upc-a, upc-e
The Universal Product Code (UPC) is a barcode symbology, that is widely used in North America, and in countries including the UK, Australia, and New Zealand for tracking trade items in stores.* Labeljoy requires you to enter 11 digits to generate the barcode.
Enter the 11 digits in the text box.
The 12th digit (or check digit) is automatically calculated.

To allow the use of UPC barcodes on smaller packages where a full 12-digit barcode may not fit, a 'zero-compressed' version of UPC was developed called UPC-E.* Activate the "Use UPC-E
when possible" check box to instruct Labeljoy to try to apply the compressing algorithm. |

Text concatenation:
When an UPC-A barcode element is generated by concatenating fields or counters, the following rules apply:
- For the main barcode, only the first 11 digits found will be considered.
- For the add on, a dash (-) separator is required followed by 2 or 5 digits.
When a value not complying with the above rules is found, the barcode is not displayed.
UPC-A symbols may need to display the human readable digits is specific grouping. Use the Text style combo box to specify alternative ways to display the text:
 |
 |
| UPC-A with then 5-5-2 text style applied | UPC-A with then 5-4-3 text style applied |
UPC-A and UPC-E barcodes can also encode 2 or 5 additional digits. Enter the additional digits in the right text box:
 |
 |
| UPC-A with a 2-digit add-on | UPC-E with a 5-digit add-on |
The human readable text can also be shown above the symbol or hidden according to the setting specified in the Text combo box:
 |
 |
| UPC-A with text above the symbol | UPC-A with hidden text |
