To change your UPI mobile number, you must first update your mobile number in your bank records. Visit your bank branch or use their official net banking portal to complete the KYC update. Once the new number is linked to your bank account, follow these steps:
- Uninstall and reinstall your UPI application to reset the existing profile.
- Select the new mobile number to verify your account via SMS.
- Select your bank and re-link your accounts to generate a new UPI ID.
