Essential Guide to Currency Exchange in Korea: Best Spots, ATM Insights, and Avoiding Hidden Fees

The Complete Guide to Currency Exchange for Your Korea Trip — Where, How Much, and How to Avoid Losses

When planning a trip to Korea, currency exchange is often overlooked. Many travelers either exchange all their money at the first airport kiosk they see or arrive unprepared and panic without cash. With a little knowledge, you can avoid unnecessary losses. This guide covers everything you need to know about spending money efficiently in Korea.

1. Korea is a Card-Friendly Society — How Much Cash Do You Really Need?

Before diving into exchange methods, it's important to note that Korea is one of the most card-friendly countries in the world. You can use Visa, Mastercard, Amex, and other foreign cards at convenience stores, cafes, restaurants, taxis, subways, department stores, and supermarkets. So, there's no need to exchange a large amount of cash.

However, cash is still necessary in certain situations.

Situations Where Cash is Essential

Some stalls in traditional markets like Gwangjang Market, Namdaemun Market, Tongin Market
Small local eateries or street food stalls
Certain jjimjilbangs and saunas
Coin karaoke rooms and arcades
Paying cash for buses (though a T-Money card can solve this)
Small shops in rural towns

How Much Cash Should You Prepare?

Based on typical travel patterns:

City-focused trip in Seoul (7 days): ₩100,000–200,000 should suffice
If visiting traditional markets or traveling to rural areas: ₩300,000–400,000
If planning to use cards for most payments: ₩50,000–100,000 (for transport/emergencies)

In conclusion, you don't need to exchange a lot. If you run short, you can always withdraw more from an ATM.

2. Comparing Exchange Locations — Where's the Best Place to Exchange Money?

There are five main places to exchange currency. Here's an honest comparison of their features, pros, and cons.

① Incheon Airport Exchange Counters

Check the official Incheon Airport website for the location of exchange counters in each terminal.

Features: Available immediately upon arrival. Open 24 hours or from 7 AM to 9 PM.

Exchange Rates: The worst. Airports have a monopoly and thus offer poor rates, often worse than local banks.

Recommended Use: Only for small amounts to cover transport to the city. ₩20,000–30,000 should be enough.

Conclusion: ❌ Not recommended for major exchanges. Use only for emergencies.

② Myeongdong Private Exchange Booths

Features: Dozens of private exchange booths are clustered near Myeongdong Station. Known for the best rates in Seoul and possibly all of Korea.

Why Are Rates Better?: The competition among many booths on the same street drives fees down and offers rates close to the market rate. You can get 1–3% better rates than at banks.

Are Private Booths Legal?: Many travelers mistakenly think they are illegal, but they are legitimate businesses with proper registration. Feel free to use them.

Tips for Use

Bring your passport. ID verification is required for larger amounts.
Large denomination bills (e.g., USD 100) may get slightly better rates than smaller ones.
Count your money immediately after exchange to avoid disputes later.
Check real-time rates on the 'mibank' app or website before entering to save time.
Exit Myeongdong Station Exit 4 and walk towards the Chinese Embassy to find the booths.

Operating Hours: Most are open from 9 AM to 9 PM, with many open year-round.

Conclusion: ✅ Highly recommended for major exchanges. The larger the amount, the better the deal.

③ Euljiro Exchange Booths

Less known than Myeongdong, but there are good exchange booths near Euljiro 1-ga Station. They are less crowded and sometimes offer even better rates. Search 'Euljiro exchange' on Naver Maps to find them.

Conclusion: ✅ A good alternative to Myeongdong.

④ Seoul Station Exchange Counters

There are exchange counters at Seoul Station, the terminus of the Airport Railroad (AREX). If going to Myeongdong is inconvenient, you can exchange money here on your way from the airport. Rates are slightly worse than Myeongdong but much better than the airport.

Conclusion: 🟡 A second-best option if visiting Myeongdong is not feasible.

⑤ Local Banks

Exchange services are available at KEB Hana Bank, Woori Bank, Shinhan Bank, and KB Kookmin Bank. With exchange rate discount coupons, you can get 50–90% off fees.

How to Get Exchange Rate Discounts

Apply for exchange via the bank's mobile app and pick up at a branch
Use benefits for regular or VIP customers
Use exchange coupons offered by bank apps during travel seasons

Even with maximum discounts, rates are generally less favorable than Myeongdong. Choose this option if you prefer convenience or can't get to Myeongdong.

Conclusion: 🟡 Convenient but less favorable rates compared to Myeongdong.

