Code 128

code 128

Code 128 is a very high-density barcode symbology. It is used for alphanumeric or numeric-only barcodes. It can encode all 128 characters of ASCII.*

Code 128 is used as base symbology to generate EAN-128 and GS1-128 barcode symbols.

Labeljoy requires you to enter an alphanumeric text up to 48 characters long to generate the barcode. Enter the text in the text box.
The human readable text can be shown below the symbol, above it or hidden according to the setting specified in the Text combo box.

Text concatenation:
When an Code 128 barcode element is generated by concatenating fields or counters, the following rule applies:
- Text length must not exceed 48 characters.
When a value not complying with the above rule is found, the barcode is not displayed.

Also, all ASCII characters above 127 will be removed.

Code 128 with text above the symbol
Code 128 with hidden text
