Discover works in most countries, but not everywhere, and you'll pay fees unless you plan ahead
Yes, you can use a Discover card internationally, but with real limits. Discover is accepted in roughly 190 countries, which sounds broad until you try to use it in a small town or at a local business. The card works at major chains, airports, and hotels worldwide. The problem is that Discover's network is much smaller than Visa or Mastercard — many smaller merchants, taxis, and regional banks straightforward don't take it.
Before you leave, contact Discover to let them know you're traveling. They don't always require this, but they monitor for fraud, and a sudden charge from another country can trigger a block. You can notify them through the mobile app, their website, or by calling the number on the back of your card.
Expect to pay fees. Discover charges a foreign transaction fee on every purchase made outside the United States — typically 1% of the transaction amount. Some premium Discover cards have no foreign transaction fee, but most standard cards do. ATM withdrawals abroad cost even more: a flat fee (usually $2 to $3) plus the 1% foreign transaction fee, plus whatever fee your bank charges for out-of-network withdrawals.
Key Takeaways
- Discover is accepted at major merchants and chains in most countries, but acceptance is thinner than Visa or Mastercard, especially outside cities and tourist areas.
- You will pay a 1% foreign transaction fee on purchases and withdrawals unless you hold a premium Discover card that waives this fee.
- Notifying Discover before you travel reduces the risk of your card being blocked for fraud, though it is not always required.
- Carrying a second card (Visa or Mastercard) as backup is practical because some merchants and ATMs straightforward do not accept Discover.
- The exchange rate Discover uses is set by Mastercard's network, not by Discover itself, so you cannot negotiate a better rate by calling customer service.
Where Discover is accepted and where it isn't
Discover acceptance varies sharply by country and by merchant type. In Western Europe, Canada, Australia, and Japan, you'll find Discover at most ATMs and major retailers. In the UK, Germany, France, and Spain, Discover works at supermarkets, gas stations, and hotels without much trouble. The real gaps appear in Southeast Asia, parts of Central America, and rural areas anywhere — a small restaurant in Thailand or a local shop in Peru may not take Discover at all.
The safest assumption is that Discover works at branded chains (McDonald's, Starbucks, major hotel groups), at airports, and at ATMs in city centers. For everything else — local restaurants, small shops, taxis, street vendors — cash or a Visa/Mastercard is more reliable. If you're traveling to a country where you're unsure, bring a backup card or plan to withdraw cash from ATMs in advance.
Foreign transaction fees and how they're calculated
Discover charges 1% of the transaction amount as a foreign transaction fee on every purchase outside the US. If you spend $100 at a store in London, you pay $1 in foreign transaction fees on top of the purchase. This fee is added to your statement in US dollars.
The exchange rate itself is set by Mastercard's network (Discover uses Mastercard's infrastructure internationally), not by Discover. You cannot call Discover and ask for a better rate — the rate is determined by the market at the time of the transaction. The 1% fee is separate from the exchange rate and is Discover's own charge.
ATM withdrawals are more expensive. You pay the 1% foreign transaction fee, a flat fee from Discover (usually $2 to $3 per withdrawal), and potentially another fee from the ATM operator or your bank. If you withdraw $200, you might pay $4 to $6 in fees total — roughly 2% to 3% of the amount withdrawn. This makes frequent small withdrawals costly; fewer, larger withdrawals are cheaper.
Premium Discover cards with no foreign transaction fees
Discover offers a few cards that waive the 1% foreign transaction fee. The Discover It Chrome and some business Discover cards have no foreign transaction fee, though these cards may have other costs or rewards structures. Check your specific card's terms or log into your Discover account to see whether your card waives this fee.
If you travel internationally often, switching to a card with no foreign transaction fee can save hundreds of dollars per year. However, you still face the acceptance problem — Discover is straightforward not taken everywhere, regardless of which Discover card you carry.
Notifying Discover before you travel
Discover monitors accounts for unusual activity. A sudden charge from a foreign country can trigger a fraud hold, which blocks your card until you confirm the transaction. Notifying Discover in advance reduces this risk.
You can set a travel notice through the Discover mobile app (under Account Services or Settings), through their website, or by calling the customer service number on the back of your card. Tell them the countries you're visiting and the dates you'll be there. This takes five minutes and can save you the frustration of having your card declined at a crucial moment.
What to do if your Discover card is declined
If a merchant says they don't take Discover, you have a few options. Ask if they take American Express — Discover and Amex have a partnership in some regions, and the merchant may be able to process it through that network. If not, ask for the nearest ATM and withdraw cash, or use a backup card if you have one.
Some merchants, particularly in Asia and Eastern Europe, may not recognize Discover at all. In these cases, cash is your only option. Plan your trip with this in mind: research whether your destination has reliable ATM access, and carry enough cash to cover a day or two of expenses if ATMs are scarce.
Comparing Discover to Visa and Mastercard abroad
Visa and Mastercard are accepted almost everywhere Discover is, and in many places where Discover isn't. If you're traveling to a less touristy area or a developing country, a Visa or Mastercard is significantly more useful. Many travelers carry both a Discover card and a Visa or Mastercard for this reason.
American Express has similar acceptance issues to Discover — it works well in developed countries and at major merchants, but is less reliable in smaller towns or developing regions. If you're choosing between cards for international travel, Visa and Mastercard are the safest bets, with Discover and Amex as useful backups in developed countries.
Currency conversion and how Discover handles it
When you make a purchase in a foreign currency, Discover converts it to US dollars using the exchange rate set by Mastercard's network at the time of the transaction. You don't choose the rate — it's determined by the market. The 1% foreign transaction fee is added on top of this converted amount.
You cannot lock in an exchange rate in advance or negotiate a better one by calling Discover. The rate you get is the rate that applies on the day of the transaction. This is the same process used by Visa, Mastercard, and most other card networks.
Frequently Asked Questions
Will my Discover card work at ATMs outside the US?
Yes, Discover works at most ATMs in developed countries and major cities worldwide. In rural areas or developing regions, ATM access may be limited. Withdraw cash in advance if you're unsure, and expect to pay $2 to $3 per withdrawal plus the 1% foreign transaction fee.
What happens if I use my Discover card and it gets declined?
Ask the merchant if they accept American Express (Discover and Amex partner in some regions). If not, find an ATM and withdraw cash, or use a backup card. Decline doesn't mean fraud — it usually means the merchant's system doesn't support Discover's network.
Can I avoid the 1% foreign transaction fee?
Only if you hold a Discover card that waives it, such as the Discover It Chrome. Check your card's terms or log into your account to confirm. Most standard Discover cards charge 1% on all foreign transactions.
Should I exchange money before I travel or use my Discover card?
Using your Discover card at ATMs usually gives you a better exchange rate than exchanging cash at an airport or bank. However, you pay ATM fees ($2 to $3 plus 1%), so withdraw larger amounts less often. For small purchases, using the card directly avoids the ATM fee.
Is Discover accepted in Europe?
Yes, Discover works at most major retailers, hotels, and ATMs in Western Europe. Acceptance is thinner in smaller towns and at local businesses. Bring a Visa or Mastercard as backup, especially if you're traveling outside major cities.
