Add-5 Barcode Specification
Supported Barcode Types > Barcode Types > Add-5 Barcode Specification

The Add 5 barcode is a numeric 1D barcode that encodes 5 digits of information. It is often used to provide supplemental information about other barcodes, which is why it is also referred to as an "add-on symbol". Add 5 barcodes have no error detection or correction mechanisms.

Example Barcode

The following example barcode encodes the information 54995 as an Add 5 barcode:

Add 5 barcode


The Add 5 barcodes encode exactly five digits of information and has a symbol length of 52 modules. This barcode is similar to the Add 2 barcode in that they are both intended to provided supplementary information concerning a "primary" barcode.

This "primary" barcode (usually a UPC/EAN variant) would generally identify the product, while an Add 5 "add-on symbol", usually to the right of the "primary" barcode, would specify additional information such as the product's edition. 1

This can be seen in the following example:
