privacy.com It's free and it works. I've been using it for years to create unique credit cards. You can set a limit on spending, and you can close the card whenever you want. Furthermore, on those forms that ask for your PII as well as the credit card, you can give whatever name & address you want. Those aren't verified. (Of course, if they're actually going to mail something to that address, it's another matter, but often the "shipping address" is separate.)
