Will My Paytm FASTag Stop Working, Do I Need to Port It?

Paytm FASTags will not work after 15th March 2024, if they are linked to Paytm Payments Bank. You cannot port your FASTag, but you can get a new one from HDFC Bank. You can use your existing FASTag until the balance runs out. But Paytm is soon migrating the payment model with a partnership with Axis Bank.
