How VAHAN counts registrations (and what it misses)
·Autiqa Editorial·8 min read
A plain-language guide to Parivahan monthly files — RTO timing, re-registrations, and why Autiqa normalises before Lens charts update.
VAHAN is India's authoritative vehicle registration system. Public monthly extracts count new registrations by maker, fuel, state, and vehicle class — for 4W PV, that's the signal Autiqa builds on.
Lag matters: an "April" file often includes late-March RTO uploads. Autiqa applies maker normalisation and fuel mapping before Lens refreshes so MoM comparisons stay apples-to-apples.
