What Is the Dun-14 Barcode Symbology?

Description

The Dun-14 Barcode Symbology Grouped bar and space patterns used to represent different characters, designed to meet the needs of a specific application or industry. Refer to the advanced bar code symbologies that are supported by Loftware that include PDF 417, Maxicode, MicroPDF, Datamatrix, PostNet, QR, TLC39, and GS1 Symbologies. is based in the symbology Interleaved 2 of 5 (ITF) and it is a system for identifying containers. The format for the data is explained below.

Solution

• The code is 14 digits long and and includes the identifier for the type of container (the Packaging Indicator) and the UPC or EAN product code.
• In the case of a UPC code, a zero is added to the beginning of the manufacturer number to provide 12 digits, compatible with the EAN numbering.
• The check digit is calculated using the "modulo 10".
• The format is as follows for the data: 1001234567890 Type of container =1
• UPC Code of the product = 01234567890 (11 digits - without check digit)
• Final number = 1001234567890 X

The check digit (X) is the first position from right to the left. From the right:

1. Add up the numbers in the even positions (2,4,6,8,10,12 and 14). 0 + 8 + 6 + 4 + 2 + 0 + 1 = 21
2. Multiply by 3. (21 x 3 = 63)
3. Add the numbers in the odd positions (3,5,7,9,11, and 13) 9 + 7 + 5 + 3 + 1 + 0 = 25
4. Add with the result of the multiplication: 25 + 63 = 88
5. Round up to nearest multiple of ten: 88 + X = 90

The Check Digit A digit or character calculated from the data and appended as part of the data string to insure that the data is correctly composed and transmitted. is the number to reach the multiple of ten: X = 2
The final number is: 10012345678902
