Free online GS1 AI Decoder

Upload a GS1 barcode and this free online tool will provide a breakdown of its component strings (AIs) such as GTIN, Batch Code, Serial Number, Use-by Date, etc.

Take the results with a grain of salt, we are still testing. Please be aware that we currently do not check for the existence of a GS1 Symbol Identifier in DataBar, Composite, DataMatrix or QRCode barcodes.
Please send us a message if you have a case where you think our results are wrong or incomplete.

Max. file size for upload is 2 MB. Supported file types: pdf, tiff, jpg, png, bmp, jpeg.
Use this input if you have a text string instead of a barcode image. Enclose AIs in ().
