Virtual card numbers are unique credit card numbers that you can use to pay for an online purchase instead of using your actual card number. Virtual card numbers can make online shopping easier and more secure. They only work at a single merchant site, adding a layer of protection to your credit card account in case a merchant that stores your credit card number is ever compromised. 

Virtual card numbers are still linked to your credit card account, so you’ll still enjoy the same card benefits or earn the same rewards (for eligible rewards cards).

If you’re a Capital One credit card customer 2, first add the Eno browser extension to your desktop browser. Once the extension is installed, sign in using your Capital One credentials, then enroll using your credit card(s).

The next time you’re ready to check out online, you can use Eno to generate a merchant-specific virtual card number to complete your purchase. Each virtual card number can only be used at one merchant site, giving you added security. For added control, you can lock, unlock, and delete your virtual card numbers at any time.

The transactions you make using virtual card numbers will show up normally on your monthly statements.
