UPC-E Barcode Introduction

UPC-E barcode is a compact form of UPC-E. It is both self-checking and omni-directionally decodable. In addition, UPC-E is space-efficient since it reduces data length from 12 digits to 6 by compressing extra zeros, as a result it is suitable for items with small packaging. To encode supplementary information, a 2-digit or 5-digit Add-On Symbol can be added to a UPC-E symbology.

Encodable Chars	UPC-E barcode can encode numeric digits through 0 to 9.
Checksum Digit	Though UPC-A is character self-checking, a mandatory modulo 10 check digit is required in the standard. The checksum will be added automatically by our products.
Add-on Symbols	A two-digit or five-digit add-on symbol can be added to a UPC-A symbology to encode supplementary information.
Guard Bar Pattern	The UPC-E data is separated by two Normal Guard Bar Pattern, which are encoded as 101, and a Special Guard Bar Pattern encoded as 01010.

To set the size of UPC-E, two things are of importance, i.e. the X Dimension and the barcode width.
