For Korea money exchange, start with a bank or authorized exchange service center. Bring your passport, compare how many Korean won you will actually receive, and arrange cash for your arrival before chasing a better rate elsewhere. If a card terminal offers to charge you in your home currency, pause: that is a separate conversion decision.

This guide is based on official tourism, Seoul city and Visa guidance. We have not exchanged cash or tested a Korean ATM for this article.

Quick answer: make an arrival plan first

Korea’s currency is the won, usually shown as KRW or the symbol ₩. The Korea Tourism Organization’s currency guide recommends banks and authorized exchange service centers.

Choose your starting point by what you need next:

Key takeaways

  • You need won before leaving the airport: look for an airport exchange counter and confirm that it is open and accessible from your arrival area.
  • You already have arrival cash: compare an authorized exchange office or bank near your planned route. Ask for the final won payout, not just the advertised rate.
  • You plan to rely on a card: check your issuer’s overseas fees and cash-withdrawal conditions before flying, and keep a backup way to pay.
  • You land late: identify an open counter in your terminal before departure. Do not assume that every airport bank branch stays open overnight.

There is no “best exchange shop” ranking here. We have not collected same-time quotes from competing counters, so we cannot name today’s cheapest location.

Airport exchange: convenient, but check the exact counter

The tourism organization’s exchange FAQ calls airport exchange service centers the easiest option for most tourists. Its airport banking guide lists bank branches and exchange counters at Incheon.

An airport bank branch and an exchange counter can have different hours. That guide describes standard exchange-counter hours as 06:00–22:00, with some locations potentially operating 24 hours; it also lists ordinary bank-branch hours separately. The page was last updated September 11, 2026, so treat it as a starting point rather than a promise about your arrival.

Before you fly:

  1. Check your arrival terminal.
  2. Open Incheon Airport’s facilities directory and find the banking or currency-exchange listings for that terminal.
  3. Check the individual counter’s hours and whether it is in a public area or an area requiring a boarding pass.
  4. If the location or overnight hours are unclear, confirm with the bank or airport rather than depending on an old screenshot.

If you want to exchange only enough for the first part of your trip, decide that amount from your own arrival plan. There is no universal cash allowance that suits a train transfer, a prepaid airport bus and a late taxi equally well.

For the transport decision, see our Incheon Airport to Seoul guide. Keep the fare plan separate from the exchange quote so you know what you need before leaving the terminal.

Banks and city exchange offices

VISITKOREA says banks are generally open 09:00–16:00 on weekdays, with hours varying by bank and region. Check the individual branch before making a special trip.

For an exchange office, confirm that it is an authorized service and that it accepts the currency and notes you are bringing. VISITKOREA warns that some locations may not accept old currency.

Take that warning literally if you have older banknotes left from another trip. Ask about the exact series or condition before traveling across the city with them; do not assume that “US dollars accepted” answers every question about your notes.

If you are considering an exchange office in Myeongdong, compare its final payout rather than assuming a location guarantees savings. Treat any “best rate” recommendation as a lead to compare, not a guaranteed saving. Check the final payout and weigh any difference against the extra trip you would need to make.

Avoid building your day around a small headline rate difference before you know the actual amount saved. It is reasonable to choose a convenient authorized counter when the alternative would disrupt your plans.

Bring your passport and confirm the payout

Seoul Metropolitan Government’s exchange guidance says you must present a passport or residence card when exchanging currency. For a visitor traveling with a passport, bring it to the counter; do not rely on a phone photo as your only identification.

Use this sequence before handing over cash:

  1. Name your currency and amount. Say, for example, “I want to change 100 US dollars into Korean won.”
  2. Ask for the final payout. “How many won will I receive after any fees?”
  3. Check the direction. Confirm that the quote is for the counter buying your foreign cash and giving you won, not the reverse transaction.
  4. Ask about your notes. Confirm acceptance before agreeing, particularly for older notes.
  5. Check the transaction before leaving. Count the won, check any receipt, and ask about a discrepancy while you are still at the counter.

