What a virtual credit card is and why you might want one
A virtual credit card is a temporary card number linked to your real credit card account. Instead of using your actual card number online, you generate a unique number that works only once or for a single merchant. When that number is compromised or you stop using it, your real account stays protected.
Virtual cards solve a real problem: every time you enter your card number on a website, you're trusting that site to keep it safe. Data breaches happen. Virtual numbers let you shop online without that risk. The charge still comes from your real account, but the merchant never sees your actual card number.
Some virtual card services also let you set spending limits on each number, see exactly which merchant charged you, and block future charges from that vendor instantly. This is different from a physical card — you cannot use a virtual number in a store or at an ATM.
Key Takeaways
- Virtual card numbers are generated by your credit card issuer or a third-party app and mask your real card number during online purchases.
- Most major credit card issuers now offer virtual numbers for free as a built-in feature, usually through their mobile app or website.
- If your card issuer does not offer virtual numbers, standalone apps like Privacy, Blur, and Masked let you create them for a subscription fee.
- Virtual numbers work only for online purchases and subscriptions, not in physical stores or at ATMs.
- Using a virtual number does not affect your credit score or credit history — the charge reports under your real account as normal.
Getting virtual cards through your credit card issuer
Start by checking whether your card issuer already offers this feature. Most major issuers — including Capital One, Chase, American Express, and Discover — now include virtual card numbers at no extra cost. Log into your account online or open the mobile app and look for a section labeled "Virtual Card," "Card Controls," "Secure Shopping," or "Card Numbers."
If the feature exists, you can usually generate a new number in seconds. The app will show you the virtual card number, expiration date, and CVV, just like a physical card. Some issuers let you set a spending limit before you generate the number, choose which merchant it works with, or set an expiration date (anywhere from one transaction to several months).
The process differs slightly by issuer. Capital One's Eno service works through a browser extension that detects when you are checking out online and offers to generate a number automatically. Chase's virtual card feature lives in the Chase Mobile app under "Card Controls." American Express lets you create numbers through their website. Check your issuer's help section or call the number on the back of your card to confirm they offer this and where to find it.
Using third-party virtual card apps if your issuer does not offer them
If your card issuer does not have a built-in virtual card feature, you can use a standalone app. These apps sit between you and the merchant, generating a new card number for each purchase and forwarding the charge to your real card. The most common options are Privacy, Blur (from Abine), and Masked.
Privacy and Masked both charge a monthly subscription — typically around $10 to $15 per month, though both offer free trials. Blur charges a one-time fee or a monthly subscription depending on which features you want. To use any of them, you download the app, link your credit card, and then generate a virtual number when you are ready to check out. The app handles the rest.
These apps work with most major credit cards and most online retailers. However, they add a step to checkout and require you to trust the app company with your card information. Read the privacy policy carefully before you sign up. Some people use them only for high-risk purchases (unfamiliar websites, subscription services they plan to cancel) rather than for every transaction.
How virtual numbers protect you during checkout
When you use a virtual number, the merchant receives that temporary number instead of your real card number. If the merchant's database is hacked, the thief gets a useless number — it either does not work anymore or works only for that specific merchant. Your real card number stays safe in your issuer's system.
This protection matters most for subscriptions and recurring charges. You can generate a virtual number specifically for a streaming service or gym membership. If you cancel the subscription but forget to update the payment method, the merchant cannot charge you because the virtual number no longer works. You avoid surprise charges and do not have to contact the company to remove your card.
Virtual numbers also give you a paper trail. Instead of seeing "Unknown Merchant Inc." on your statement, you can track exactly which virtual number was used and match it to which website. This makes it easier to spot fraud or unauthorized charges and dispute them with your issuer.
What virtual cards cannot do
Virtual numbers work only for online purchases and subscriptions. You cannot use them at a physical store, gas pump, or ATM. If a merchant requires a physical card for verification (some hotels and rental car companies do this), you will need your real card.
Virtual numbers also do not change how your credit report works. The charge still reports under your real account and counts toward your credit utilization, payment history, and credit score exactly as if you had used the physical card. Using virtual numbers does not build credit or hurt it — it is purely a security tool.
Some merchants block virtual numbers or require a real card for their first transaction with you. This is rare but happens occasionally with certain subscription services or international retailers. If a virtual number is declined, you will need to use your real card instead.
Setting up virtual numbers for subscriptions and recurring charges
Virtual numbers are especially useful for subscriptions because you can create a unique number for each service. Generate one number for your streaming service, another for your gym, another for a software trial. If you cancel the subscription, that number stops working and the merchant cannot charge you again.
When you set up a virtual number for a subscription, check whether your issuer or app lets you set an expiration date. Some let you choose when the number expires — for example, you could set it to expire 30 days after the first charge, forcing the merchant to ask for an updated payment method if they want to keep billing you. This is a good safety net if you forget to cancel.
Keep a note of which virtual number you used for which service. Your statement will show the merchant name, but if you need to update your payment method or troubleshoot a failed charge, knowing which number you used helps you contact the right company quickly.
Frequently Asked Questions
Do virtual card numbers hurt my credit score?
No. Virtual numbers are just a different way to use your real card. The charge reports to your credit history under your actual account, and it affects your credit score the same way a physical card charge would. Using virtual numbers does not build credit or damage it.
Can I use a virtual number at a store or restaurant?
No. Virtual numbers work only for online purchases and subscriptions. At a physical location, you must use your real card or another payment method like cash or a digital wallet.
What happens if a merchant refuses my virtual number?
Some merchants, especially international retailers or subscription services, occasionally decline virtual numbers. If this happens, you will need to use your real card instead. This is uncommon but can occur with certain vendors.
If I lose my phone, can someone use my virtual numbers?
Virtual numbers are tied to your account, not your phone. If you lose your phone, log into your account from another device and delete or deactivate any virtual numbers you created. You can also contact your card issuer to lock your account. The virtual numbers themselves cannot be used without access to your account.
Do I need a good credit score to get virtual card numbers?
No. Virtual numbers are a feature of your existing credit card account. If you already have the card, you can use virtual numbers. You do not need to meet any additional credit requirements or go through a separate approval process.
