Google warns old Paytm UPI handles are defunct

Google alerted Android users that old '@paytm' UPI handles are no longer functional. This change, effective August 31, 2025, is due to regulatory orders requiring Paytm to route payments through banks, changing handles to options like '@pthdfc'. Users should update their UPI handles to new ones like '@pthdfc' or '@ptsbi' before subscription renewals to avoid payment disruptions.
