You cannot view or "know" your existing BHIM UPI PIN as it is a secure, encrypted number. If you have forgotten it, you must reset it using your debit card or Aadhaar details.
To reset your PIN:
- Open your UPI app and navigate to the bank account section.
- Select the Forgot UPI PIN or Reset PIN option for the specific account.
- Enter the last six digits and expiry date of your debit card, or verify via Aadhaar if supported.
- Input the OTP sent to your registered mobile number and set a new 4 or 6 digit PIN.
