Yes, you can use your credit card abroad, but it will cost you money and carry real risks you need to understand before you leave
Your credit card will work in most countries — the Visa and Mastercard networks operate in nearly every nation. But using it abroad triggers fees your card issuer charges, currency conversion costs that are often hidden, and fraud risk that is higher than at home. You will pay more per transaction than you would at home, sometimes significantly more. The question is not whether you can use it, but whether you should, and how to do it safely if you do.
Before you travel, contact your card issuer and tell them where you are going and when. Many cards now have fraud detection that flags international purchases as suspicious — if your card gets declined in a restaurant in Barcelona because the system thinks it is stolen, you will not have an straightforward time getting it reversed on the spot. A quick call to the customer service number on the back of your card, or through your online account, takes five minutes and prevents that problem.
Key Takeaways
- Your card issuer charges a foreign transaction fee — usually 1 to 3 percent of the purchase amount — every time you use your card outside the United States.
- The exchange rate your card uses is set by the card network, not by you, and is often worse than the real market rate on the day of the transaction.
- Notifying your card issuer before travel prevents fraud blocks that can leave you without access to money when you need it most.
- ATM withdrawals abroad often cost more than card purchases because both your bank and the foreign bank charge fees, but they may be your safest option in some countries.
- A second card from a different issuer, kept separate from your main card, protects you if one card is lost or stolen during travel.
Foreign transaction fees and how they add up
Every time you swipe your card outside the United States, your card issuer charges you a foreign transaction fee. This fee is a percentage of the purchase amount, usually between 1 and 3 percent, though some cards charge as much as 5 percent. A $100 dinner in Paris costs you $101 to $105 depending on your card. Over a two-week trip with daily purchases, these fees add up to real money.
Some cards — particularly travel rewards cards and premium cards with annual fees — waive foreign transaction fees entirely. If you travel regularly, switching to one of these cards before your trip can save you hundreds of dollars. Check your card's terms by logging into your online account or calling the number on the back of your card. The terms document will list the foreign transaction fee under "Fees" or "International Transactions."
Budget airlines, hotels, and tour operators often charge in their local currency and add their own conversion fees on top of what your card charges. When you book online, you may see a price in dollars, but the company converts it to the local currency, charges you, and your card converts it back — you pay fees twice. Read the fine print before you book to see what currency you are actually being charged in.
Currency conversion and exchange rates you do not control
When you use your card abroad, the purchase happens in the local currency — euros, pounds, pesos, whatever. Your card network (Visa, Mastercard, American Express) converts that amount to dollars using an exchange rate they set. This rate is almost never the real market rate you would see if you exchanged money at a bank or currency exchange. The difference — called the markup — is how the card network makes money on international transactions.
You cannot negotiate this rate or shop around for a better one. The rate is locked in the moment the transaction clears, which may be days after you made the purchase. If the dollar weakens against the euro between the day you bought something and the day the charge posts to your account, you pay more. You have no control over any of this, and your card issuer will not tell you the markup in advance.
The only way to know what you actually paid is to compare the exchange rate on your statement to the real market rate on the day of the transaction. Use XE.com or OANDA to look up the historical rate. If the difference is more than 2 percent, your card network's markup was steep. This is normal — it does not mean you were cheated — but it is worth knowing so you can factor it into your budget.
Fraud risk and how to protect yourself
Credit card fraud happens more often abroad than at home because card security standards vary by country. In the United States, most merchants use chip readers that are harder to clone. In many other countries, magnetic stripe readers are still common, and your card data is easier to steal. Skimming devices — hidden readers that capture your card number when you swipe — are more prevalent in some tourist areas.
You cannot eliminate this risk, but you can reduce it. Never let your card out of your sight — do not hand it to a waiter who disappears into a back room to process it. If that is the only option, go with them or pay at the register instead. Use ATMs in banks or inside stores rather than standalone machines on the street. Check your statement weekly while you are away, not after you return home. If you see a charge you did not make, contact your card issuer when ready — the sooner you report it, the faster they can reverse it and send you a replacement card.
Bring a second card from a different bank, kept in a separate location from your main card. If your primary card is lost, stolen, or compromised, you still have access to money while you wait for a replacement. Many travelers keep one card in their wallet and another in their hotel safe or with a travel companion.
