What kind of barcode should I use?

That depends on where the barcode will be scanned. Selling products in stores? Retailers usually ask for a UPC-A barcode in the US and Canada, or an EAN-13 elsewhere, carrying your product’s GTIN. A GTIN is a number you get from GS1 – the UPC-A page explains how – and Barcode Producer makes the barcode from it.
