If you have a barcode, but don't know what type of barcode it is, this website can help you get the type of barcode. On this website, you don’t need to scan and upload the picture of your barcode to the website.
In general if the items are to be scanned or sold via retail then the best barcode type to use would be the UPC or EAN barcodes. Consider also the amount of data that you require, if alphanumeric is required then Code 39 or code 128 is the best option.
The Barcode Checker tool allows you to instantly verify the authenticity of any product by entering its barcode number (EAN, UPC, ISBN, or GTIN). It retrieves verified product data such as brand, manufacturer, origin country, and category.
The simplest way to identify a barcode type (symbology) is to scan the barcode with the Barcode Decoder Verification App because it identifies common barcode types and recommends products that generate that barcode type.
