## 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

1.  Checking tag status before dispatching a vehicle
    
2.  Managing FASTag across a commercial fleet
    
3.  Verifying tag registration during vehicle onboarding
    
4.  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.