Summary of Exchange Rate Comparison by Location

Incheon Airport Exchange: Least favorable — only for emergencies
Hotel Exchange: Can be worse than the airport — not recommended
Local Bank (without discounts): Unfavorable
Local Bank (with discount coupons): Average
Seoul Station Exchange: Average to good
Myeongdong/Euljiro Private Booths: Most favorable ✅

3. The Smartest Exchange Strategy

Based on the above, the most sensible exchange strategy is as follows.

Step-by-Step Recommended Strategy

Upon arrival at the airport: Exchange a small amount for city transport (₩20,000–30,000)
After entering Seoul: Conduct major exchanges at Myeongdong or Euljiro booths
If short: Withdraw additional cash from bank or convenience store ATMs using foreign cards

How Much to Exchange at Once?

It's sometimes better to split your exchanges. Since exchange rates fluctuate daily, exchanging half of what you need first and the rest as needed can reduce the risk of rate changes.

4. ATMs — What to Do If You Run Out of Cash

If you didn't exchange enough or spent more cash than expected, you can withdraw Korean won from ATMs using foreign cards.

ATMs That Work Well with Foreign Cards in Korea

Woori Bank ATMs: Foreigner-friendly, clean English interface
Shinhan Bank ATMs: Many locations nationwide, stable foreign card recognition
KB Kookmin Bank ATMs: Widely available at airports and major tourist spots
GS25 Convenience Store ATMs: Operate 'Global ATMs' supporting cards from over 40 countries
Citibank ATMs: Excellent global card network integration

Most ATMs with Visa, Mastercard, or Amex logos accept foreign cards. Fintech cards like Wise, Revolut, and N26 also work as they use Visa or Mastercard networks.

Fees Incurred When Using ATMs

Withdrawing cash with a foreign card at ATMs incurs two types of fees.

Local ATM Fee

Bank ATMs: ₩2,000–3,000 per transaction
Convenience Store ATMs: ₩2,500–4,000 per transaction

Home Country Card Issuer Fee

Regular credit/debit cards: Additional 1.5–3% of the withdrawal amount
Fintech cards like Wise, Revolut: Free or very low fees up to a monthly limit
Charles Schwab (USA): Full refund of overseas ATM fees
Starling Bank (UK): Free overseas ATM fees

Tips to Reduce Fees

Withdraw the needed amount in one go instead of multiple small transactions. Fees are charged per transaction.
Prepare a fee-free fintech card like Wise or Revolut before departure to significantly reduce ATM fees.
Inform your card issuer of your travel plans to prevent overseas transaction blocks.
Ensure you know your PIN before using ATMs. Resolving PIN issues locally can be very difficult.

How to Use ATMs

Facing a Korean ATM for the first time can be daunting. Follow these steps:

Insert card and select 'English' on the language screen
Select 'Withdrawal' or 'Cash Advance'
Enter your PIN
Enter the withdrawal amount (in ₩10,000 units)
Retrieve your card, cash, and receipt

Most bank ATMs operate 24/7, but some may have a maintenance period around midnight (10–20 minutes).

5. Card Payments — Tips to Save Money

Always Decline DCC (Dynamic Currency Conversion)

When using a foreign card in Korea, you might be asked, "Would you like to pay in Korean won or your home currency?" This is DCC (Dynamic Currency Conversion).

Always choose to pay in Korean won. Do not opt for your home currency.

Here's why: Paying in your home currency applies an exchange rate set by the merchant or payment processor, often with an additional 3–8% fee. Paying in won uses the official Visa or Mastercard rate, which is much more favorable.

When the option appears on the terminal, always select 'KRW'.

Before your trip, request a 'DCC block service' from your card issuer's app or customer service to prevent this option from appearing.

Structure of Overseas Transaction Fees

Using a foreign card in Korea incurs the following fees:

International brand fee (Visa/Mastercard): About 1% of the transaction amount
Card issuer's overseas service fee: Varies by card (usually 0–1.5%)

Totaling 1–2.5%, these fees may not be noticeable for small amounts but can add up over a long trip or large expenses.

Cards with No or Low Overseas Transaction Fees

Wise Debit Card: Minimizes exchange fees, no overseas transaction fees
Revolut Standard: Uses interbank rates on weekdays, free up to a monthly limit
Charles Schwab (USA): No overseas transaction fees, full refund of ATM fees
Starling Bank (UK): No overseas transaction or ATM fees

Obtaining such cards before your trip can greatly reduce fee burdens.

6. The Smartest Way to Spend Money in Korea

Depending on your travel style and duration, the most sensible combination for most travelers is as follows.

