Free AI Scanner

Scan the VIN with your phone
in 3 seconds, no manual entry

Point your camera at the VIN plate. Artificial intelligence will automatically recognize and validate the 17-character number. Works in your browser—no installation, no uploading photos to a server.

The application requires camera access to scan VIN numbers.

Point the camera at the VIN

Works on any phone with a browser. Free of charge.

Manually entering the VIN is a waste of time and a source of errors

A VIN consists of 17 characters—uppercase letters and digits, with no separators. The plate may be dirty, faded, or hidden in a dark corner of the engine bay. A single character mistake means an incorrect vehicle history, wrong report, or failed registration.

ScanVIN.app solves this in one step

Point your camera at the plate—the app locates the number, reads it, and checks its validity. No typing or installation required.

How to scan a VIN? Three steps, a few seconds

  1. Open scanner

Why ScanVIN.app instead of manual entry?

Lightning-fast speed

No more crouching by the door sill and reading character by character. The scanner recognizes the VIN automatically—in real time, without pressing a button.

Accuracy confirmed by validation

Every scanned number is verified: ISO 3779 format, check digit at position 9, manufacturer (WMI) and model year recognition.

Multi-scan mode for difficult plates

When the plate is scratched or hard to read, the app performs a series of scans and assembles the VIN from the most frequently detected characters at each position.

Full privacy

All analysis is performed locally in the browser. No photo is sent to an external server. No third-party API sees your VIN.

Flashlight for dark areas

VIN plate hidden in the engine bay or under the sill? The scanner lets you turn on the flash with one click.

Blur protection

The algorithm checks image stability between frames. Scanning starts only when the camera is steady.

Works on any device

Phone, tablet, laptop—just a modern browser with a camera is enough. No app installation, no account creation, no email required.

Multilingual support

Interface available in multiple languages—use the scanner in your native language.

Who uses the VIN scanner?

Used car buyer

Quickly read the VIN during inspection, no need to crouch with a notepad. Instantly paste the number into a vehicle history service.

Dealerships and car lots

You process a dozen or more cars daily. Every minute saved on rewriting the VIN is real savings. Zero typos means zero documentation issues.

Workshops and service centers

The mechanic scans the VIN with a phone at the workstation. The number goes into the system error-free, and parts orders are based on accurate data.

Insurance and leasing companies

Field agents scan the VIN during inspections. Fewer mistakes, faster document processing.

Fleet companies

You manage dozens of vehicles and regularly need the VIN for reports, inspections, or registration.

Inspectors and appraisers

You verify vehicles in lots, garages, or under poor lighting. The flashlight and multi-scan handle tough conditions.

What powers this scanner?

Behind the simple interface is a pipeline of three AI models running directly in the browser:

VIN Plate Detection

Detection Model

Real-time object detection model locates the plate in the camera frame, even if it's angled or partially obscured.

Text Recognition

OCR Model

Two-stage OCR engine: first detects text areas, then recognizes individual characters. Runs in a Web Worker to avoid blocking the interface.

Number Verification

ISO 3779 Validation

The algorithm checks the format, check digit, manufacturer code (database of over 15,000 WMI codes), and model year. Rejects false readings.

Everything runs on ONNX Runtime Web and OpenCV.js—100% in the browser, with no server involved.

Frequently Asked Questions about the VIN Scanner

Where can I find the VIN in the car?
The most common locations are: lower part of the windshield (visible from outside on the driver's side), driver's door B-pillar, nameplate in the engine compartment, and the registration certificate. The scanner will read the VIN from any of these locations—just point the camera.
Does the scanner work on my phone?
Yes, if you have a modern browser (Chrome, Safari, Edge, Firefox) with camera access. The app automatically checks compatibility and will notify you if something is missing.
Are my photos sent anywhere?
No. All image analysis is performed locally on your device. No data—neither photos nor the read VIN—leaves your browser.
What if the VIN plate is dirty or scratched?
Use multi-scan mode. The app will perform a series of scans and assemble the number from the most frequently recognized characters at each position. You can also turn on the flashlight if lighting is poor.
How much does it cost to use the scanner?
The scanner is free. No registration required, no scan limits, no ads displayed.
Does the scanner recognize the VIN from the registration certificate or invoice?
The scanner is optimized for VIN plates on the vehicle, but it will also read the number from a printed document—provided the font is legible and the number fits within the scanner frame.
What is the VIN check digit?
The ninth character of the VIN is a check digit calculated from the other 16 characters. It helps detect typos and errors. The scanner automatically verifies it with every reading.
