Exchanging money in Korea is one of those tasks that can either go smoothly or cost you a surprising amount if you do not know the landscape. Here is what actually works — and what to avoid.
Where to Get the Best Exchange Rates in Korea
The single best exchange rate you will find in Korea is at the independent money changers in Myeongdong, Seoul. These small booths — not banks, not hotels — consistently offer rates 3–5% better than airport counters. Dozens of licensed changers compete along the main Myeongdong shopping street, and rates are posted on digital boards outside, so comparison shopping takes about two minutes of walking.
In Busan, head to the underground shopping arcade beneath Seomyeon station or the booths near Nampo-dong. Haeundae Beach also has several reputable changers, though rates there are slightly less competitive than central Busan.
For most currencies — US dollars, euros, Japanese yen, and Chinese yuan — you will get the best rates by exchanging cash at these street-level changers. Bringing crisp, undamaged USD 100 bills gets you the top rate; older series or damaged notes often fetch 1–2% less.
Airport vs. City: What the Numbers Look Like
Incheon Airport has licensed exchange counters from KEB Hana Bank and Woori Bank in the arrival halls. Rates are transparent, but you will typically get around 3–4% less than Myeongdong rates. On a USD 500 exchange, that is roughly ₩20,000–₩25,000 left on the table.
The practical strategy: exchange just enough at the airport for your first day — roughly ₩50,000–₩100,000 (about USD 38–76) — to cover transport and a meal. Do the bulk exchange once you reach the city.
- Airport rate example (June 2025): USD 1 ≈ ₩1,355 at Incheon counters
- Myeongdong street changer (same day): USD 1 ≈ ₩1,378
- Hotel exchange desk: USD 1 ≈ ₩1,320–₩1,335 (worst option, avoid)
Using ATMs Safely
Korea ATM network is extensive, but not all machines accept foreign cards — see our full guide to ATM withdrawals in Korea for machine-by-machine advice. The safest options are Global ATMs at GS25 and CU convenience stores, ATMs inside KEB Hana Bank or Woori Bank branches, and dedicated Global ATM machines at major subway stations. These carry the “Global ATM” sign and Visa/Mastercard logos.
Standard domestic ATMs — the beige or gray standalone machines — often reject foreign cards entirely. Skip them and find a convenience store instead.
- English menu available on most Global ATMs — tap the flag icon on the first screen
- Daily foreign-card withdrawal limit: typically ₩700,000–₩1,000,000 (≈ USD 530–760)
- Expect a USD 3–5 withdrawal fee plus 1–3% conversion fee from your home bank
- Notify your bank before arriving — Korean ATM transactions sometimes trigger fraud alerts
Cards with no foreign transaction fees — Charles Schwab debit, Wise, or Revolut — give you near-interbank rates and are worth having as a backup.
Scams and Pitfalls to Avoid
Korea is very safe for money exchanges. Licensed booth fraud is rare. The bigger risks are subtle:
- Unlicensed changers: Individuals (not booths) occasionally approach tourists near Gyeongbokgung or Dongdaemun with “special rates.” Always use a licensed booth — look for the posted registration number.
- Dynamic Currency Conversion (DCC): Card terminals sometimes ask if you want to pay in your home currency. Always select Korean Won (KRW) — DCC rates are consistently worse than your card rate.
- Miscounting notes: Korean bills come in ₩1,000, ₩5,000, ₩10,000, and ₩50,000. The ₩10,000 and ₩50,000 can look similar in dim light. Count your change before leaving the counter.
- Carrying too much cash: Korea is cashless-friendly — for a deeper look at when to use plastic versus won, see our guide to cards and cash in Korea. You rarely need more than ₩100,000–₩200,000 at any time. Most restaurants, cafes, and shops accept cards.
One final tip: pick up a T-money transit card at any GS25, CU, or 7-Eleven and load ₩30,000–₩50,000 on it. It covers subway, bus, and many convenience store purchases — reducing how much loose cash you need throughout the day.
ATMs, Banks, and Airport Counters: How They Compare
Beyond the Myeongdong money changers, travelers have several other options — each with different trade-offs on convenience versus rate. Understanding the differences upfront saves real money, especially on longer trips.
Airport counters (Incheon, Gimpo, Gimhae): Convenient on arrival but typically offer rates 4–7% worse than city changers. As of 2026 — verify before visiting — you can expect to receive roughly ₩1,320,000–₩1,340,000 per USD $1,000 at an airport counter versus ₩1,360,000–₩1,380,000 at a top Myeongdong booth. That gap adds up fast on larger exchanges. A practical workaround: exchange just enough at the airport for your first taxi or train fare (₩50,000–₩80,000 is usually sufficient), then change the rest in the city.
Korean banks (KEB Hana, Shinhan, Woori): Rates sit between airport counters and specialist money changers — usually 1–3% off the best street rates. Banks require your passport and can involve wait times of 20–30 minutes. Useful if you need a receipt for expense reporting or feel more comfortable in a formal setting.
ATMs with foreign cards: Global ATMs (marked in English, found in convenience stores like GS25 and CU, plus every subway station) let you withdraw won at your home bank’s exchange rate. Many travelers find this competitive, but watch for two fees: your home bank’s foreign transaction fee (typically 1–3%) and the Korean ATM operator fee (₩2,000–₩3,000 per withdrawal as of 2026 — verify before visiting). Withdraw larger amounts less frequently to minimise per-transaction charges.
Practical Tips to Avoid Common Mistakes
- Bring crisp, undamaged bills. Korean money changers routinely reject worn, torn, or heavily marked foreign notes — especially USD. Older series USD $100 bills (pre-2013) may also be declined at some booths.
- Avoid hotel exchanges entirely. Hotel desks routinely charge 8–12% above mid-market rate — the worst option outside of airport arrival halls.
- Check Naver Finance before you go. Search “USD KRW” on Naver to see the real mid-market rate, then benchmark any booth offering within 2% of that figure as a good deal.
- Keep your exchange receipts. You may need them when reconverting leftover won back to your home currency at departure — some counters require proof of original exchange.
- Small denominations matter. Request a mix of ₩10,000 and ₩50,000 notes. Smaller vendors and traditional markets (like Gwangjang or Jagalchi) rarely make change for large bills.
