VIN Decoder: VIN Scanner helps you scan a VIN and unlock factory specs in seconds. THREE WAYS TO CAPTURE A VIN - Point the camera at printed or stamped VIN text — on the windshield, door jamb, dashboard, or documents. Clear handwriting works too. - Flip on Barcode mode for the bare Code 39 stripes and Data Matrix squares on door-jamb stickers. - Type the 17 characters by hand when a VIN plate is dirty, scratched, or out of reach. Every VIN is validated on your device before anything is sent anywhere: a bad scan is caught instantly, with a clear reason why. WHAT'S IN YOUR REPORT - Factory specifications for the decoded vehicle: make, model, model year, trim, body type, engine, cylinders, fuel type, drive type, transmission, plant and manufacturer details, doors, and more — sourced from Official NHTSA data. - Possible official NHTSA recalls for this decoded make/model/year. Recall campaigns match the decoded make, model, and model year — this is not a repair-status certificate for your exact VIN. This app does not certify title status, theft status, accident history, ownership, mileage, liens, or parts compatibility. SIMPLE, HONEST PRICING This app is paid-before-result: there is no free decoding of a VIN you scan or enter, and no surprises after. One built-in sample VIN shows the full report format as a free demo before you buy. Then choose what fits: - A single report for the one car you're serious about - A pack of 3 or 10 reports for a shopping weekend - VIN Pro, an auto-renewable subscription (monthly or yearly), for unlimited* reports while you hunt *A fair-use limit applies to VIN Pro to prevent automated abuse; normal personal use is unaffected. NO LOGIN. NO ADS. No sign-in, no password, no Sign in with Apple — your purchases and report history are tied to an anonymous on-device account. There is no advertising anywhere in the app. YOUR DATA, YOUR CONTROL Reports are cached on your device for offline viewing. From Settings you can delete saved reports or your server-side data at any time. Data source: Official NHTSA data. NHTSA is referenced only as the public source for vehicle specification and recall data — this app is not affiliated with, endorsed by, or a partner of NHTSA or any vehicle-history provider. — Subscription Terms VIN Pro is offered as a monthly or yearly auto-renewable subscription. Payment is charged to your Apple ID account at confirmation of purchase. Your subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period; your account will be charged for renewal within 24 hours prior to the end of the current period. Manage or cancel your subscription anytime in your Apple ID account settings. Privacy Policy: https://acty.dev/apps/vin-decoder/privacy/ Terms of Use: https://acty.dev/apps/vin-decoder/terms/
