Younger audiences may not remember, but yes: major card providers used provide virtual card numbers back in the day.

This is a feature of the past, and most providers don't do it anymore. The only one I know of is Capital One's Eno: https://www.capitalone.com/digital/eno/virtual-card-numbers/

Wow, I have a Citi card and I never knew! I don't think I've ever been promoted this feature before.

I remember BofA used to. When they closed it, I thought everyone else followed suite.
