Free VIN Decoder Widget

Live demo

This is the widget itself, rendered on this page. Try a VIN, for example 1HGCM82633A004352 (a 2003 Honda Accord).

Embed it

Paste this where you want the decoder to appear:

<div class="vdc-vin-widget"></div>
<script src="https://vindecodercheck.com/widget.js" async></script>

That is the whole integration. The script finds every vdc-vin-widget div on the page, so several widgets need only the one script tag.

Attributes

Attribute	Meaning
data-vin	Pre-fill a VIN and decode it as soon as the widget loads, e.g. data-vin="1HGCM82633A004352".
data-endpoint	Override the API base URL. Defaults to https://vindecodercheck.com/api/vin/; useful if you proxy the API through your own domain with an IPNOVA key.

How it works

The widget renders inside a Shadow DOM with self-contained styles, so nothing leaks in or out of your page's CSS.
Decodes call the free VIN decoder API directly from the visitor's browser (CORS is open), so each visitor spends their own allowance of 100 decodes a day, not yours.
Data comes from the official NHTSA vPIC database (US public domain), served from our permanent cache after a VIN's first decode.
Full 17-character VINs decode completely; partial VINs of 11 or more characters decode structurally.
Results link to the vehicle's specs-and-recalls page on VinDecoderCheck when we have one.
VINs are never logged. Build facts only: no ownership, title or accident data, ever.
Dynamic pages can call window.VDCWidget.render() after inserting new widget divs.

Terms

Free for any site, commercial or not, on one condition: the "Data by VinDecoderCheck" attribution link the widget renders stays visible and clickable. If you need higher volumes or want the data server-side, use the VIN decoder API with a free key from api.ipnova.com.

Frequently Asked Questions

Embedding the free VIN decoder widget

Is the VIN decoder widget really free?

Yes. No API key, no registration, no account. Copy the snippet and it works. Decodes count against each visitor's own free allowance of 100 requests a day, and the only requirement is keeping the VinDecoderCheck attribution link visible.

Will it clash with my site's CSS?

No. The widget renders inside its own Shadow DOM with fully self-contained styles, so it never reads or leaks CSS from the host page.

Where does the vehicle data come from?

The official NHTSA vPIC database, US public domain. Each VIN is decoded upstream once and then served from VinDecoderCheck's permanent cache. Build facts only: no ownership, title or accident data, and VINs are never logged.
