1D / linear barcodes

Linear (1D) barcodes encode data as a pattern of parallel bars and spaces, read by a single scan line. They are the most widely deployed barcode family, favored for their scanner compatibility and low print-resolution requirements.

Choosing a format

• Code 128 is the general-purpose choice for alphanumeric data in logistics and shipping.
• Choose a retail-specific symbology (EAN-13, UPC-A) when the data must be a globally recognized product identifier.
• Linear symbologies generally need more printed width than an equivalent 2D symbol for the same payload.
