Your account number appears in four places on an American Express card

The account number on an American Express card is the 15-digit number printed on the front of the card, usually below your name. This is the number you use to identify your account when you pay a bill, dispute a charge, or contact American Express customer service. It is not the same as your card number for online shopping — American Express uses a separate security code for that.

You can find your account number in the same locations every time: on the physical card itself, in your online account, in your monthly statement, and in any confirmation emails American Express sends you. Each location shows the same 15-digit number.

Key Takeaways

  • Your American Express account number is the 15-digit number printed on the front of your card, below your name.
  • The number also appears in your online account under Account Information or Account Details, accessible by logging into americanexpress.com.
  • Your monthly statement lists the account number at the top or in the account summary section.
  • If you cannot locate the number on your card or online, call American Express customer service at the number on the back of your card to confirm it.

On the front of your physical card

The account number is printed directly on the face of your American Express card in a single row of 15 digits. It sits below your name and above the expiration date. The digits are embossed (raised) so they can be read by older card readers, though most modern transactions do not require this.

If your card is damaged, faded, or lost, you will need to use one of the other methods below to locate the number. American Express can issue a replacement card with the same account number, though the card number itself (used for online purchases) will be different.

In your online American Express account

Log into your account at americanexpress.com using your username and password. Once you are logged in, look for a section labeled "Account Information," "Account Details," or "My Account." The account number is usually displayed at the top of this section or in a summary box.

If you have multiple American Express accounts, each one will have its own 15-digit account number. The online portal shows the account number for whichever account you are currently viewing. You can switch between accounts using a dropdown menu or account selector, usually near the top of the page.

On your monthly statement

Every monthly statement American Express sends you — whether by mail or email — lists your account number near the top. It usually appears in the upper left or right corner, sometimes labeled "Account Number" or "Account #." The statement also shows your billing period, payment due date, and current balance.

If you receive statements by email, the PDF attachment contains the same account number as a printed statement would. You can search your email inbox for "American Express statement" to find past statements if you need to reference the number again.

In confirmation and notification emails

When you open a new American Express account, the welcome email includes your account number. If you have set up account alerts or requested a statement by email, those messages also display the account number for reference. These emails are useful if you need the number quickly and do not have your card or statement nearby.

American Express also includes the account number in emails about account changes, such as address updates or credit limit increases. If you have deleted these emails, you can still retrieve the number from your online account or by calling customer service.

What to do if you cannot find the number

Call American Express customer service using the phone number printed on the back of your card. A representative can confirm your account number over the phone after verifying your identity. This usually takes less than five minutes and requires you to answer security questions or provide information from your account.

You can also visit an American Express office in person if one is located near you, though most people find it faster to call. Have your card or a recent statement ready when you contact them, as this speeds up the verification process.

Frequently Asked Questions

Is my account number the same as my card number?

No. Your account number is the 15-digit number on the front of your card. Your card number is different and is used for online purchases and payments. American Express treats these as separate identifiers for security reasons.

Can I use my account number to make a purchase online?

No. Online purchases require your card number, expiration date, and security code. Your account number is for billing inquiries, customer service calls, and account management — not for transactions.

What if my account number is different on my statement than on my card?

This should not happen. If the numbers do not match, contact American Express when ready. A mismatch could indicate an error in your account or a problem with how your statement was generated.

Do I need my account number to pay my bill online?

No. When you log into your American Express account online, the system already knows which account you are paying. You only need your account number if you are paying by phone or mail, or if you are setting up a payment from a different bank account.
