Before you start

An Alien Registration Card, physical or mobile, for a full account
A Korean mobile number in your own name, matching the ARC exactly
Proof of your Daegu address if the ARC address is out of date
A document proving the account's purpose — payroll, enrolment or a lease

Step-by-step

1
Open a passport-only account only if you need cash access now
Shinhan, Woori, Hana, KB and iM branches with a foreign desk will often open a limited account on a passport. It receives and pays out cash and does nothing else — no transfers, no online banking, no remittance abroad. It is a stopgap to be upgraded, not an account.

2
Get the ARC and a Korean number in your own name first
The dependency is circular if you attack it in the wrong order: the account wants a Korean number for identity verification, and postpaid phone plans want the ARC and often a Korean account. The order that works is ARC, then a prepaid or MVNO line in your own name, then the full account.
In personWho: You3–6 weeks for the ARC
3
Open the full account, and consider iM alongside a national bank
Bring the ARC, passport, Korean phone and a small opening deposit, and ask for the foreign or global desk. iM Bank has the densest branch network in the city, is the main bank for many local employers and landlords, and accepts the mobile ARC — while Shinhan's global service has the stronger English app. Plenty of residents end up holding one of each.

4
Clear the limited-transaction cap in the same visit
Anti voice-phishing rules open new accounts capped around ₩1 million a day for ATM withdrawals and transfers. An employment certificate, payslip, tuition invoice or lease is what lifts it. Bring one to the opening appointment and you often avoid the cap entirely rather than returning later.

5
Take a check card and a transit function
A check card debits your account directly and is accepted almost everywhere. Korea is close to cashless and foreign-issued cards are declined more often than newcomers expect — at kiosks, transit top-up machines and delivery apps in particular. Many check cards include the transit function; ask for one that does.

6
Set up the deposit account you will need at lease time
Korean rental deposits move as a single large transfer, and a brand-new account under a daily cap cannot make one. If a lease signing is coming, tell the branch and get the cap lifted in advance. This is the single most common reason a Korean rental falls through at the last moment for a foreign tenant.

Things most newcomers don’t know

The new-account daily cap collides directly with paying a Korean rental deposit.

Deposits move as one large transfer, often ₩10 million or more even for a modest flat, and a limited-transaction account capped around ₩1 million a day physically cannot make that payment. Tenants discover this on signing day with an agent and a landlord waiting. Tell the bank a lease is coming and lift the cap with a document beforehand — it is a five-minute conversation weeks earlier.

Daegu's local bank became a nationwide commercial bank in 2024, the first conversion in over three decades.

iM Bank, previously DGB Daegu Bank, now operates as a national commercial bank while keeping its dense home-city branch network. It is also one of the banks accepting the mobile Alien Registration Card. For a resident that combination is practical: local branch density and local employer relationships without being confined to a regional institution.

The name on your phone account must match the ARC character for character.

Real-name verification compares your name, birth date, phone number and registration number against carrier records as strings rather than as a person. A middle name recorded on one and dropped on the other, or a hyphen in a different place, fails with an error message that explains nothing. The phone contract is usually created last, so it is the one to police at the counter.

A Korean check card is close to mandatory rather than convenient.

Korea is one of the most card-dependent economies anywhere and the usual expat assumption inverts: it is the foreign card that gets declined, at transit machines, unmanned kiosks, delivery apps and small restaurants. Cash is a weak fallback because many places now handle it badly. Get the check card issued at the account-opening appointment rather than later.

Common mistakes to avoid

Signing a lease before lifting the new-account daily cap, and being unable to transfer the deposit.
Expecting a full, transfer-capable account on a passport before the ARC arrives.
A name mismatch between passport, ARC and phone contract breaking real-name verification.
Waiting out the daily cap instead of producing a proof-of-purpose document.
Relying on a foreign card for daily spending and transit top-ups.
