To know all your UPI IDs, you can check the settings within your linked payment applications or bank's mobile app. Since UPI IDs are linked to specific bank accounts, you can view them by following these steps:
- Open your preferred UPI enabled application and go to the Profile or My Account section.
- Select Payment Settings or Bank Accounts to see a list of linked accounts.
- Tap on a specific bank account and select Manage UPI IDs to view all active IDs associated with that account.
You can also find your primary UPI ID displayed on the home screen or profile page of most UPI apps.
