Your account number is on your physical card, your statement, and in the Amex app
Your American Express account number is a 15-digit code that identifies your specific card and account. You can find it in four places: printed on the front of your physical card, on any monthly statement Amex sends you, in the American Express mobile app or website, and in confirmation emails from Amex.
The fastest route is your physical card if you have it in front of you. If you don't have the card, your online account takes 30 seconds. If you've never set up online access, a paper statement or a call to Amex customer service will get you the number.
Key Takeaways
- Your 15-digit account number appears on the front of your physical American Express card, below your name.
- Log into your Amex account online or through the mobile app to see your account number under account details or card information.
- Any monthly statement Amex mails to you displays your account number at the top or in the account summary section.
- If you cannot locate it yourself, call American Express customer service at the number on the back of your card or a recent statement.
Finding it on your physical card
The account number is printed directly on the front of your American Express card. It's the 15-digit number that appears below your name and above the expiration date. The digits are embossed (raised) so they can be read by card readers and felt by touch.
This is the quickest method if your card is available. You don't need to log in, wait for mail, or call anyone. Simply look at the front of the card and write down or photograph the number.
Checking your online account or app
Go to americanexpress.com and sign in with your username and password. Once logged in, navigate to the account details or card information section—the exact label varies depending on your account type, but it's usually near the top of the dashboard or under a menu labeled "Account" or "Cards."
Your account number will be displayed there in full. You can also use the American Express mobile app: open it, sign in, and look for your card details or account summary. The app often shows the number prominently on the card preview screen.
If you don't have an online account yet, you can create one at americanexpress.com by clicking "Register" and following the prompts. You'll need your card number and other identifying information to set it up.
Looking at your monthly statement
American Express mails paper statements to the address on file for your account. Your account number appears near the top of the first page, usually in the account summary section or next to your name and address.
If you receive electronic statements instead, log into your online account and download or view your most recent statement as a PDF. The account number is in the same location as it would be on a paper statement.
What to do if you can't find it yourself
Call American Express customer service. The phone number is printed on the back of your physical card. If you don't have the card, the number is also on any recent statement Amex sent you.
When you call, have your name, address, and the last four digits of your card ready. The representative will verify your identity and provide your full account number. Wait times vary by time of day, but you should reach someone within 10 to 20 minutes during business hours.
Why you need your account number
Your account number is required for certain transactions and inquiries: paying your bill by phone or mail, disputing a charge, setting up automatic payments, or contacting Amex about your account. Some merchants also ask for it when processing refunds or handling returns.
Do not share your account number with anyone you don't trust. Treat it the same way you would your full card number. If you suspect fraud or unauthorized use, call Amex immediately using the number on your card or statement.
Frequently Asked Questions
Is my account number the same as my card number?
No. Your card number is the 15-digit number embossed on the front of your card. Your account number is also 15 digits and appears in the same location, but they refer to the same underlying account. For most purposes, Amex treats them interchangeably, but some transactions specifically ask for one or the other.
What if I have multiple American Express cards?
Each card has its own 15-digit number. If you have a personal card and a business card, or multiple personal cards, each one has a different account number. Log into your online account to see all your cards and their respective numbers listed separately.
Can I find my account number if my card is lost or stolen?
Yes. Log into your online account or call Amex customer service. You do not need the physical card to access your account number. If you've lost the card, report it to Amex at the same time so they can cancel it and issue a replacement.
Where is the account number on my statement?
It appears at the top of the first page, usually in the account summary box next to your name and mailing address. On some statements it may also appear in the top right corner. Check the header section of your statement first.
