Discover works in most countries, but not everywhere, and you'll pay foreign transaction fees unless you have specific card versions

Discover is accepted in roughly 190 countries and territories worldwide, but acceptance is thinner outside North America than Visa or Mastercard. You can use your Discover card at merchants and ATMs in most major cities and tourist areas, but you may hit dead zones in smaller towns or rural regions where only local cards or Visa work. Before you travel, contact Discover to let them know your destination and dates — they can flag your account so they don't block legitimate foreign purchases as fraud.

Every Discover purchase outside the United States triggers a foreign transaction fee of 1% of the purchase amount. This fee appears on your statement as a separate line item. ATM withdrawals abroad cost 1% plus whatever fee the ATM operator charges (often $2 to $5 USD equivalent). The Discover It card and most other Discover products charge the same rate, so there is no way to avoid this fee by switching between Discover cards.

Key Takeaways

  • Discover is accepted in roughly 190 countries, but acceptance is less reliable than Visa or Mastercard in smaller towns and rural areas.
  • Every foreign purchase costs 1% of the amount as a foreign transaction fee, charged by Discover in addition to the purchase price.
  • ATM withdrawals abroad cost 1% plus the ATM operator's fee, which typically runs $2 to $5 per withdrawal.
  • Notifying Discover of your travel dates before you leave prevents your card from being blocked as a fraud precaution.
  • Discover cards cannot be used in countries under U.S. sanctions, including Iran, Syria, North Korea, and Cuba.

Where Discover is accepted and where it isn't

Discover acceptance is strongest in developed countries with established payment networks. You will have no trouble using Discover in Canada, the United Kingdom, Australia, Japan, South Korea, and most of Western Europe. Major cities in Mexico, Brazil, and other Latin American countries accept Discover at hotels, restaurants, and retail chains, though smaller merchants may not.

Acceptance drops sharply in parts of Asia, Africa, and the Middle East outside major tourist corridors. Rural areas anywhere tend to be cash-only or local-card-only. Some countries, including China and India, have payment networks that strongly favor domestic cards, so Discover may work at international hotel chains but not at local shops. Before traveling to a country you have not visited before, search online for "Discover card accepted in [country]" or contact Discover directly to ask about specific cities or regions.

Discover cannot be used in countries under U.S. economic sanctions. This includes Iran, Syria, North Korea, and Cuba. If you are traveling to any of these destinations, Discover will decline your card even if the merchant accepts it.

How foreign transaction fees work

When you swipe or insert your Discover card abroad, the merchant's bank converts the local currency to U.S. dollars using the Visa or Mastercard exchange rate for that day (Discover uses their network's rate). Discover then adds 1% of the converted amount as a foreign transaction fee. This fee is separate from the exchange rate markup — you pay both.

Example: You buy something for 100 euros in France. The exchange rate that day is 1 euro = $1.10 USD. The purchase converts to $110. Discover charges you $110 plus $1.10 (the 1% fee), for a total of $111.10 on your statement. The fee appears as a line item labeled "foreign transaction fee" or similar language.

Some credit cards from other issuers waive foreign transaction fees, but Discover does not offer this on any of its consumer cards. If you travel internationally often, you may want to carry a second card from an issuer that does not charge this fee, though those cards typically have annual fees or other trade-offs.

Using ATMs to withdraw cash abroad

You can withdraw U.S. dollars or local currency from ATMs that display the Discover logo. Discover charges 1% of the amount withdrawn, plus whatever fee the ATM operator charges. ATM operator fees vary widely — some charge $2, others charge $5 or more. You will see both fees on your statement: the Discover fee and the operator fee listed separately.

Withdrawing larger amounts at once costs less per dollar than making multiple small withdrawals, since you pay the operator fee only once. However, carrying large amounts of cash abroad carries its own risks. A reasonable approach is to withdraw $200 to $300 at a time if the ATM fee is $3 or less, and to use your card for most purchases instead.

Some ATMs abroad do not accept Discover. If an ATM declines your card, try a different machine or a different bank's ATM. ATMs at airports and in city centers are more likely to accept Discover than ATMs in remote areas.

Notifying Discover before you travel

Contact Discover before you leave the United States and tell them the countries you will visit and the dates you will be there. You can do this through the Discover mobile app, by calling the number on the back of your card, or through your online account. Discover uses this information to avoid blocking your card when they see charges from unfamiliar locations.

If you do not notify Discover and they see a charge from abroad, they may decline the transaction or freeze your account as a fraud precaution. This can leave you without access to your card in a foreign country, and it can take hours or days to resolve by phone. The notification takes five minutes and prevents this problem entirely.

Currency conversion and exchange rates

Discover does not set the exchange rate. When you make a purchase in a foreign currency, the merchant's bank converts it to U.S. dollars using the Visa or Mastercard exchange rate for that day. Discover then applies their 1% foreign transaction fee to the converted amount. The exchange rate you see on your statement may differ slightly from the rate you see online, because exchange rates change throughout the day and the conversion happens at the moment the transaction is processed, not when you swipe the card.

You cannot lock in an exchange rate in advance with a credit card. If you want to minimize exchange rate risk on a large purchase, you can withdraw cash in advance from your bank at their exchange rate, but this requires planning and carries the risk of carrying large amounts of cash.

What to do if your card is declined abroad

If a merchant declines your Discover card, the most common reasons are that Discover is not accepted in that location, the merchant's payment terminal is not working, or Discover has blocked the transaction as a fraud precaution. Ask the merchant if they accept Discover — some accept Visa and Mastercard but not Discover. If they do accept Discover, ask them to try the transaction again.

If the card is declined a second time, call Discover using the number on the back of your card. You may need to use an international calling plan or a calling app like Skype to reach them. Have your card number and the merchant's name ready. Discover can tell you whether the decline was a fraud block or a network issue, and they can unblock your card if needed. If you cannot reach Discover by phone, use your online account or the mobile app to send a message — response times vary, but Discover typically replies within a few hours.

Frequently Asked Questions

Do I need a special Discover card to use it internationally?

No. All Discover cards work internationally. There is no separate international version. Every Discover card charges the same 1% foreign transaction fee abroad, so switching cards will not save you money on fees.

Can I use Discover at restaurants and shops in Europe?

Yes, in major cities and tourist areas. Acceptance is reliable in London, Paris, Barcelona, Rome, and other large cities. Smaller towns and rural areas may be cash-only or accept only local cards. Always carry some euros or pounds in cash as a backup.

What happens if I use Discover in a country where it is not accepted?

The merchant's terminal will decline your card. You will not be charged. Ask if they accept other payment methods, or find a different merchant that accepts Discover or another card you carry.

Is the 1% foreign transaction fee charged on top of the exchange rate?

Yes. Discover converts your purchase to U.S. dollars at the day's exchange rate, then adds 1% of that converted amount as a separate fee. You pay both the exchange rate and the fee.

Can I use Discover to pay bills or make online purchases from abroad?

Yes. Online purchases and bill payments made from abroad are treated the same as purchases made in the United States — no foreign transaction fee applies. The fee only applies to in-person purchases and ATM withdrawals in foreign countries.
