Where exactly you choose to exchange money in Seoul can add up to a genuinely noticeable difference in how much won ends up in your pocket for the same foreign bill — and the worst option, statistically, is also the most convenient and most commonly used one: the counter right in front of you at the airport.

Skip the airport counters
Incheon Airport's currency exchange counters sell convenience, not value — the rates posted here consistently run well below the genuine market rate, and they should really be treated as a last resort for just enough cash to cover your first taxi or a meal, not your main exchange of the trip.
Myeongdong's private exchange booths
A cluster of small, independently run currency exchange booths concentrated in Myeongdong consistently offers some of the best cash exchange rates available anywhere in the city — no commission charged, and rates are typically posted clearly on a digital board out front, so you can compare a few booths within a couple of minutes' walk before committing to one.
WOWPASS kiosks
As covered in more detail in our dedicated WOWPASS guide, these self-service kiosks combine a genuinely solid exchange rate with the convenience of loading that balance directly onto a card that also works for transit and everyday payments — a strong middle-ground choice if carrying loose cash around for the rest of the trip isn't appealing.

Bank counters
Major Korean bank branches — KEB Hana and Woori among the most visitor-friendly — will exchange foreign currency even for non-account-holders, typically at a rate better than the airport though with more paperwork involved and considerably shorter operating hours than a private booth.
What rate should you actually expect
Private Myeongdong booths typically land within a percent or two of the genuine interbank mid-market rate, banks land a bit further behind that, and airport counters trail noticeably further still — often several percent worse, which adds up meaningfully on a large exchange.
A simple rule of thumb
Exchange a small amount right at the airport, just enough to comfortably cover your first taxi ride or meal into the city, and hold off on your main currency exchange until you can reach a Myeongdong private booth or a WOWPASS kiosk once you're actually in Seoul.
Carrying large amounts of cash safely
Korea is generally very safe for carrying cash, but there's rarely a need to carry more than a day or two's worth at once — between widely accepted card payments and easy top-up access to WOWPASS kiosks, there's little reason to walk around with a large exchanged sum all at once.
Frequently asked questions
Should I exchange money before I leave home instead?
Rates at your home country's banks or airport counters are typically worse than what you'll find in Seoul — it's usually better to exchange only a small emergency amount before you fly and do the bulk of it in Myeongdong.
Do Myeongdong exchange booths take cards, or cash only?
Cash only, in the currency you're exchanging from — bring physical bills rather than expecting to swipe a card for the exchange itself.
Are there fake exchange booths or common scams to watch for?
Legitimate booths post their rates clearly and give a printed or verbal receipt — be cautious of anyone approaching you on the street offering to exchange money directly rather than at a fixed storefront location.
