## What the Engine to RC Details API does

Engine to RC Details resolves an engine number to the vehicle's registration record and returns the associated details.

Engine and chassis numbers are the two physical identifiers stamped on a vehicle. Being able to search on either matters in practice, because one is frequently obscured, corroded or simply hard to reach during an inspection.

## Where teams use the Engine to RC Details API

1.  Identifying a vehicle when the chassis number is unreadable
    
2.  Cross-verifying engine number against the registration record
    
3.  Vehicle inspection in claims and used-vehicle sales
    
4.  Detecting mismatches between engine and registered vehicle
    

## Frequently Asked Questions (FAQs)

When would I use engine rather than chassis?

Usually when the chassis stamp is inaccessible or corroded. Where both are available, checking both is the stronger verification.

What does a mismatch indicate?

An engine number that resolves to a different vehicle than the chassis suggests a replaced engine or, more seriously, a tampered identity. Investigate before proceeding.

Is the engine number on the RC?

Yes, alongside the chassis number, which lets you compare the document against the physical vehicle.