ATM withdrawals versus card purchases abroad
Using an ATM to withdraw cash in the local currency is often cheaper than you think, even though both your bank and the foreign bank charge fees. Your bank charges an ATM fee — usually $2 to $5 per withdrawal — and the foreign bank may charge another $1 to $3. But you avoid the foreign transaction fee that you would pay if you used your card to buy something. If you are making large purchases, the math often favors the ATM.
The exchange rate at an ATM is usually better than the rate your card network uses for purchases, because ATMs are connected directly to the banking system. You will still pay the markup, but it is typically smaller. Withdraw cash in larger amounts less often — one $200 withdrawal costs less in fees than four $50 withdrawals — but never carry more cash than you would feel comfortable losing.
In countries where card fraud is common or where card readers are unreliable, cash is often safer than plastic. Ask other travelers or check recent travel forums for the country you are visiting. If people report frequent card problems, plan to use ATMs and carry cash instead of relying on your card.
What to do if your card is lost or stolen abroad
Call your card issuer when ready — do not wait until you get home. The phone number is on the back of your card, but if you do not have your card, you can find it on your online account or on your billing statement. Many card issuers have 24-hour international customer service lines. Tell them your card is lost or stolen, and they will cancel it and begin the fraud investigation process.
Ask whether they can send a replacement card to your hotel or to an address in the country you are visiting. Some issuers can do this; others cannot. If they cannot, ask how long it will take for a replacement to reach you at home and whether they can issue a temporary card number you can use online. In the meantime, use your backup card or withdraw cash from an ATM.
Report the loss to local police if you believe the card was stolen rather than lost. You may need a police report for your card issuer's fraud investigation, and you may need it for your travel insurance claim if you have one.
Notifying your card issuer before you travel
Call your card issuer or use your online account to tell them the countries you will visit and the dates you will be there. This prevents your card from being blocked as fraudulent when you make your first purchase abroad. The system flags international transactions as suspicious by default — it is designed to protect you, but it can also leave you stranded without access to money.
You do not need to ask permission or get approval. You are straightforward informing them so their fraud detection system knows to expect charges from those locations. This takes five minutes and can save you hours of frustration trying to reach customer service from a foreign country.
If you are traveling to a remote area or a country where your card issuer does not normally see transactions, mention that specifically. Some issuers will make a note on your account that you are traveling there, which gives their fraud team a heads-up if something unusual happens.
Frequently Asked Questions
Will my credit card work everywhere I travel?
Visa and Mastercard work in most countries, but not everywhere. Small towns, rural areas, and some developing countries may have few card readers. Ask your hotel or tour operator in advance what payment methods they accept. Bring some cash as backup, and research ATM availability before you arrive.
Is it cheaper to exchange money before I leave or use my card abroad?
Using your card is usually cheaper than exchanging money at an airport or currency exchange, even with the foreign transaction fee and markup. Airport exchanges charge 5 to 10 percent markups. Your card's markup is typically 1 to 3 percent plus the foreign transaction fee. ATM withdrawals are often the cheapest option overall.
What should I do if a charge appears on my statement that I did not make?
Contact your card issuer as soon as you notice it — do not wait. You are protected by federal law against unauthorized charges, and the sooner you report it, the faster they can investigate and reverse it. Provide the date, amount, and merchant name. Your issuer will open a dispute and send you a replacement card.
Can I use my credit card to get cash from an ATM abroad?
Yes, but it costs more than using a debit card. Credit card ATM withdrawals are treated as cash advances, which means your issuer charges a cash advance fee (usually 3 to 5 percent) plus interest that starts accruing when ready. Use a debit card for ATM withdrawals if you have one. If you must use a credit card, withdraw larger amounts less often to minimize fees.
What if my card issuer will not send a replacement card while I am traveling?
Use your backup card, withdraw cash from an ATM, or ask your hotel to help you contact your card issuer to arrange a temporary solution. Some issuers can issue a temporary card number for online purchases. If you are stranded without access to money, contact your bank's international customer service line — they have options for emergencies that are not available through the standard phone line.
