What is the bank account number that shows on my fundraiser page?

The account number is a virtual UPI account created for your fundraiser through which donors can donate via NEFT mechanism it is not a bank account.

It is just another method to transact--all donations via this method will show up on your donor list and dashboard. Please note the UPI account is only valid for the given fundraiser and is not a new bank account created with yesbank, it is only a virtual account created on Ketto for your fundraiser to accept donations via NEFT.
