The credit card number is on the front of your card, usually in a raised or printed row of 16 digits

Your credit card number is the 16-digit code printed or embossed on the front of your card, typically in the center or lower half. This number identifies your specific account with the card issuer — it is not the same as your account number with your bank, and it is not the same as your PIN.

The number appears in one of two ways: raised digits you can feel when you run your finger across them, or flat printed digits. Either way, it is the most visible number on the card's front side. If you have multiple cards from the same issuer, each one has a different credit card number.

Key Takeaways

  • Your 16-digit credit card number is printed or embossed on the front of the card, usually in the center area.
  • The three-digit security code (CVV or CVC) is on the back of the card, to the right of the signature strip.
  • The expiration date appears on the front as two numbers separated by a slash, showing the month and year the card expires.
  • Never share your full credit card number, expiration date, or security code with anyone unless you initiated a purchase or payment.
  • The cardholder name on the front should match the name on your ID when you use the card in person.

What the 16 digits represent

The 16-digit number breaks down into sections that identify your card issuer, your account, and a check digit. The first digit or first few digits identify the card network — Visa cards start with 4, Mastercard with 5, American Express with 3, and Discover with 6. The next digits identify your specific bank or card issuer, and the remaining digits identify your individual account.

You need this full number to make online purchases, phone orders, or mail orders. When you swipe or insert your card in person at a store, the merchant's machine reads the number from the card's magnetic stripe or chip, so you do not have to recite it. The last digit is a check digit that helps detect typos or fraud — if someone enters the number incorrectly, that digit will not match.

Where to find the expiration date

The expiration date sits on the front of the card, usually to the right of the credit card number or below it. It appears as two numbers separated by a slash — for example, 08/26 means the card expires in August 2026. The first number is the month, the second is the year.

Your card stops working after the last day of the expiration month. If your card expires on 08/26, you can use it through August 31, 2026, but not on September 1, 2026. Your card issuer will mail you a replacement card before the expiration date, usually 30 to 60 days in advance. You should update any recurring payments (subscriptions, automatic bills) with the new card number and expiration date before the old card expires.

Finding the security code on the back

The security code — also called CVV (Card Verification Value) or CVC (Card Verification Code) — is a three-digit number on the back of your card. It sits to the right of the signature strip, either printed on the card itself or embossed. This code is not printed on your receipt and does not appear on your statement, which is why merchants ask for it during online or phone purchases — it proves you have the physical card in your hand.

American Express cards have the security code on the front, above the card number, and it is four digits instead of three. If you have an Amex card, look for a four-digit code in the upper right corner of the front.

Why merchants ask for different pieces of information

When you shop online, a merchant typically asks for the card number, expiration date, and security code. They do not ask for your PIN because your PIN is for ATM withdrawals and debit card transactions at stores, not credit card purchases. If a merchant asks for your PIN during a credit card transaction, that is a sign of fraud — do not provide it.

In person at a store, you insert or swipe the card and may be asked to sign or enter a PIN depending on the transaction amount and the merchant's system. You do not need to recite your card number because the machine reads it from the card itself. If a store employee asks you to read your card number aloud, that is unusual and a reason to be cautious.

How to protect your card number and other details

Never share your full credit card number, expiration date, or security code with anyone unless you initiated the transaction. Legitimate merchants and your card issuer will never ask you to provide these details via email, text, or phone call. If someone contacts you claiming to be from your bank or a store and asks for this information, hang up or delete the message and call the number on the back of your card instead.

When you shop online, look for a padlock icon in the address bar and a URL that starts with "https" — the "s" means the connection is encrypted. Cover the card with your hand or position it so others cannot see the number when you are in public. If you lose your card or suspect fraud, call the number on the back of your card when ready — most issuers can freeze the card within minutes.

What information appears on your statement instead

Your monthly statement shows the last four digits of your card number, not the full 16 digits. This is a security measure — it lets you confirm which card was used for a transaction without exposing the entire number. Your statement also shows the merchant name, the transaction date, and the amount charged, but it does not show your security code or PIN.

If you see a transaction you did not make, contact your card issuer right away. Most cards offer fraud protection, meaning you are not responsible for unauthorized charges if you report them promptly. Keep your statements and check them regularly — catching fraud early makes the dispute process faster.

Frequently Asked Questions

Is my credit card number the same as my account number?

No. Your credit card number is printed on the card itself and identifies that specific card. Your account number is an internal identifier your bank uses and may be different. Your statement shows the last four digits of your card number, not your full account number.

Can I use my card if the number is partially worn off?

If the number is unreadable, you cannot use the card online or over the phone because merchants will not be able to process it. In person, the card's chip or magnetic stripe may still work even if the printed number is faded. Contact your card issuer to request a replacement card if the number is no longer legible.

What should I do if someone asks for my card number in person?

In a store, you should never need to recite your card number — the merchant's machine reads it from the card. If a cashier or employee asks you to read it aloud, that is unusual. Politely decline and ask to insert or swipe the card yourself, or use a different payment method.

Do I need to memorize my credit card number?

You do not need to memorize it. Most people keep their card with them or store the number securely in a password manager or encrypted app. Memorizing it is optional and not necessary for everyday use.

Why is my new card number different from my old one?

Each physical card has its own unique 16-digit number. When your card expires or is replaced due to damage or fraud, the issuer assigns a new number to the new card. This is normal and does not affect your account — it is the same account with a new card.
