Currency Exchange Guide for Seoul: Best Rates & Local Bureaus
BLUF: Avoid converting large sums at Incheon International Airport (ICN), where retail currency desk spreads range from 4% to 9%. For the absolute best South Korean Won (KRW) cash exchange rates in Seoul, head directly to the famous cluster of licensed private money changers in Myeongdong near the Chinese Embassy (such as Daesagwan and Ilpumhyang), which offer the tightest cash margins in the country between 0.25% and 0.6% on USD, JPY, EUR, and TWD with zero added commissions.
Seoul is one of the world's most technologically advanced cashless societies, where credit cards are accepted practically everywhere. However, physical cash is mandatory for topping up Tmoney transit cards at subway machines, buying street food in Myeongdong, and shopping at traditional markets like Gwangjang and Namdaemun.
