# What Is the Dun-14 Barcode Symbology?

## Description

The Dun-14 Barcode Symbology 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 is the number to reach the multiple of ten: X = 2
The final number is: 10012345678902
