1D Barcode Structure

The 1D code structure applies to barcodes that you see everywhere, located on products directly or on their tag, label, or packaging. The black and white lines (or stripes) of a barcode contain characters and symbols, depending on the Standard that is being used.

The margins of the barcode are called the “quiet zone” – normally a white space that encapsulates the barcode. It has nothing printed on this area. They are required to be positioned at each end and should be 10 times the thickness of a narrow bar.

The first section is called the “start character”, and the end section is likewise called the “stop character”. These sections indicate the start and stop points in the data. These characters can vary according to the code system being employed.

The data itself is located after the start character. Immediately following the data is a section called the “check digit” or, in some cases, “symbol check character”. The check digit confirms that there are no errors in the reading.


1D Barcode Systems

Some of the code systems that use 1D codes are EAN (JAP), Interleaved 2 of 5, Codabar (NW-7), CODE39, CODE128, and GS1 Databar (RSS). Further information can be found on the DENSO WAVE website, inventors of the QR code.
