Search for a product, paste a barcode, or scan one to see results here.

Barcode tools

Live camera scanning is still experimental and may not work yet on some devices and browsers, including iPhone browsers and older Mac browsers. If camera scan fails, use barcode paste or upload a barcode photo instead.

Paste a barcode

This is the most reliable option if you already have a scanner, typed code, or copied barcode number.

Upload a barcode image

Tip: crop close to the barcode with good lighting and as little glare as possible.
