Fastag Lookup API
Retrieve FASTag information for a vehicle, including tag status and the details registered against it, for vehicle verification and fleet onboarding.
What the Fastag Lookup API does
Fastag Lookup returns the FASTag information held for a vehicle, including the tag's current status and registration details.
For fleet operators this is operational rather than investigative. A blacklisted or inactive tag causes delays and penalties at toll plazas, and catching it before dispatch is considerably cheaper than dealing with it en route.
Where teams use the Fastag Lookup API
Checking tag status before dispatching a vehicle
Managing FASTag across a commercial fleet
Verifying tag registration during vehicle onboarding
Identifying blacklisted or inactive tags
Frequently Asked Questions (FAQs)
What does a blacklisted tag mean?
The tag cannot be used for toll payment, commonly due to insufficient balance or a registration issue. It causes delays and penalties.
How does this differ from Fastag To RC?
That endpoint maps a tag to a vehicle. This returns tag information for a vehicle.
Can I see toll history?
Use FASTAG History Verification for recent toll plaza activity.
