Virtual Credit Cards: The Smartest Way to Shop Online Without Risking Your Real Card

Every time you enter your credit card number on a website, you're trusting that merchant to store it securely. Data breaches at retailers, restaurants, and online stores expose millions of card numbers every year. Virtual credit cards solve this problem elegantly: instead of giving merchants your real card number, you give them a unique virtual number that's linked to your account but separate from it.

The most powerful feature of virtual cards is merchant locking. When you create a virtual card locked to a specific merchant — say, a streaming service — that card number can only be charged by that merchant. If the number is stolen in a breach, it's worthless to a thief trying to use it at a different merchant. The stolen number simply won't work anywhere else.

Privacy.com offers free virtual cards for US users — up to 12 per month on the free plan. You can set spending limits, lock cards to specific merchants, and freeze or delete any card instantly. Several major credit card issuers also offer virtual card features: Capital One's Eno, Citi's Virtual Account Numbers, and Apple Card's virtual numbers for non-Apple Pay purchases.

Virtual cards are particularly valuable for: free trial subscriptions (create a card with a $0 limit so the merchant can't charge you after the trial), one-time purchases from unfamiliar merchants, and any subscription where you want to control exactly when and how much can be charged. They're also useful for international purchases where your real card might trigger fraud alerts.

One limitation: virtual cards don't work everywhere. Some merchants, particularly those that require card verification for in-person pickup or car rentals, may reject virtual card numbers. For these situations, your real card is still necessary. But for the vast majority of online purchases, virtual cards are the safest option available.
