How do I link a 8 or 9 digit UPI number of one bank account with another bank account?
To link the 8 or 9 digit UPI number that you’ve set for one bank account with another bank account:
Note: You will only be able to view & select a bank account to link to a UPI number if you have already activated the UPI ID that is linked to that UPI number for the bank account. For example, if your UPI number 12345678 is currently linked to your @ybl ID, you would need to activate this ID for the bank account that you wish to link to the UPI number 12345678.
