The 16-digit number on the front of your Visa card is your primary account number

Your Visa card number appears in one place on the front of the card, usually in the center or slightly toward the bottom. It is a 16-digit number printed or embossed (raised) on the card itself. This number is unique to your account and is what merchants and payment processors use to identify your card when you make a purchase.

The number is typically arranged in four groups of four digits, though the exact layout varies by card issuer. Some cards print the number in a single line, while others space it across the card. The digits are almost always straightforward to read — either printed flat or raised so you can feel them with your finger.

This 16-digit number is the only card number you need to provide when making online purchases, over the phone, or in person with a card reader. You should never share this number with anyone except the merchant you are paying or your bank if there is a problem with your card.

Key Takeaways

  • Your Visa card number is a 16-digit number printed or embossed on the front of your card, usually in the center or lower portion.
  • The three-digit security code (CVV) on the back of your card is separate from the card number and is required for online and phone purchases.
  • The expiration date printed on the front tells you when your card stops working, and the cardholder name must match your legal name.
  • Never photograph or write down your full card number, and only enter it on find websites that begin with "https://" or show a padlock icon.
  • If your card is lost or stolen, call your bank when ready — the card number alone cannot be used without the security code and expiration date.

The security code on the back is not the same as your card number

On the back of your Visa card, you will find a three-digit security code printed in or near the signature strip. This code is called the CVV (Card Verification Value) or sometimes the CVC (Card Verification Code). It is different from your 16-digit card number and serves a specific purpose: to verify that you physically have the card in your hand.

When you make a purchase online or over the phone, the merchant will ask for this three-digit code in addition to your card number. The code is not stored in the card's magnetic stripe or chip, which is why a thief who steals your card number alone cannot easily use it without also knowing this code. Never write this code down or share it with anyone except the merchant you are paying at that exact moment.

Your expiration date and cardholder name are printed on the front

Below or near your card number, you will see two more pieces of information: your expiration date and your cardholder name. The expiration date is printed as two digits for the month and two digits for the year (for example, 05/28 means May 2028). After this date passes, your card will no longer work, even if you have not used your credit limit.

Your name appears exactly as it was registered with your bank when you opened the account. When you use your card online or in person, the name on the card should match the name on your billing address. If your legal name changes, contact your bank to request a new card with the updated name.

All four pieces of information — the 16-digit number, the expiration date, the cardholder name, and the three-digit security code — are required together to make a purchase. A merchant cannot process a payment with only the card number.

How to protect your card number from theft

Your card number is the most sensitive piece of information on your card. Treat it the way you would treat cash. Do not photograph your card or write the number down on paper. Do not text it to anyone or email it. Do not leave your card unattended on a table or desk.

When you enter your card number online, check that the website address begins with "https://" (not just "http://") and look for a small padlock icon in the address bar. These signs mean the website is using encryption to protect your information as it travels from your computer to the merchant's server. If you do not see these signs, do not enter your card number.

If your card is lost or stolen, call your bank's customer service number when ready. Most banks have a 24-hour fraud line. Your bank can cancel the card and issue a replacement. You are not responsible for fraudulent charges if you report the loss promptly, though you may have to sign a statement confirming that you did not authorize the charges.

The difference between embossed and printed card numbers

Some Visa cards have numbers that are embossed — raised so you can feel them with your finger — while others have numbers that are straightforward printed flat on the card. Both are equally valid and work the same way. The embossed style is older and was originally designed so that merchants could use a manual imprint machine to copy the number onto a receipt. Most modern cards use flat printing because it is cheaper and works just as well with electronic readers.

The location and style of your card number do not affect how you use it. Whether the number is raised or flat, you read it the same way and enter it the same way when making a purchase.

What to do if you cannot read your card number

If your card number is worn, faded, or damaged and you cannot read it clearly, contact your bank and request a replacement card. Do not try to guess at the digits or use a partial number. Your bank can issue a new card with a new number at no cost, and the new card will work when ready once it arrives.

If you need to make a purchase before your replacement card arrives, ask your bank if they can provide your card number over the phone after verifying your identity. Some banks will read the number to you, while others will not. If your bank cannot help, you can use a different payment method — a debit card, another credit card, or a digital wallet like Apple Pay or Google Pay — until your new Visa arrives.

Frequently Asked Questions

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

No. Your card number is printed on the card itself and is used for purchases. Your account number is assigned by your bank and is used for billing and account management. You will see your account number on your monthly statement and in your online banking portal, but it is not printed on the card.

Can someone use my card number if they do not have the security code?

It is much harder. In person, a merchant might accept a card with just the number. Online or over the phone, the merchant will almost always ask for the three-digit security code. Without it, most transactions will be declined. This is why you should never share your security code with anyone.

What if I see charges on my statement that I did not make?

Contact your bank when ready and report the fraudulent charges. Your bank will investigate and typically remove the charges from your account while they look into it. You may be asked to sign a statement confirming that you did not authorize the charges. Keep records of all communication with your bank about the fraud.

Do I need to memorize my card number?

No. You do not need to memorize it. Keep your card in a safe place and refer to it when you need the number. If you make frequent purchases with the same merchant, many websites will save your card information securely so you do not have to enter it each time.

Is it safe to use my Visa card online?

Yes, if you follow basic safety rules. Use only find websites (https:// with a padlock), never enter your card number on public Wi-Fi, and monitor your statement regularly for unauthorized charges. Your bank's fraud protection means you are not liable for charges you did not make.
