What is a CVV on a debit card?

You can think of debit cards as an electronic version of cash.💸 They’re connected to your bank account and transfer money to other accounts to conveniently pay for things. So you can shop, transfer money to savings, and pay bills.

Since debit cards provide access to the money in your debit account, they’re important to keep secure. CVV numbers are one of their built-in security features. 

A CVV code — AKA a card verification value — is the security code found on the back of your debit card that helps encode your banking information. 

Still have questions? Don’t worry. In this blog post, we’ll cover everything you need to know about CVVs, keeping your info safe, and the difference between CVVs and CVCs. 

What is a CVV on a debit card? And what does it do?

If you’ve ever shopped online and been asked for a security code and thought, ‘What is the security code on a debit card?’ or ‘Is a security code the same as a CVV?’ — Allow us to explain.

A CVV is a security code typically found on the back of your debit card on the signature panel. Locate it by flipping over your card and looking for the three or four-digit code on the back. Think of the CVV code as a way to authorize your purchases. If someone gets ahold of your card number but doesn’t have your security code, they’ll have a more challenging time using your info to buy things online. 

When it comes to a CVV vs CVC — they function the same. CVV is a term used by Visa, and CVC is the term used by Mastercard. Feel free to use them interchangeably.

Pro tip: Both debit and credit cards use CVVs or CVCs to keep your info secure. Make sure to locate the code on each of your cards.

Understanding the CVV number

Let’s talk details. Now that you know what a CVV number is — and where to find it on your card — let’s discuss how it works.

CVV numbers are generated by your bank when they issue your debit card. In the same way you enter your PIN number to use your debit card in person, you use your CVV to authorize purchases online. Ultimately, entering your CVV proves you have the physical card in your possession when making online payments.

Retailers are not allowed to store your CVV in their systems, making it difficult for others to use your info for fraudulent purchases — even in the event of a breach.

When do you need to use your CVV?

CVVs are used to verify online or remote purchases. You’ll typically be asked to provide your CVV or CVC and a cardholder name when buying things on your phone, computer, or phone call. However, it’s important to know that not every retailer requires a CVV.

5 tips to keep your debit card secure

In addition to your debit’s built-in security, there are several things you can do to protect your banking information. Use these 5 tips to keep your transactions secure. 

1. Keep your PIN and CVV to yourself

PIN numbers and CVV codes grant access to your bank accounts, so prioritize keeping these numbers secure. The key? Don’t tell anyone the codes, and avoid writing them down — even in your notes app. 

2. Sign your card

While CVVs help keep your card safe from fraudulent online purchases, it’s still possible for your information to be taken. Suppose someone makes a fraudulent card with your information or steals your physical debit card. In that case, a signature will help retailers identify the fraud by comparing the signature on a signature pad to the signature on the card.

3. Monitor your account

Check your debit account regularly to make sure each purchase is legitimate. If a fraudulent purchase — or an incorrect amount — shows up on your statement, contact your bank right away. 

4. Only purchase from trusted merchants

Use your best judgment when making online purchases to avoid untrustworthy retailers. How? Make sure the website looks legitimate, check reviews, and see if the company requires your CVV — which helps protect your banking info. 

5. Protect your physical card

The easiest way to protect your CVV? Keep track of your debit card. Contact your bank immediately to cancel and reorder your card if you lose it — or think you may have lost it.
