Gift Card Number Format For Validation

Is there any way to validate the gift card number? If not, what is the format of gift card?
I generated one for testing and it is 16 digits number. Is that the fixed format for gift card?
For credit card form where we can understand whether each field is valid through “inputEventReceived” callback.
I’m wondering if there is a similar way to validate the gift card number.

As far as I know we don’t have a consistent pattern for the PAN of a gift card. I would imagine that they are all 16 digits, but it’s also possible this could change, so I’m not sure of a way to validate gift cards at this time, unfortunately.
