Consider Using Single-use Card Numbers

Consider Using Single-use Card Numbers

Consumers using some brands of credit cards can get “virtual credit cards,” or single-use card numbers, that can be used at an online store. The randomly generated substitute 16-digit number can also be used to buy goods and services over the phone and through the mail but can’t be used for in-store purchases that require a traditional plastic card.

With this free service, you never need to give out your real credit card number online. Among the card companies offering it are Citibank and the Discover card.
