Tell American Express before you travel so your card doesn't get blocked

American Express monitors your card for unusual activity. If you use your card in a different country or state without warning them first, they may decline transactions as a fraud prevention measure. Notifying American Express of your travel plans takes a few minutes and prevents your card from being frozen while you're away from home.

You can send a travel notice through the American Express website, mobile app, or by phone. The process is the same whether you're traveling domestically or internationally. American Express typically accepts travel notices up to 30 days before your trip, though you can also notify them while traveling if plans change.

Key Takeaways

  • You can notify American Express of travel through their website, mobile app, or by calling the number on the back of your card.
  • Travel notices prevent your card from being declined due to fraud alerts when you use it in unfamiliar locations.
  • American Express accepts travel notices up to 30 days in advance and removes them automatically when your trip ends.
  • If you forget to notify them and your card is declined, call the number on the back of your card to verify the transaction and unblock it temporarily.

Notify through the American Express website or app

Log into your American Express account on their website or open the American Express mobile app. Look for a section labeled "Travel" or "Travel Notifications" — this is usually found under account settings or in the main menu.

Enter the dates you'll be traveling and the countries or states where you plan to use your card. You can add multiple destinations if your trip involves several locations. American Express will confirm your travel notice when ready and show you the dates it covers.

The travel notice stays active until the end date you set. You don't need to remove it manually — it expires automatically. If your plans change and you need to extend your trip, you can update the dates in the same section.

Notify American Express by phone

Call the customer service number on the back of your American Express card. Have your card and travel dates ready when you call. Tell the representative where you're traveling and when you'll be gone.

The representative will add the travel notice to your account and confirm the dates it covers. This method works if you prefer speaking to someone directly or if you're having trouble finding the travel notification feature online. The phone line is available 24 hours a day.

What happens if your card is declined while traveling

If you forgot to notify American Express and your card is declined, call the number on the back of your card when ready. Have your card and a form of identification ready. The representative can verify the transaction on the spot and temporarily unblock your card so you can complete the purchase.

After you verify the transaction, the representative may ask if you want to add a travel notice for the rest of your trip. This prevents future declines for the same reason. Once you're home, the temporary unblock expires and your account returns to normal monitoring.

Travel notices for supplementary cardholders

If you have supplementary cardholders on your account, you need to notify American Express for each card that will be used during the trip. You can add travel notices for all supplementary cards in the same process — either through the website, app, or by phone.

When you call, tell the representative which cards need travel notices. If you're using the website or app, you may see an option to select multiple cards. Make sure every card that will be used internationally or in an unfamiliar location has its own notice.

Traveling with multiple American Express cards

If you have more than one American Express card, you need to set a travel notice on each one separately. Log into each account or call and request a travel notice for each card. This ensures none of your cards will be blocked due to unusual activity.

You can set different travel dates for each card if you're using them for different trips. For example, if you're taking one card on a business trip and another on a vacation, each can have its own travel notice with different dates.

How long travel notices last and what to do when you return

Travel notices expire automatically on the end date you provide. You don't need to call or log in to remove them. After the notice expires, American Express returns to normal fraud monitoring for your account.

If your trip is extended and you need to keep the notice active longer, log back into your account or call customer service to update the end date. It's easier to extend before the original date expires, but you can also add a new notice if needed.

Frequently Asked Questions

Can I set a travel notice for a trip that starts tomorrow?

Yes. American Express accepts travel notices at any time, including the day your trip begins. You don't have to plan 30 days ahead — that's just the maximum advance notice they allow. If you're leaving tomorrow, you can add the notice right now.

What if I'm traveling to multiple countries?

List all the countries where you'll use your card when you set up the travel notice. You only need one notice that covers your entire trip, not separate notices for each country. Just make sure the dates span your entire time away.

Does a travel notice prevent fraud, or just stop false declines?

A travel notice tells American Express to expect activity in certain locations, so they won't block legitimate transactions. It doesn't prevent actual fraud — American Express still monitors for suspicious activity even with a notice active. If someone uses your card without permission, you're still protected by their fraud liability policy.

Can I remove a travel notice before my trip ends?

Yes. Log into your account or call customer service to delete the notice early. This is useful if your trip is cut short or if you decide not to travel. Once removed, American Express returns to normal fraud monitoring when ready.

What if I'm traveling but didn't set a notice — can I still use my card?

You can try, but your card may be declined if American Express flags the transaction as unusual. If it is declined, call the number on the back of your card to verify the purchase. The representative can unblock it temporarily, but it's faster and easier to set a travel notice before you leave.
