What a virtual credit card is and how it works
A virtual credit card is a temporary card number linked to your real credit card account. When you request one from your card issuer, you get a unique 16-digit number, expiration date, and CVV code that work like a physical card—but only for online purchases, and only for the amount and time period you set.
The virtual number routes to your actual account behind the scenes. When you use it to buy something online, the merchant sees the virtual number, not your real card number. If that virtual number gets stolen or the merchant is breached, the thief has a number that either has already expired or is locked to a single merchant and a single purchase amount.
Your real card number stays in your wallet. You control when the virtual number works, how much it can charge, and which website it's tied to. Once you're done using it, you can delete it or let it expire.
Key Takeaways
- Virtual card numbers are temporary, single-use or limited-use numbers that connect to your real credit card account but hide your actual card details from merchants.
- You set spending limits and expiration dates on each virtual card, so a breach of the merchant's system exposes only that limited number, not your full account.
- Most major card issuers offer virtual cards through their mobile app or online account portal at no extra cost.
- Virtual cards work for online shopping, subscriptions, and free trials, but not for in-person purchases, gas pumps, or ATM withdrawals.
- A virtual card is not the same as a prepaid card—it draws from your credit line and builds your credit history the same way your physical card does.
How to request and set up a virtual card
The process varies slightly by issuer, but most let you generate a virtual card directly in their mobile app or online banking portal. Log into your account, look for a section labeled "Virtual Cards," "Card Controls," or "Digital Wallet," and select the option to create a new virtual number.
You'll be asked to set a spending limit and an expiration date. Some issuers let you tie the virtual card to a specific merchant (so the number only works at that one website), while others let it work anywhere online. You can usually set the card to expire after a single transaction, after 30 days, or on a date you choose.
Once you confirm, the issuer generates the number when ready. You copy it into the checkout form just as you would a physical card number. Some issuers also let you add the virtual card to digital wallets like Apple Pay or Google Pay for faster checkout.
If your issuer doesn't offer virtual cards through their app, call the customer service number on the back of your physical card and ask whether they provide them. Not all issuers offer this feature yet, though the major ones—Chase, American Express, Capital One, Citi, and Bank of America—do.
When virtual cards protect you and when they don't
Virtual cards are most useful when you're shopping at a new or unfamiliar merchant, signing up for a free trial that requires a card on file, or buying from a website you don't fully trust. If the merchant's database is hacked, the thief gets a card number that either has already expired or is locked to a $15 purchase at that one store.
They also work well for recurring subscriptions. Instead of giving a merchant your real card number that they store and charge repeatedly, you can give them a virtual number set to expire at the end of your subscription period. When you cancel, the number stops working automatically.
Virtual cards do not protect you against fraud you commit yourself—if you authorize a charge and then claim you didn't, the issuer will still hold you responsible. They also don't shield you from a merchant's poor security if you've already given them your real card number in a previous transaction. And they offer no protection at the gas pump, at an ATM, or in a physical store, since those require a physical card.
Virtual cards are also not a substitute for monitoring your account. You still need to check your statements regularly and report unauthorized charges within 60 days of the statement date to stay within the legal window for disputing them.
Virtual cards versus other security tools
Virtual cards are one layer of protection, but they work alongside other tools. A password manager stores your login credentials so you don't reuse passwords across sites. Two-factor authentication (a code sent to your phone or generated by an app) prevents someone from accessing your account even if they have your password. Credit monitoring services alert you if someone tries to open a new account in your name.
Virtual cards are narrower in scope than these tools—they protect only the card number itself, not your login or your identity. But they're also simpler to use. You don't have to remember anything or change your behavior; you just generate a number and use it once.
If you're shopping at a major, well-known retailer with strong security practices, a virtual card adds little extra protection beyond what your card issuer's fraud monitoring already provides. But for smaller merchants, unfamiliar sites, or situations where you're hesitant to hand over your real number, the extra step takes seconds and costs nothing.
How virtual cards affect your credit score
Virtual cards are linked to your real account, so they report to the credit bureaus the same way your physical card does. A purchase made with a virtual card counts toward your credit utilization (the percentage of your credit limit you're using), and it appears on your statement as a charge from that merchant.
Paying off a virtual card charge on time helps your credit score just as much as paying off a physical card charge. Missing a payment or carrying a balance hurts it the same way too. From a credit-building perspective, there is no difference between the two.
The only scenario where virtual cards might affect your credit differently is if you use them to test whether a merchant will charge you before you've fully committed to a purchase. Some merchants place a small hold on your card to verify it's valid. If you do this repeatedly across many merchants in a short time, it could temporarily lower your score by a few points, but the effect is usually minor and temporary.
Limits and fees for virtual cards
Most card issuers offer virtual cards at no extra cost. There are no monthly fees, no per-card fees, and no set up fees. You pay the same interest rate and annual fee (if any) on charges made with a virtual card as you do on charges made with your physical card.
The main limits are practical rather than financial. You can usually create only as many virtual cards as your issuer allows—some cap you at 10 active cards at a time, others at 50. You can't use a virtual card for in-person purchases, recurring bills that require a physical card on file (like insurance or utilities), or international transactions at some merchants.
Some issuers also limit the spending cap you can set on a single virtual card. If your credit limit is $5,000, you might only be able to set a virtual card to $2,500 or $3,000. Check your issuer's terms to see what limits explore to your account.
Virtual cards versus prepaid cards and digital wallets
A virtual credit card is not the same as a prepaid card. A prepaid card is a separate account you load money into in advance; it's not connected to a credit line, and it doesn't build your credit history. A virtual credit card is a temporary number tied to your existing credit account, and it works exactly like your physical card from a credit perspective.
A digital wallet (Apple Pay, Google Pay, Samsung Pay) is also different. A digital wallet stores your physical card information securely on your phone and encrypts it when you use it to pay online or in stores. A virtual card is a separate number that your issuer generates for you. You can add a virtual card to a digital wallet if your issuer and wallet support it, but they serve different purposes.
Digital wallets protect your card number at the point of sale by using tokenization—the merchant never sees your real number. Virtual cards protect your number by giving you a temporary, limited number to hand over in the first place. Both reduce the risk of your real card number being exposed, but they do it in different ways.
Frequently Asked Questions
Can I use a virtual card at a physical store or gas pump?
No. Virtual cards work only for online purchases. At a gas pump, ATM, or physical store, you need your physical card or a digital wallet. Some issuers are testing virtual cards for in-person use through digital wallets, but this is not yet standard.
What happens if I forget to set an expiration date on my virtual card?
Most issuers set a default expiration date if you don't choose one—usually 30 days or 90 days from creation. Check your issuer's settings to see what the default is and whether you can change it after the card is created.
Can I reuse the same virtual card number for multiple purchases?
It depends on how you set it up. Some issuers let you create a virtual card that works for multiple purchases up to a spending limit you set. Others let you create single-use cards that expire after one transaction. Check your issuer's options when you generate the card.
Do virtual cards help if a merchant gets hacked?
Yes, but only partially. If the merchant's database is breached and the thief steals your virtual card number, they get a number that either has already expired or is locked to a low spending limit and that one merchant. Your real card number stays safe. However, if you've given the merchant your real card number in a previous transaction, a breach could still expose that.
Will using virtual cards lower my credit score?
No. Virtual card charges report to the credit bureaus the same way physical card charges do. Paying them on time helps your score; missing payments hurts it. There is no credit penalty for using virtual cards instead of your physical card.
