Is FASTag recharged by mobile number?

FASTag can be recharged using various methods, including bank portals, authorized apps, and other online payment platforms. While the account is linked to your vehicle and often to a registered mobile number for communication, the recharge process usually involves the FASTag account number, wallet ID, or vehicle registration number. You typically use payment methods like Net Banking, credit/debit cards, or UPI to add funds to your FASTag balance.
