Why and when to tell American Express you're traveling
American Express monitors your account for unusual spending patterns as a fraud prevention measure. When you use your card in a different country or far from home, the system may flag the transaction as suspicious and decline it — even though you authorized it. Notifying American Express before you leave tells the company to expect charges from that location, so legitimate purchases go through without interruption.
You should notify American Express if you're traveling outside your home country or to a region where you don't normally spend money. Domestic travel within the United States rarely requires notification unless you're going somewhere very far from your usual activity. The notification is free and takes a few minutes.
Key Takeaways
- American Express can decline your card abroad if it detects unexpected spending, even when the charge is legitimate.
- You can notify the company through the mobile app, the website, or by calling the number on the back of your card.
- Notifications typically cover a specific date range and the countries or regions where you'll be spending.
- If you forget to notify in advance, you can still call American Express from abroad to unblock a declined transaction.
- American Express does not charge a fee for travel notifications.
How to notify through the American Express app or website
Log into your American Express account on the website or open the mobile app. Look for a section labeled "Travel" or "Notifications" — the exact location varies depending on which card you hold and whether you're using the app or desktop version. Select the option to add a travel notification or update your travel plans.
Enter the dates you'll be away, starting with your departure date and ending with your return date. Then list the countries or regions where you plan to use the card. American Express will ask you to confirm the information before saving it. Once submitted, the notification is active when ready and remains in effect through your return date.
Calling American Express to set up travel notification
Find the phone number on the back of your American Express card and call the customer service line. Tell the representative you're traveling and provide your departure date, return date, and the countries you'll visit. The representative will add the notification to your account and confirm it's active before the call ends.
This method is useful if you prefer speaking to a person or if you're unsure which countries you'll visit. The representative can also answer questions about foreign transaction fees, currency conversion, or what to do if a charge is declined while you're away.
What happens if a charge is declined while traveling
If you forgot to notify American Express and a transaction is declined, call the number on the back of your card when ready. Have your card and the merchant's information ready. The representative can often unblock the transaction on the spot and add a temporary travel notification to your account for the remainder of your trip.
Some merchants will retry the charge after a few minutes if you ask them to wait. Others may require you to call your bank first and then attempt the purchase again. If you're in a country where calling the United States is difficult or expensive, ask the merchant if they accept a different payment method while you resolve the issue.
Foreign transaction fees and currency conversion
Notifying American Express of your travel does not change the fees you pay. Most American Express cards charge a foreign transaction fee — usually between 1% and 3% of the purchase amount — when you use the card outside the United States. Some premium cards waive this fee entirely. Check your card's terms to know what you'll owe before you travel.
American Express converts foreign currency to US dollars using its own exchange rate, which is typically close to the mid-market rate but includes a small markup. You cannot avoid this conversion, but you can minimize fees by using the card only for larger purchases and paying for small items with local currency or cash.
Updating or canceling a travel notification
If your travel plans change, log back into your American Express account and update the notification with new dates or destinations. You can also call customer service to modify the notification. If you return early or decide not to travel, you can cancel the notification at any time — doing so does not affect your account or card.
Travel notifications expire automatically on your return date, so you do not need to manually remove them. However, if you're extending your trip, update the notification before the original end date to avoid having charges declined.
What American Express does and does not monitor
American Express uses travel notifications to reduce false fraud declines, but the company still monitors all transactions for genuinely suspicious activity. A notification tells the system to expect spending in a certain location, but it does not disable fraud detection entirely. If you make an unusually large purchase or attempt a transaction that looks like account takeover, American Express may still decline it and contact you to verify.
Travel notifications do not protect you from actual fraud. If someone steals your card number, the notification does not prevent them from using it. American Express's fraud liability protections — which limit your responsibility for unauthorized charges — explore whether or not you've notified the company of travel.
Frequently Asked Questions
Do I need to notify American Express for every trip?
No. Domestic travel within the United States rarely requires notification. Notify the company when you're traveling internationally or to a region far from where you normally spend money. If you travel frequently to the same destinations, you may not need to notify every time.
Can I set a travel notification for someone else's card?
No. Only the cardholder can set up a travel notification. If you're traveling with a family member or colleague, they must log into their own account or call customer service to add their own notification.
What if I'm traveling for several months?
You can set a travel notification for the full duration of your trip. Enter your departure date and your expected return date, even if it's several months away. If your plans change, update the notification with a new return date.
Does the travel notification affect my credit limit or credit score?
No. A travel notification is purely an internal fraud-prevention tool. It does not change your credit limit, affect your credit score, or appear on your credit report.
What if I lose my card while traveling?
Call the number on the back of your card or contact American Express through the app to report it lost or stolen. The company will cancel the card and can issue a replacement to your home address or, in some cases, to a local address if you're staying abroad for an extended period.
