ITF-14/SCC-1 barcodes are a variant of the Interleaved 2 of 5 symbology, and they’re also used to produce Shipping Container Symbols (SCCs). The name ITF-14 is a combination of the symbology type. The “I” stands for interleaved, the T for two, and the F for five. The number 14 represents the total number of digits in the barcode. This sets it apart from typical Interleaved 2 of 5 barcodes, which can be any length to encode the required information.
Unique to the ITF-14/SCC-1 format is the use of a “Bearer Bar.” This is a thick black border which completely encircles the barcode. This border is used to equalize printing plate pressure and improve the overall accuracy and readability of ITF-14/SCC-1 codes. These Bearer Bars are mandatory when available space makes their inclusion possible.
