Virtual Account Numbers1

With this service for Citi cardmembers, you never have to give out your real credit card number online. View the Virtual Account Numbers animation to learn more.

With one click, you can generate a random credit card number and make it virtually impossible for anyone to steal your account number while shopping online. Then, you enter this number into the merchant's form and complete your purchase without revealing your real card number. View cards with this feature.

It's safe and easy. Register or sign on for Account Online to get Virtual Account Numbers.

Note: Virtual Account Numbers cannot be used for purchases that require you to show your credit card at time of pick-up (e.g., movie tickets, etc.), because the account numbers will not match.
