CODE128 is a compact, high-density symbology supporting the full ASCII 128 character set, making it standard for supply chain logistics. CODE39 is older and wider, limited to uppercase letters, digits, and select punctuation.
Use EAN-13 internationally across consumer products or UPC-A if selling predominantly within North American points of sale. Both formats require registered GTIN numbers issued by GS1 for global point-of-sale checkout compatibility.

SVG is an infinitely scalable vector format recommended for commercial packaging, high-DPI label printers, and graphic design software. PNG provides a sharp raster image ready for quick digital embedding, web invoices, and office documents.
