommended for English support, though this varies by branch more than by brand.

Internet-only banks (Kakao Bank, K Bank, Toss Bank) Strong apps, low fees, no branches. Eligibility for foreign residents has expanded but is not universal, and onboarding is identity-verification heavy — which is precisely where foreign residents hit friction. Worth trying once your registration and phone number are settled.

Post office banking Wide rural coverage, useful outside metropolitan areas.

A reasonable pattern is a major bank as the primary account for salary and rent, and an internet bank added later for day-to-day convenience.

Check the fee schedule for international transfers if you plan to send money home — the differences between banks are larger there than on domestic services.

Setting up the account properly

Ask for these at opening, or you will be back:

• Internet and mobile banking registration — often a separate step
• Security medium — a certificate, OTP card or app-based authentication. Ask which one their app actually supports
• Debit or check card — issued on the spot at many branches
• English SMS alerts, if offered
• Automatic transfer setup for rent and utilities

The authentication certificate deserves attention. Korean banking still leans on certificate-based verification, and how it is installed and where it is stored determines whether you can bank from your laptop or only your phone. Have staff walk you through it while you are at the counter.

When you leave Korea, close accounts properly. Dormant accounts and unresolved balances complicate things if you return, and closing usually requires a branch visit that cannot be done from abroad.
