Changing money at the airport sounds convenient — but in Korea, it can cost you. Exchange rates at Incheon International Airport are noticeably worse than what you’ll find in the city, and ATM fees add up fast. With a bit of planning, you can keep more won in your wallet from the moment you land.
What to Expect at Incheon Airport Exchange Counters
Incheon International Airport (ICN) has currency exchange booths in both Terminal 1 and Terminal 2, operated by banks including KEB Hana Bank, Shinhan Bank, and private exchange companies. They are open 24 hours in the arrivals hall, which is genuinely useful when you land at 2 a.m. and need cash for a taxi or limousine bus.
The catch: airport exchange rates typically offer around 70–80% of the mid-market (interbank) rate. On a USD 300 exchange, that could mean losing 30,000–50,000 KRW compared to what you’d get at a downtown Myeongdong or Hongdae money changer. For a two-week trip with a USD 1,000 budget, the gap can easily exceed 100,000 KRW (roughly USD 75).
That said, not all airport counters are equal. The private exchange booths near Exit 5 in the T1 arrivals hall sometimes post slightly better rates than the bank-run counters. Always check the board and compare before handing over cash.
The Smart Strategy: Exchange Just Enough at the Airport
The practical approach most experienced Korea travelers use is a two-step system:
- At the airport: Exchange only what you need for the first few hours — enough for airport transport and one meal. A good target is 50,000–100,000 KRW (about USD 35–75). This covers a limousine bus ticket or AREX express train to Seoul (17,000–18,000 KRW from T1 to Gangnam, or 9,500 KRW to Seoul Station), plus a convenience store snack.
- In the city: Exchange the bulk of your budget at a licensed private money changer in Myeongdong, Hongdae, or Insadong within your first day. These offer rates that are often 5–10% better than the airport, and better still if you bring crisp, unfolded USD 100 bills (the highest-denomination notes fetch the best rates).
Top-rated exchange spots in Seoul include the money changers clustered on the pedestrian street in Myeongdong (near the Myeongdong CGV cinema), the row of booths on Hongdae’s main drag near Hongik University Station Exit 9, and the exchange desks inside Lotte Department Store in Jamsil. Rates fluctuate daily, so it pays to check two or three counters before committing.
Using ATMs at Incheon vs. City ATMs
If you have a debit card from a bank with low foreign transaction fees (such as Charles Schwab, Wise, or Revolut), withdrawing KRW from an ATM can beat the exchange counter rate — but the details matter.
At Incheon Airport, Global ATMs (accepting foreign cards) are located in the arrivals halls of both terminals. The machines from KEB Hana Bank and Woori Bank are generally reliable. Expect a flat ATM fee of around 3,000–5,000 KRW per withdrawal from the Korean bank’s side, plus whatever your home bank charges. To minimize fees, withdraw a larger amount in one transaction rather than several small ones.
In Seoul, the most foreigner-friendly ATMs are the GS25 and CU convenience store ATMs (inside virtually every convenience store, 24/7), plus the dedicated Global ATM machines inside Citibank and KEB Hana Bank branches. Withdrawal limits vary by machine but typically cap at 700,000 KRW per transaction. If your card is on the Visa or Mastercard network, success rates are high. UnionPay and JCB cards also work at many machines, but always have a backup plan.
One important note: always choose to be charged in KRW, not your home currency, if the ATM asks. The “Dynamic Currency Conversion” option in your home currency locks in a poor rate set by the ATM operator — sometimes 5–8% worse than your own bank’s rate.
Practical Tips to Maximize Your Won
- Bring USD 100 bills in good condition. Worn, torn, or written-on bills are refused or exchanged at a penalty rate.
- Check the day’s reference rate at kr.exchange-rates.org before you travel so you know what a “good” airport rate looks like.
- T-money card (Korea’s transit card) can be topped up at all airport convenience stores — buy one at the airport for 4,000 KRW and load 20,000–30,000 KRW to cover buses and subway rides until you exchange the rest of your cash in the city.
- Kakao Pay and Naver Pay are widely used by locals but require a Korean phone number to set up — not useful for most tourists. Stick to cash and a no-fee international debit card as your dual strategy. Before you fly home, remember that unspent won can also be recovered through airport tax refund counters if you shopped at participating stores.
- If arriving in Busan via Gimhae International Airport (PUS), the same rules apply: exchange a small amount at the airport (KEB Hana Bank counter near arrivals) and do the bulk exchange at the Seomyeon or Nampo-dong money changers in the city.
Cash vs. Multi-Currency Card: Which Should You Rely On?
Most travelers ask whether they even need to bother with cash exchange at all if they have a Wise, Revolut, or similar multi-currency card loaded with won. The honest answer is that you need both, and the mix depends on how you travel.
A pre-loaded multi-currency card works well for card-friendly spending — convenience stores, chain cafes, department stores, and most restaurants in Seoul and Busan now accept contactless or chip cards without issue. If you convert money into KRW inside the app before you travel, you typically get a rate very close to the mid-market rate, which beats both airport counters and city money changers. This suits travelers who prefer not to carry much cash and who are comfortable topping up the app as they go.
Where cash still wins: traditional markets (Gwangjang Market, Namdaemun Market), small family-run restaurants, street food stalls, some taxis outside major cities, and temple donation boxes. Many of these simply don’t have a card reader, or the owner will ask for cash only. If your trip includes market food crawls or day trips to smaller towns, budget at least 30–40% of your daily spending money in cash — this is the kind of detail official bank or airport guides rarely mention, because it comes from what actually happens at the till, not what the payment network claims is “widely accepted.”
So who should choose which approach? If you’re spending most of your trip in central Seoul, Busan, or Jeju City and eating mainly at restaurants and cafes, lean on a multi-currency card for 70–80% of spending and carry only light cash as backup. If your itinerary includes rural areas, hiking trail food stalls, or older neighborhood markets, carry more cash than you think you need — running out of won in a small town at night, far from a 24-hour convenience store ATM, is a genuinely inconvenient way to end a travel day.
One more point worth flagging: some smaller money changers and even a few ATMs post a daily withdrawal or exchange limit that resets at midnight Korea time, not at a rolling 24-hour mark. If you’re planning a large exchange (say, over USD 500 in a single transaction), it’s worth asking the counter staff directly whether the day’s limit has already been affected by earlier transactions — this detail isn’t posted on any sign, but front-line staff will usually tell you if you ask. Prices and fees mentioned above reflect typical rates as of 2026 — verify current rates and limits before visiting, since both bank policies and exchange market conditions can shift.
