You have your Alien Registration Card, a Korean phone number, and a lease that wants a deposit by Friday. You walk into a bank, take a number, wait twenty minutes, sit down — and the first question is not “which account would you like?” but “what will you use this account for?”
That question is the key to the whole process. Opening a bank account in Korea as a foreigner is very doable, usually in under an hour. But the rules are built around stopping phone scams, not around welcoming newcomers, and the guides online are full of limits and app names that changed years ago. This is the version I give friends who move here.
What to bring
For a regular account at any of the big banks, bring:
- Your Alien Registration Card (ARC). This is the document that matters. If you’re still waiting for it, most people find it easier to wait than to fight for a passport-only account.
- Your passport.
- A Korean phone number in your own name. Banking apps verify you by text message to a number registered to you. A prepaid tourist SIM or a friend’s line usually won’t work.
- Proof of why you need the account. A certificate of employment (재직증명서) or a recent pay slip if you’re working. If you’re a student, ask whether your enrollment certificate counts. This is the document most guides forget, and it decides how useful your account is on day one.
The order that saves the most time is: ARC first, then a phone contract in your name, then the bank. If you’re still sorting out the phone, our guide to getting a SIM card in Korea covers it.
The limit nobody warns you about
Almost every newcomer hits this. If you open an account without proving what it’s for, the bank opens it as a limited account (한도제한계좌, sometimes translated as a “financial transaction limit account”). It’s a voice-phishing measure: new accounts are the easiest ones for scammers to use, so they start with daily caps.
Since May 2024 those caps are:
- ₩1,000,000 a day in online and mobile transfers
- ₩1,000,000 a day from ATMs
- ₩3,000,000 a day at the bank counter
You will still see guides quoting ₩300,000. That was the old limit. One million won a day is livable, but it gets tight the week you pay a housing deposit.
How to lift it: show the bank the account’s purpose. For salary, that’s a certificate of employment, pay slips, or a withholding tax receipt. Some banks will also lift it once the account has a few months of regular automatic payments (rent, phone bill, utilities), and some let you apply inside the app. Each bank sets its own criteria, so ask at the counter what they’ll accept. The easiest route is to bring the documents on day one and say clearly, “This account is for my salary.”
What happens at the branch
1. Take a number (번호표) from the machine by the door. Choose the general banking option, not loans or business. 2. When you’re called, say you’d like to open an account. Staff at bigger branches usually manage basic English. 3. Hand over your ARC, passport, and proof of purpose. You’ll be asked what the account is for and about your stay in Korea. That’s routine verification, not suspicion. 4. Sign a stack of forms. Many banks have English versions. 5. Most branches issue a debit (check) card on the spot. 6. Before you leave, ask them to set up the mobile app with you. App registration, security codes, and identity checks are much easier with a teller beside you than alone at home.
Plan on 30 to 60 minutes. Weekday mornings are quietest, and branches near universities, large offices, or foreigner-heavy neighborhoods tend to have staff who do this every day.
Which bank should you choose?
Honestly, the bank matters less than people think. The four big commercial banks — KB Kookmin, Shinhan, Hana, and Woori — all open accounts for ARC holders, all have ATMs everywhere, and all connect to the payment apps you’ll actually use day to day. What differs is the branch you walk into and how comfortable you are in their app.
A practical way to choose:
- Use your employer’s or university’s bank if they have one. Payroll and tuition are simpler, and the nearby branch is used to foreign staff or students.
- Pick the branch you can reach, not the bank with the best reviews. You’ll go back for card replacements, limit changes, and app problems.
- Check the app. Hana runs a separate app for foreign customers called HanaEZ, and Shinhan’s SOL app is the one foreigners mention most for English support. If English matters to you, open the app store listing before you choose.
Mobile-only banks are a real option once you have an ARC. Toss Bank has let ARC holders open accounts entirely online since 2022, and KakaoBank opened its app to foreign residents this year. They’re excellent for daily spending and transfers. Many people keep one big-bank account for salary and rent and a mobile account for everything else.
After the account is open
Within a day or two, link your account or debit card to the payment apps everyone uses — that’s when Korean daily life really opens up. Rent, phone bills, and utilities can all be set to automatic payment, which also helps lift the account limit.
Two related guides pick up from here:
- Sending money home or receiving it from abroad: how to send money from Korea abroad.
- Where to keep savings once you’re settled: savings accounts in Korea for foreigners.
The quick version
Get your ARC first, then a phone number in your own name, then go to the bank with your passport and a document that proves what the account is for, such as a certificate of employment. Without that proof, your account starts with daily limits of ₩1 million online and at ATMs and ₩3 million at the counter. Any of the big four banks will do. Choose the branch you can reach and the app you can read, and ask the teller to set up the app before you leave.
Bank rules for foreigners change often, and each bank applies them a little differently. If your branch asks for something not listed here, that’s normal — ask what they need and bring it next time.
