Interleaved2 of 5 barcodes
Interleaved 2 of 5 barcodes are used to label packaging materials across the globe. Since they can deal with high printing tolerances, they are ideal for printing on corrugated cardboard. ITF barcodes encode 14 numeric digits and use the full ASCII set.
One of the greatest strengths of Interleaved 2 of 5 is that its printed tolerances are suited for corrugated cardboard. As a result, this self-checking code is a powerful tool for encoding information on product packaging. While the Interleaved 2 of 5 barcode can only encode numbers (not letters), it does not require a check digit.
Common variants and structures: ITF-14, container number barcode (DUN-14)
Applicable industries: civil aviation, logistics industry, outer box packaging
ITF-14, SCC-14
The ITF-14 barcode is used to create the Shipping Container Symbol. This code is used to mark cartons and palettes that are including goods with an EAN-13 code. One digit is added in front of the EAN-13 code to mark the packing variant.
- The first digit is the “Logistic Variant”, also named as “Packaging indicator”.
- The next 12 digits are representing the product number. General this the EAN-13 number without the check digit.
- The last digit is the check digit. ActiveBarcode calculates this digit automatically.
The name ITF-14 is a composition of the barcode symbol used: “Interleaved 2 of 5” (Code 25 Interleaved) and the 14 digits: the length of the container symbol. ITF is an abbreviation of “Interleaved Two of Five”
DUN-14 code
The DUN-14 (Distribution Unit Number) is not really a barcode type. It’s a numbering system for shipping containers that uses other barcode symbology. The DUN-14 uses the ITF-14 or the EAN-14 symbol set. Modern installations always use the EAN-14 to encode the DUN-14.
The DUN-14 has the following data encoded:
- The first digits represents the number of units in the container: 1=6 units, 2=10 units, 3=12 units, 4=20 units, 5=24 units. The digits 6,7 and 8 are standing for other numbers of units.
- The next 12 digits are representing the product number. General this the EAN-13 number without the check digit.
- The last digit is the check digit. ActiveBarcode calculates this digit automatically.
