When you receive a new American Express card in the mail, activation is a straightforward but essential step before you can use it. Understanding your activation options—and what happens during the process—helps you start using your card safely and on your own timeline.
Activation confirms your identity and signals to American Express that you've received your card. Until activated, your card typically cannot be used for purchases, even if you've been approved for the account. This protection prevents unauthorized use if your card is lost or intercepted in transit.
Some American Express cards may allow limited use before activation (such as adding the card to a digital wallet), but activation is required for full functionality at most merchants.
Call the number printed on the back of your card or on the welcome materials included with it. You'll reach American Express customer service, which will ask you to verify your identity using information from your application. This typically takes a few minutes and is available 24/7.
Log into your American Express account at americanexpress.com or through the mobile app, then follow the prompts to activate your card. This method is quick—often completed in under a minute—and is available anytime.
If you've already downloaded the American Express app, you can activate directly through it when your card is added to your profile.
Certain American Express products allow activation at a retail location or partner establishment, though this is less common than the digital and phone options above.

You may also be asked to confirm your contact information, set up online account access, or review account features and terms. The entire process is secure—American Express won't ask for your full card number during activation, only verification details tied to your application.
Activate as soon as it's convenient for you. You don't need to activate immediately upon receiving the card, but waiting offers no benefit. Delaying activation simply delays when you can use your card.
If you activate by phone, customer service can sometimes answer questions about your card's features, rewards structure, or account benefits in the same call.
If activation fails, check that:
If you encounter repeated issues, call the number on the back of your card or your welcome materials. Customer service can troubleshoot the problem or activate your card manually.
Once activated, your card is ready to use at any merchant that accepts American Express. You can use it for in-store purchases, online transactions, or add it to digital payment systems like Apple Pay or Google Pay (which may have their own activation steps).
The right activation method depends on your preferences: phone activation works well if you have questions; online or app activation is fastest if you just want to get started. Either way, the process is designed to be straightforward and take only a few minutes of your time.
