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- Proof of your Ulsan address if the ARC address is out of date, or a company housing assignment letter
- A document proving the account's purpose — payroll, enrolment or a lease
Step-by-step

Open a passport-only account only if you need cash access now
Shinhan, Woori, Hana, KB, NH and BNK Busan Bank 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.

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.

Let payroll tell you which bank to use, then add one of your own
Large Ulsan employers typically have a payroll relationship with a particular bank and will steer you to it, which is genuinely the path of least resistance for getting paid. It is worth also holding an account at a bank whose English app you can actually use, because payroll convenience and daily usability are frequently different institutions.

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 — and note this cap also blocks a normal monthly remittance home.

Sort outward remittance properly rather than by default
This is where the money actually goes in Ulsan. Compare your bank's telegraphic transfer fee and exchange spread against the licensed non-bank remittance operators, which are legal in Korea, regulated, and usually cheaper on small monthly sums. Ask the branch to register a designated overseas recipient — once set up, repeat transfers get simpler and the documentation burden drops.

Take a check card and set up the lease transfer before you need it
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. And if a lease signing is coming, tell the branch — a rental deposit moves as one large transfer that a capped new account cannot make.

Things most newcomers don’t know
In Ulsan the remittance spread costs more over a contract than every other banking decision combined.
A large share of the city's foreign workforce sends money home monthly, and the difference between a bank's telegraphic transfer plus spread and a licensed non-bank remittance operator compounds over two or three years into a serious sum. Korea licenses and supervises small-sum overseas remittance businesses, so the cheaper route is a regulated one rather than a grey one. Comparing them takes an evening and is the highest-return hour in this guide.

The new-account daily cap blocks both your rental deposit and your first remittance.
Anti voice-phishing rules cap a new account around ₩1 million a day for transfers, which is below both a Korean rental deposit and a typical monthly remittance. People discover it on lease-signing day or on their first payday. An employment certificate or lease produced at the account-opening appointment usually avoids the cap altogether.

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.

Company housing changes what proof of address you can produce.
If your employer assigns you accommodation rather than you signing a lease, you will not have the lease document that banks, carriers and immigration all expect. The substitute is the employer's housing assignment letter plus your ARC address. Ask HR for it in Korean on company letterhead when you arrive, rather than discovering at three separate counters that you cannot prove where you live.

Common mistakes to avoid
- Defaulting to your bank's telegraphic transfer for every monthly remittance without comparing licensed operators.
- 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.
- Living in company housing without obtaining a written address confirmation from your employer.
- A name mismatch between passport, ARC and phone contract breaking real-name verification.