Recommended Combo A — Short Trip (3–5 days), Mainly Seoul

Small exchange at the airport (₩30,000 for transport)
Main exchange at Myeongdong booths for ₩100,000–150,000
Use a fee-free card for the rest of your payments

Recommended Combo B — Longer Trip (7+ days), Including Rural Areas

Small exchange at the airport (₩30,000)
Main exchange at Myeongdong booths for ₩200,000–300,000
Supplement with ATM withdrawals (prepare a fintech card)
Use cards for most payments

Recommended Combo C — Shopping at Traditional Markets, High Cash Usage

Exchange ₩400,000–500,000 at Myeongdong booths
Use ATM withdrawals as a backup

7. Things to Watch Out for When Exchanging Money

Beware of Counterfeit Bills

Counterfeit Korean won is rare but not impossible. When exchanging large amounts, always check the bills immediately. Legitimate private booths in busy areas rarely have counterfeit issues.

Conversely, avoid anyone offering to exchange money on the street in tourist areas. These are often scams or illegal exchanges.

Request Smaller Denomination Bills

If you receive only ₩50,000 bills, it can be hard to get change at small shops. Ask for a mix of ₩10,000 and ₩50,000 bills when exchanging. Most booths will accommodate this request.

Check Your Card's Overseas Payment Limit

If you're planning a long trip or expensive shopping, check and increase your card's overseas payment limit via the app or customer service before departure. This prevents payment rejections due to limit exceedance.

Carry a Backup Card

Prepare at least two cards in case of loss or theft. Keep one in your wallet and the other in your bag. Save your card issuer's overseas loss report number in advance.

8. What to Do with Leftover Won?

There are several ways to handle leftover won at the end of your trip.

① Re-exchange at the Airport Before Departure

There are exchange counters in the departure area of Incheon Airport. Although less unfavorable than upon arrival, rates are still worse than Myeongdong. For small amounts, re-exchanging at the airport is an option.

② Save for Your Next Korea Trip

If you plan to visit Korea again, keeping your won is the least costly option. The won is relatively stable and can be used next time.

③ Spend at Convenience Stores or Duty-Free Shops

Use leftover won to buy snacks or souvenirs at airport duty-free shops, convenience stores, or vending machines. Spending in ₩10,000 units at the airport can help you avoid exchange losses.

④ Dispose of Coins Before Returning

Korean coins (₩10, ₩50, ₩100, ₩500) are nearly impossible to re-exchange after returning home. Use them at convenience stores or vending machines before departure, or donate to airport charity boxes.

9. Frequently Asked Questions (FAQ)

Q. Is it better to bring USD or EUR?

A. US dollars (USD) are the most widely accepted and offer good rates. If traveling from Europe, euros (EUR) are also accepted at most booths with decent rates. It's inefficient to exchange to yen or other currencies first.

Q. Should I withdraw cash from an ATM or use an exchange counter upon arrival at the airport?

A. For small amounts, ATM withdrawals are fine. However, avoid multiple small transactions due to fees. For larger amounts, Myeongdong booths offer better rates.

Q. What exchange rate is applied when using a credit card in Korea?

A. The official rate set by Visa or Mastercard is applied. However, each card issuer may add an overseas transaction fee (0–1.5%). Declining DCC and paying in won ensures this official rate is used.

Q. Are there no fees when using Wise or Revolut cards in Korea?

A. Wise typically has very low or no fees for most transactions. Revolut Standard applies interbank rates on weekdays but adds a 0.5–1% markup on weekends. Both cards are usable at Korean ATMs, with ATM fees waived up to a monthly limit.

Q. Can I pay with Bitcoin or cryptocurrencies in Korea?

A. Some merchants accept it, but it's still very limited. Cash or card payments are much more convenient for general travelers.

Q. Are Myeongdong exchange booths trustworthy?

A. They are legitimate businesses with proper registration. Just make sure to check your money immediately after receiving it, as disputes are hard to resolve once you leave the booth.

10. Final Checklist Before Exchanging Money

Check these items before and after arriving in Korea.

Before Departure

Apply for Wise, Revolut, or a fee-free overseas card (recommended 1–2 weeks before departure)
Inform your card issuer of your travel plans (to prevent transaction blocks)
Check and increase your card's overseas payment limit if necessary
Save your card issuer's overseas loss report number
Apply for DCC block service
Keep a backup card separately

After Arrival at the Airport

Exchange a small amount at the airport for transport (₩20,000–30,000)
Conduct main exchanges at Myeongdong or Euljiro booths after reaching the city
Consider ATM fees and withdraw the needed amount in one go

There's no "one-size-fits-all" solution for currency exchange. The best method depends on your travel duration, budget, and style. However, one thing is clear — avoid exchanging everything at the airport, use Myeongdong booths, and carry a fee-free card to minimize unnecessary expenses. Knowing saves money, while ignorance leads to losses in currency exchange.
