Foreign credit cards in Korea can work well for many purchases, but acceptance is not universal, and cash withdrawals depend on your card network, your issuer, and the ATM. This guide explains what to check before you travel so you are not caught without a way to pay or get Korean won.

1. Can You Use Foreign Credit Cards in Korea?
South Korea uses the Korean won (KRW). The Korea Tourism Organization’s VISITKOREA says most businesses in Korea widely accept credit cards, including at major hotels, department stores, and general shops, and it lists Visa, Mastercard, American Express, and others. It also advises checking that card service is available before you buy, because some stores may not offer it.
When you rely on foreign credit cards in Korea, keep a backup payment method with you, such as a second card or some Korean won. The sources reviewed do not recommend a specific amount of cash to carry. If you are buying concert tickets, see our guide on how foreign fans can buy K-Pop concert tickets in Korea.
2. How to Withdraw Korean Won with a Foreign Card
Cash access for foreign credit cards in Korea depends on the card and the machine. Work through these points in order:
- Ask your card issuer before you leave. Confirm that overseas use and ATM withdrawals are enabled on your card, and ask about the issuer’s own fees and limits.
- Use a compatible ATM. JCB states that cards issued outside Korea can only be used at Global ATMs. Its list of Korean partner institutions includes major banks such as KB Kookmin, Shinhan, Hana, and Woori, plus Hyosung TNS. The list is dated September 15, 2026, so check it again before you travel. This rule is specific to JCB. Do not assume it describes Visa, Mastercard, or other networks.
- Expect limits to vary. JCB says the ATM withdrawal limit may vary and that you may not be able to withdraw a large amount of cash in a single session.
- Read the screen carefully. The sources reviewed do not describe a standard ATM screen sequence or button labels, so follow the prompts on the machine you are using. Check any currency-conversion offer and fee details before you confirm (see the currency section below).
3. Foreign Credit Card vs. Debit Card: What to Check
A card that works for purchases is not guaranteed to work for cash. Purchase and withdrawal functions can be set up differently, and the sources reviewed do not establish a rule that a foreign credit card can withdraw cash at every Global ATM. Credit card cash advances, eligibility, and fees depend on the issuer and the card product, so your issuer is the party to ask.
| Topic | Card payments | ATM cash withdrawals |
|---|---|---|
| Where it works | Widely accepted, including at major hotels, department stores, and general shops, but some stores may not offer card service. | Compatible ATMs only, such as Global ATMs for overseas-issued JCB cards. Restrictions differ by card brand. |
| What to confirm first | Ask the business whether it takes cards before you order or buy. | Ask your issuer whether ATM withdrawals are enabled, and what its fees and limits are. |
Use this checklist before you travel:
| Check | What to confirm | Why it matters |
|---|---|---|
| Issuer permissions | Overseas use and ATM cash withdrawals are enabled on your card. | The issuer controls these settings, and the sources reviewed give no Korea-specific issuer instructions. |
| ATM compatibility | Which ATMs your card network says it supports in Korea. | Network rules differ. JCB’s published Global ATM guidance applies to JCB cards only. |
| Fees and limits | Fees and limits set by your issuer and by the ATM operator. | The sources reviewed give no single Korea-wide fee or limit, and the two parties may each have their own terms. |
| Backup payment | A second card, some Korean won, or both. | Not every business accepts cards, and a withdrawal can fail. |
4. Should You Choose Korean Won or Your Home Currency?
When you use foreign credit cards in Korea at a shop terminal or an ATM, you may be offered Dynamic Currency Conversion (DCC). With DCC, the merchant or ATM converts the transaction into your card’s home currency instead of charging it in Korean won.
Visa says it requires merchants and ATMs to show the amount in both currencies, the exchange rate used, and any additional fees or markup, and that you must be given a choice to accept or decline the conversion. JCB notes that at some ATMs you may be offered a currency other than the local one, and that in that case the rate is set by the ATM owner, not by JCB. DCC is not necessarily offered everywhere, and the sources reviewed do not show that either currency choice is always cheaper. Compare the figures on the screen before you confirm, and check your issuer’s terms for any charges it adds.
5. What to Do If Your Card Does Not Work
- At a shop: The business may simply not offer card service. Ask whether another payment method works, or use your backup.
- At an ATM with a JCB card: Try a Global ATM from JCB’s published partner guidance, since overseas-issued JCB cards are limited to those machines.
- Any declined payment or withdrawal: Contact your card issuer and confirm that overseas use and ATM withdrawals are enabled. The sources reviewed do not explain the causes of declines or give a Korea-wide troubleshooting procedure, so your issuer is the one who can tell you why a specific transaction failed.
- If you need cash without a compatible ATM: VISITKOREA says to visit a bank or an authorized exchange service center. Banks are generally open 09:00–16:00 on weekdays, but hours may vary by bank and region. The Seoul Metropolitan Government says you must present a passport or residence card when exchanging currency.

6. Can Short-Term Visitors Open a Korean Bank Account?
Don’t count on it. The Seoul Metropolitan Government’s banking page describes how a “resident foreigner,” defined as someone who has been in Korea for more than six months, can open an account by visiting a bank with a foreigner registration certificate and passport. It does not state account-opening requirements for visitors staying a shorter time, so do not assume a short-term tourist can open an account on the same terms.
