Code 11 Introduction

This page concerns basic information of Code 11, as well as its generating and printing components.

Code 11 Overview

This part talks about the Code 11 barcode. Code 11, also known as USD-8, is a high-density barcode symbology developed by Intermec in 1977 to numeric digits. It was primarily used to label telecommunication equipments. This symbology is discrete and is able to encode numeric digits through 0-9, dash (-), and start/stop characters.

Generating and Printing Code 11 Barcodes

OnBarcode provides comprehensive Code 11 generators and scanner components for Java, .NET, Android, iOS developments and several reporting applications.

Code 11 Structure

The structure of Code 11 is as below:

Code 11 Barcode Size Setting

As for Code 11 size setting, three factors should be considered: module width (i.e. X dimension) barcode width and height.

Code 11 Data Encoding

Code 11 encodes:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • Dash (-)

Code 11 Barcode Checksum Digit

Code 11 is not very secure because imperfect printing may convert one character in the image into another. In this case, a Code 11 symbol may require one or even two check characters (optional). One checksum digit is highly recommended for enhancing data security.
