>- Virtual card numbers can you create your own?

Probably a temporary CC number generator for internet purchases.

You would not be able to "choose" a vanity number of your own choosing besides being really insecure but also because CC numbers have to fit an algorithmic pattern to be valid: https://en.wikipedia.org/wiki/Luhn_algorithm

Wasn't expecting a vanity number but creating a different number for each service. Something like what capital one has [1]. There would be a number for Netflix and a different number for fios.

Oh, lots of card issuers have that these days.

No, each “purchase” gets its own code to keep them separate to merchants.

Probably not. This is exactly how Apple Pay works - every physical card you add to apple pay is added to your phone/watch/laptop with a different number. If you delete card from your phone and add it again, its has yet another number.

All those unique numbers are handled by your bank and linked to single card account.

Didn’t say. The card number will be unique to each device though.
