Hello Yeswanth,

If you have misplaced your challan number after applying for your 2nd PU migration certificate, you can retrieve the challan number in any one of the following ways:

1. Look back at your bank receipt or transaction history - The challan/reference number is often mentioned.
2. Log in to the payment portal - The educational boards often display a "Track Payment" or "Reprint Challan” option.
3. Go to your PU college or Pre-University Board’s office - Provide your payment details (date of payment, amount, bank and account number) so that they may trace your challan.
4. Check with the bank branch which you used to pay the fees - The bank should also be able to look up the challan number from their records.

Remember to always keep a soft copy or screenshot of the challan for your own future needs.

If you have lost your challan number after making the payment for the Second PU migration certificate in Karnataka, you can still recover it. First try checking the Khajane 2 portal where the payment was made. You can visit the Khajane 2 website and check your payment history using the details like your name or mobile number used during payment. If that does not help, you should contact your college or the PU board office directly. Provide them with your payment date and student registration details. They will be able to help you retrieve the challan number or guide you with the next steps. Keep your future payment records safe for easy reference.
