Here’s what’s on the site to pay by a prepaid gift card like Visa gift:

Your prepaid card is fully activated by following the instructions enclosed with the card (if applicable).

You use the same zip code as you registered with your card during the checkout process.

You use a valid name and do not use a name such as “Gift Card”.

You use a valid address.

You use a valid phone number.

Not sure the last two are enforceable.
