FASTag Verification & Balance API
Validate a vehicle's FASTag, check status and balance, and map a number plate to its tag — in real time.
FASTag is mandatory for toll payments on Indian highways, which makes it a useful signal about a vehicle and its owner. FASTag APIs let you confirm a vehicle has an active tag, check its status and balance, and map a number plate to its FASTag details — valuable for fleets, auto lenders and logistics platforms.
What you can check
- FASTag status — active, blacklisted or low-balance.
- Available balance on the tag.
- Toll/transaction history for the vehicle.
- Mapping a number plate to its FASTag details.
