What is Code 11?

Code 11 (also called USD-8) is a numeric only barcode developed by Intermec in 1977. The symbology can encode the digits 0 through 9, a dash, and includes both a stop and start character. Code 11 is variable length with the only limit on length being the width available for print. Code 11 is a linear, one-dimensional (1D) barcode. This means the barcode is composed of a single set of varying width vertical lines and spaces. The data in the barcode is represented linearly by these black/white (bar/space) patterns. Below is a simple example.

Each character in a Code 11 barcode consists of 3 bars (black) and 2 spaces (white)—every character starts and ends with a bar.  Of these five elements, two are always “wide” (twice the width of a “narrow” element), and three are always narrow.  The symbology also includes distinct start and stop characters.

The symbology is further characterized as a discrete barcode, meaning that each character is separated with an inter-character gap element (typically a single white element, though larger gaps are permitted).  Here is our example again, diagramed for clarity:

Code 11 is considered a weak or insecure symbology, as a single print or read error can result in a misinterpreted character.  To combat this, a single character check digit is often used with messages of fewer than 10 digits and a two character check digit being used for longer messages.  In the preceding examples, the last digit (8) is actually the computed check digit for the data message (4321).

While developed as a high-density, numeric barcode, but because of its poor reliability, Code 11 is not widely used.  Code 11 is primarily used in the labeling of telecommunications equipment.

How do we help developers using Code 11?

The Cognex Mobile  Barcode Scanner SDK supports Code 11 detection, enabling developers to gather relevant workflow and application data. You can download the SDK for free by registering on the Cognex Mobile Barcode Developer Network. In addition, the Barcode Scanner SDK supports a broad range of symbologies to meet your growing development needs.

Barcode Scanner SDK Features and Capabilities

Developing practical applications is challenging. That’s why we've developed a straight-forward barcode scanner software development kit (SDK) that boasts the most powerful scanning experience available for integration. It offers developers a simple, flexible, dynamic decoding experience, while still allowing for maximum control and flexibility over the user experience (UX). The Cognex Mobile Barcode Scanner SDK was built BY developers FOR developers... with the goal of making all your applications practical.

As a tool developed with the retail, manufacturing, government, healthcare, commercial services, and transportation industries in mind, our scanning solutions are built around efficiency for the end-user, as well as simplicity for the application developer. We understand that the enterprise is continually looking for opportunities to increase efficiency. Therefore, we have developed the ultimate single-handed scanning solution aimed at maximizing every promise of a return on investment.
