Code 11 barcode generator

Code 11 is a barcode symbology used mainly in telecommunications. It is developed by Intermec in 1977. The symbol can encode any length string (though Labeljoy limits it to 255 characters) consisting of the digits 0-9 and the dash character (-). One or two check digit(s) can be included.

How to generate Code 11 Barcode

Code 11 Barcode

code 11 symbol

Labeljoy requires you to enter a text in the text box of up to 255 characters.

Code 11 requires 1 or 2 check digits. The combo box Checksum enables you to define the number of check digits to be appended at the end. The selection (Auto) will add 1 check digit to texts of length up to 10 digits and 2 for longer texts, while the selections 1 and 2 will force 1 and 2 check digits respectively, regardless of text length.

With Labeljoy you can create and print Code 11 Barcode Labels in easy way.

Note: Check digits are only appended to the barcode symbol. They are not appended to the human readable text.

Text concatenation:
When a Code 11 barcode element is generated by concatenating fields or counters, the following rules apply:

  • The text can contain digits and dash (-) signs only.
  • Code length must not exceed 255 digits, including dash signs.

When a value not complying with the above rule is found, the barcode is not displayed.

The human readable text can also be shown above the symbol or hidden according to the setting specified in the Text combo box.