These are comparison steps, not a claim that every counter uses the same rate board, fee structure or receipt format.

For a large cash transaction, get the bank’s requirements and the relevant customs guidance directly before traveling. This guide does not set out cash declaration thresholds or large-amount exchange rules.

Compare the won you receive, not the headline

Ask two providers the same question about the same amount and currency. A “no commission” sign alone does not tell you which quote leaves you with more won.

Here is an illustrative example, not a current exchange rate:

  • Counter A quotes ₩135,000 after all fees for your cash.
  • Counter B quotes ₩136,000 after all fees for exactly the same cash.
  • Counter B gives you ₩1,000 more in this example.

Now decide whether collecting that difference is worth the extra journey. Do not compare one provider’s final payout with another provider’s headline rate before fees.

If an online currency converter is part of your planning, do not treat its number as the amount a counter has agreed to pay. Ask for the actual transaction quote.

You also do not need to exchange your entire trip budget in one go just because you have found a counter. Consider how much cash you want to carry and where you could obtain more if your plans change.

Card payments and ATMs: watch the conversion choice

VISITKOREA says major credit cards can be used in Korea, while advising travelers to check availability before a purchase because some stores may not offer the service. Do not turn “widely accepted” into a guarantee for every purchase.

Before travel, ask your card issuer about overseas purchase fees, cash-withdrawal fees, withdrawal limits and whether your intended card is suitable for ATM use. This guide has not verified compatibility or fees for your particular card and a Korean ATM.

Also check any fee shown by the ATM before confirming. If you plan to withdraw with a credit card, ask your issuer whether cash-advance fees or interest apply.

There is another choice to recognize: dynamic currency conversion (DCC). Visa explains that a merchant or ATM may offer to convert a transaction into your home currency.

For Visa transactions, its guidance says the screen and receipt should show the local and home-currency amounts, the exchange rate and any additional fee or markup. You should have the choice to accept or decline conversion; the provider should not choose for you.

Visa’s travel advice is to decline that conversion and pay in local currency to avoid the DCC markup. In Korea, the local-currency choice is KRW.

Declining DCC is not the same as canceling the purchase or withdrawal: Visa says accepting or declining it does not affect your ability to transact internationally. It also does not establish that your transaction is fee-free; check your issuer’s terms separately.

If the screen is unclear, stop before confirming and ask for help or cancel. Do not agree to a home-currency amount merely because it looks familiar.

If your first cash plan fails

The counter is closed: check another official listing in the same terminal or area. Confirm access and opening hours before walking to it.

Your notes are refused: ask which notes or currencies the provider accepts, then compare another authorized provider. Do not count on every office accepting the same notes.

A card or ATM transaction is declined: read the message, check your issuer’s app or contact the issuer, and use your backup payment plan. We have not tested a universal fix for Korean ATM declines.

The exchange quote is unclear: ask for one final won amount for your exact cash. If you cannot establish what you will receive, do not proceed.

Before-you-fly checklist

  • Bring your passport and confirm any unusual banknote acceptance.
  • Identify an arrival exchange option in your terminal, with current hours.
  • Plan enough accessible money for the journey to your accommodation.
  • Check your card issuer’s overseas purchase and withdrawal terms.
  • Compare final won payouts for the same amount and currency.
  • Recognize the KRW versus home-currency conversion choice.
  • Keep a backup payment option separate from your main card.

FAQ

Do I need a passport to exchange money in Korea?

Seoul’s official guidance requires a passport or residence card. Bring your passport rather than relying on a photo.

Should I exchange money at Incheon Airport or in Seoul?

Choose the airport if you need won before continuing your journey. If your arrival needs are covered, compare a convenient authorized city provider’s final payout. We have not established that either location is always cheaper.

Are airport exchange counters open 24 hours?

Some are, according to official tourism and Seoul city guidance. Not every counter or bank branch is. Check the exact terminal, location and current hours before relying on one.

Should I choose KRW or my home currency on a card terminal?

Visa advises choosing local currency to avoid the DCC markup. In Korea that means KRW; check your card issuer’s own fees as a separate question.
