When you hold an American Express card, you're looking at one of the most recognizable card designs in the world. But if you're trying to find your card number—whether to make an online purchase, set up automatic payments, or verify your account—knowing exactly where to look matters.
The 15-digit card number on an American Express card is printed prominently on the front face, usually in the center-right area of the card. This is the number you'll use most often for transactions.
The number appears in two formats:
Unlike many Visa or Mastercard designs, American Express places this number in a distinctive location that's become synonymous with the brand itself.
Beyond the card number, your American Express card contains several other pieces of identifying information:
The security code (CVV): This is a 3-digit number printed on the front of the card, usually on the right side near your name. This code is required for online and phone purchases and adds a layer of security by confirming you physically possess the card.
Expiration date: Located on the front, typically below or near the card number, showing the month and year your card is valid through.
Your cardholder name: Embossed on the front so merchants can verify the card matches the person using it.
Bank routing information and issuer details: Often printed on the back, though these are primarily for bank processing rather than everyday use.
Keeping your card number secure starts with understanding where it lives on your card. Since the front-facing number is visible to anyone handling the physical card, never photograph or screenshot your full card number and share it online. The expiration date and security code should be treated with the same caution.
When entering your card number for online purchases, you're typically typing it into a secure payment portal. The card itself stays in your wallet—you're simply reading the digits from your physical card.
If you use American Express's digital wallet or app, your card information may be stored differently than on the physical card. Many digital payment systems tokenize your card data, meaning merchants don't see your actual card number—they see a substitute token instead. This adds a security layer, though the underlying card number remains the same.
The location and visibility of your card number are only part of the security picture. Your responsibilities include:
The right practices depend on where and how you're using your card—online shopping, in-person transactions, phone orders, or account management all carry different considerations.
Your American Express card is designed for easy identification and use, but the visibility of your number on the front means personal responsibility for how you handle it matters more than ever.
