For Bob addon rupay different phone number can be selected and the addon card can be added to that numbers upi.
As for Tata Neu card different card number for add on, but while trying to add it to upi says server error. Will try again and update.
Neu Infinity RuPay has different primary & addon number but Millennia Diners has the same number for primary and add on.
Please share which add on cards have different number from primary? Why few cards same add on and why few different?
