Most government and dealer VIN lookup sites let you type freely, including characters that aren't even valid in a VIN (no I, O, or Q), and offer no accommodation for quick, one-handed entry.
That freedom to mistype means more errors, more re-entry, and a clunky experience especially on mobile where a full keyboard is overkill for 17 fixed characters.
Replaced the standard keyboard with a constrained T9-style input that only allows valid VIN characters and is built for fast, one-handed entry. The website actually talks to the DMV site, so try your VIN number!
