How to activate multiple UPI IDs?

A single bank account can have multiple UPI IDs, but true personalization is limited to selecting from system-generated options. To get multiple UPI IDs, link your bank account to a UPI or merchant app. The app, through its Payment Service Provider (PSP) bank, will generate several predefined ID options from which you can choose and activate one. For instance, on the Paytm app, you can choose from options like @pthdfc or @ptaxis.
