Code 128

<p>Code 128 is a high-density <a href="/facts/Linear_barcode/Mkh4cCTp">linear barcode</a> symbology defined in ISO/IEC 15417:2007. It is used for <a href="/facts/Alphanumeric/ytA9RSIv">alphanumeric</a> or numeric-only <a href="/facts/Barcode/Mkh4cCTp">barcodes</a>. It can encode all 128 characters of <a href="/facts/ASCII/vGUI33Qu">ASCII</a> and, by use of an extension symbol (FNC4), the Latin-1 characters defined in <a href="/facts/ISO%2fIEC_8859-1/xPNVSEE6">ISO/IEC 8859-1</a>. It generally results in more compact barcodes compared to other methods like <a href="/facts/Code_39/49a4XzMm">Code 39</a>, especially when the texts contain mostly digits. Code 128 was developed by the Computer Identics Corporation in 1981.
