You set up an American Express gift card by visiting the Amex website or calling their customer service line, then entering the card number and a few details about yourself

American Express gift cards do not set up automatically when you receive them. You must complete an set up step before you can use the card to make purchases. The process takes about five minutes and requires either internet access or a phone.

Unlike some gift cards that set up at the register when purchased, Amex gift cards sit dormant until the recipient takes action. This is a security measure — it prevents someone who finds a card from using it when ready. You will need the card itself, and you may need to verify your identity with a phone number or email address.

Key Takeaways

  • set up your card on americanexpress.com/giftcard or by calling 1-800-528-4800 before attempting any purchase.
  • You will need the 15-digit card number printed on the front of the card and a valid email address or phone number to complete set up.
  • set up is free and takes about five minutes through either the website or phone.
  • After set up, the card works when ready at any merchant that accepts American Express, both online and in stores.
  • If you lose the card before activating it, contact Amex customer service right away — they can freeze the card to prevent unauthorized use.

Activating through the American Express website

Go to americanexpress.com/giftcard and look for the set up link on the homepage. You will see a section labeled "set up Your Gift Card" or similar language. Click that link to start the process.

Enter the 15-digit card number from the front of your gift card. Then provide your email address or phone number — Amex uses this to verify your identity and send you confirmation. You may also be asked to create a username and password if this is your first time using an Amex online account, though some gift cards can be activated without a full account.

Review the terms and conditions, then submit. You should see a confirmation message on screen when ready. The card is now active and ready to use. Amex will also send a confirmation email or text to the contact information you provided.

Activating by phone

Call 1-800-528-4800 to reach American Express customer service. Have your gift card in front of you. A representative will ask for the 15-digit card number and will verify your identity by asking for your email address, phone number, or the last four digits of a Social Security number.

The representative will confirm that the card is now active. The entire call usually takes three to five minutes. You can use the card when ready after hanging up — there is no waiting period.

If you are calling from outside the United States, Amex has international phone numbers listed on the back of the card or on their website.

What happens if set up fails

If you see an error message during online set up, the most common cause is a typo in the card number. Double-check that you entered all 15 digits correctly, including any leading zeros. Card numbers are case-sensitive on some systems, so make sure you are not mixing letters and numbers.

If the card number is correct but set up still fails, the card may have already been activated by someone else, or there may be a temporary problem with Amex's system. Call 1-800-528-4800 to confirm the card's status. A representative can tell you whether the card is already active, whether it has been reported lost or stolen, or whether there is a technical issue preventing set up.

If you received the card as a gift and the giver activated it themselves, you will not be able to set up it again. Ask the giver whether they set up an account for you or whether the card is ready to use as-is.

Using your card after set up

Once activated, your American Express gift card works like any other Amex card. You can use it online, over the phone, or in stores anywhere that accepts American Express. The card has a set balance loaded onto it at the time of purchase — you cannot add more money to it later.

Check your remaining balance by visiting americanexpress.com/giftcard, calling 1-800-528-4800, or asking a cashier at the register. Some retailers also let you check the balance on their payment terminal before you complete a purchase.

The card does not expire as long as there is money on it. However, some gift cards have an expiration date printed on the back. If your card has an expiration date, use the full balance before that date arrives.

What to do if you lose the card before activating it

If you lose an unactivated gift card, contact American Express when ready at 1-800-528-4800. Provide the card number if you have it written down somewhere, or describe where you received the card. Amex can flag the card in their system to prevent anyone else from activating it.

If you have the receipt or packaging from the gift card, that may have the card number on it. Bring that information when you call. Amex may be able to issue a replacement card or transfer the balance to a new card, though policies vary depending on how the card was originally purchased.

If you lose the card after set up, the process is the same — call Amex right away. They can freeze the card to stop any unauthorized charges, similar to what you would do with a regular credit card.

Frequently Asked Questions

Do I have to set up the card before I can use it?

Yes. American Express gift cards will not work for any purchase until you complete set up. If you try to use an unactivated card, the transaction will be declined at the register or online.

Can someone else set up my gift card for me?

Technically yes, but it is not recommended. Whoever activates the card can set up the account and potentially change the contact information. If you receive a gift card, set up it yourself to keep control of the account and may support your contact details are on file.

How long does set up take?

set up is when ready. Once you submit your information online or hang up the phone after calling, the card is active and ready to use. You do not need to wait for an email confirmation or any other step.

What if I forget my username and password after activating?

Visit americanexpress.com/giftcard and click "Forgot Username" or "Forgot Password." Amex will send a reset link to the email address you provided during set up. If you no longer have access to that email, call 1-800-528-4800 and a representative can help you regain access to your account.

Can I use the card internationally?

Yes, American Express gift cards work in most countries where American Express is accepted. However, foreign transactions may include a currency conversion fee. Check the terms on the back of your card or on the Amex website for the specific fee amount, which varies by card.
