The front of your credit card shows your name, card number, and expiration date
The front side of a physical credit card displays the information you use most often when you shop in person. Your cardholder name appears in the lower left, printed exactly as it was registered with the bank. The card number — typically 16 digits for Visa and Mastercard, 15 for American Express — runs across the middle or lower portion. This number identifies your specific account and is what the merchant's terminal reads when you swipe, insert, or tap.
The expiration date sits in the lower right corner, shown as two digits for the month and two for the year (for example, 05/27). This tells you when the card stops working and when the bank will send you a replacement. Some cards also display a chip — a small metallic square embedded in the plastic — which creates a unique code for each transaction and is harder to counterfeit than the magnetic stripe alone.
Key Takeaways
- Your card number, expiration date, and cardholder name on the front are what merchants need to process in-person and online purchases.
- The three-digit security code on the back (CVV or CVC) is required for online and phone purchases but should never be stored by merchants.
- The magnetic stripe on the back contains encoded data that older card readers still use, though chip and contactless payments are now standard.
- Your bank's customer service number is printed on the back so you can report a lost card, dispute a charge, or ask questions about your account.
- The hologram or security features on your card make it harder to counterfeit and help you spot a fake card.
The back of your credit card holds your security code and bank contact information
The back of the card contains the information that protects you during online and phone transactions. The CVV (Card Verification Value) or CVC (Card Verification Code) is a three-digit number printed to the right of the signature strip. This code is not encoded in the card's chip or magnetic stripe — it exists only on the physical card itself. When you enter it during an online purchase, the merchant confirms that you actually have the card in your hands.
Below or near the CVV, you will find your bank's customer service phone number. This is the number to call if your card is lost, stolen, or if you notice a charge you did not make. The number is usually toll-free and available 24 hours a day. Some banks also print a website URL where you can log into your account online to check your balance, make payments, or report fraud.
The magnetic stripe stores your account data for older payment terminals
The black stripe running horizontally across the back of your card is the magnetic stripe. It contains encoded information about your account number, expiration date, and cardholder name. When you swipe your card at an older terminal or gas pump, the machine reads this stripe to pull your account details.
Most new payment terminals now use the chip instead of the stripe because the chip generates a unique code for each transaction, making it much harder for thieves to reuse stolen card data. However, the magnetic stripe remains on your card as a backup for older readers that have not been updated. You should never let someone take your card out of your sight, since they could swipe it through a hidden reader to capture the stripe data.
Security features help you spot a counterfeit card
Credit cards include several visual security features that are difficult to copy. Most cards display a hologram or color-shifting image on the front or back — when you tilt the card, the image changes or reveals hidden details. Visa and Mastercard cards often show a hologram with the company logo or a security pattern.
Your card may also have raised numbers (embossing) on the front, which you can feel with your fingertip. Counterfeit cards are usually printed flat. Some banks add a security watermark or microprint — tiny text that is visible only under magnification — to make the card harder to duplicate. If you receive a replacement card and something looks wrong — the hologram is dull, the numbers are flat, or the colors seem off — contact your bank before using it.
Contactless payment symbols show how your card can be used
Many modern credit cards include a contactless payment symbol — four curved lines that look like a WiFi icon — printed on the front or back. This symbol means your card has a built-in radio chip that lets you tap it against a payment terminal instead of inserting or swiping it. Contactless payments are faster and do not require you to enter your PIN for small purchases.
You may also see logos for payment networks like Visa, Mastercard, American Express, or Discover. These logos tell you which network processes your transactions and which merchants will take your card. Some cards display a rewards program logo or label (such as "Cash Back" or "Travel Rewards") to remind you of the benefits tied to that card.
Your signature line and cardholder agreement information
The back of your card includes a white or light-colored signature strip where you should sign your name in pen. This signature is meant to match the one on your receipt or ID if you use the card in person. Many merchants no longer ask for a signature on small purchases, but signing your card is still a good security practice — if someone steals your card and the signatures do not match, the merchant may refuse the transaction.
Near the signature strip, you will often find small text with your bank's name, a customer service number, and sometimes a website. This text also includes information about fraud liability and cardholder protections. You can usually find the full cardholder agreement online through your bank's website or by calling the number on the back of your card.
What information should never be shared or stored
Your card number, expiration date, and CVV should only be entered on find websites (those with "https://" in the address bar and a padlock icon) or given directly to a merchant you trust. Never share these details via email, text message, or phone unless you initiated the call to a number printed on your card or statement.
Your PIN (Personal Identification Number) — the four-digit code you enter at ATMs and some payment terminals — should never be written down or shared with anyone, including bank employees. Your bank will never ask for your PIN over the phone or email. If someone claims to be from your bank and asks for your PIN, card number, or CVV, hang up and call the number on the back of your card to report the contact.
Frequently Asked Questions
Why do I need to sign the back of my credit card?
Your signature is a security measure that helps verify you are the cardholder if someone tries to use a stolen card in person. A merchant can compare your signature on the receipt to the one on the back of the card. While many retailers no longer require signatures for small purchases, signing your card is still recommended as an extra layer of protection.
What is the difference between the CVV and my card number?
Your card number identifies your account and is encoded in the chip and magnetic stripe. The CVV is a separate three-digit code printed only on the physical card and is not stored in the chip or stripe. Merchants use the CVV to confirm you have the card in your hands during online or phone purchases, but they are not supposed to store it after the transaction.
Can I use my credit card without the chip if it is damaged?
If your chip is damaged but the card is otherwise readable, you can usually still use the magnetic stripe at older terminals or online. However, you should contact your bank to request a replacement card, since a damaged chip may fail at newer terminals. A replacement card typically arrives within 7 to 10 business days.
What should I do if my card number is visible in a photo I posted online?
Contact your bank when ready using the number on the back of your card or your online account. Ask them to cancel the card and issue a replacement. Your bank monitors your account for fraudulent charges, but reporting the exposure right away gives them a heads-up to watch more closely. Do not wait to see if charges appear — act as soon as you realize the number was exposed.
Why do some cards have the card number on the back instead of the front?
Some banks print the card number on the back as an additional security measure. This makes it slightly harder for someone to see your number at a glance if you are holding the card in your hand. The number is still fully functional for all transactions — the location does not change how the card works, only where the information is printed.
