In short:<\/strong> A barcode standard (symbology) defines which characters and how many digits a barcode can encode. Retail products use the 13-digit EAN-13<\/strong>; numbers issued in Turkey start with 868 or 869<\/strong> and are obtained from GS1 Turkey<\/strong>. For logistics and internal use, standards such as Code 128<\/strong> and Code 39<\/strong> are preferred.<\/div>\n
