Your first 30 days
Korean money life is a chain: the phone unlocks the ID, the ID unlocks the bank, the bank unlocks everything else. Here’s the order that works — and how much money to have while you build that chain.
Every number here is yours. The tool adds them up and puts a safety buffer on top. If you don’t know a number yet, that’s the one to go get a real quote for.
| One-time cash (move-in + setup) | 300,000 KRW |
| Living until first pay | 2,071,346 KRW |
| Safety buffer (15%) | 355,702 KRW |
| Total to land with | 2,727,048 KRW |
A planning estimate from the numbers you enter. No cost-of-living averages are built in, and nothing you type is stored. Prices and deposits vary a lot by city and situation, so replace the defaults with real quotes.
The order that unlocks everything
Most first-month frustration comes from doing things in the wrong order — walking into a bank on day two, or waiting on a payment app that can’t verify you yet. The chain below is the one that actually works.
How much money should I land with?
Enough to cover three buckets: one-time move-in cash (the deposit is the big one), one-time setup (SIM, household basics), and weekly living costs until your first salary. That salary often lands six or more weeks after you do.
Why is that? Korean salaries are usually paid monthly, and the payroll cutoff means a mid-month start often pays out the following month. Meanwhile the deposit and first rent go out together in week one. Money out first, money in later: that mismatch is the entire first-month problem.
A working number isn’t the same as one that verifies you
A prepaid SIM takes only your passport. Buy one at the airport or a convenience store, and you’re reachable on day one. But it has one hard limit: Korean apps verify identity through a phone line registered to your ID, and a passport-registered prepaid line usually can’t do that.
Why is that? Banks, payment apps, and government sites lean on phone-based identity verification (본인인증). It checks that the phone line is registered to the same ID you’re signing up with. Until your line is tied to your residence card, you have a working phone that can’t vouch for you.
The 90-day ARC clock
Staying more than 90 days? You have to register and get a residence card (외국인등록증, often still called the ARC). You apply in person at an immigration office, and you book that visit on HiKorea. The 90-day deadline is about the visit, not the card. The card itself commonly takes weeks more to arrive.
Why is that? Appointment slots fill up fast in arrival seasons, and the card is the key to almost everything financial: full banking, phone verification, contracts. Every week you wait to book pushes the whole chain back. So book in week one, even if the appointment itself lands weeks later. Processing times vary by office, so treat any timeline you read as a guess. The receipt from your own appointment is what to go by.
Your first account comes with training wheels
With the residence card in hand, opening an account is straightforward. Expect it to start as a restricted account (한도제한계좌) with low transfer limits until the bank has seen a salary, a purpose, and a paper trail.
Why is that? Korean banks apply anti-fraud limits to fresh accounts, and foreigners hit them hardest because there’s no local history yet. The limits loosen as evidence builds up: an employment contract, salary deposits, and time. Plan around it. Don’t schedule a big transfer for the week the account opens.
Salary, insurance, housing — what starts on its own
Once the account exists, the system starts moving without you. Payroll takes out tax and social insurance before you see the money, and health insurance enrolls you on its own clock: through work if you’re employed, and automatically after six months for most other residents.
Why is that? The deductions on your payslip (pension, health, employment insurance, income tax) are the default, not an error. Knowing that in advance saves you the usual first-payday shock: why is my salary smaller than my contract? Housing is the opposite: nothing there is automatic, and protecting the deposit is on you — a 확정일자 (fixed-date) stamp on your lease plus your address report (체류지 변경신고 for foreign residents), which the housing guide walks through.
Common terms
Questions new arrivals ask
Sometimes, with a passport. But expect limits, and many branches will just ask you to come back with the card. A realistic plan is to live on a foreign card and some cash first, then open the account properly once the card is in hand. The banking guide covers what each path needs.
Not usually. The domestic payment apps need a Korean bank account and phone-based identity verification. That verification only works on a phone line registered to your residence card. For most people it all falls into place somewhere in weeks 3–6, not on day one.
No. It just moves differently. A foreign card works at most staffed shops, ATMs marked “Global” give you cash, and a prepaid card covers transit and small payments. The visitor pages cover that survival kit; this page is about building the permanent setup.
