ITF (Interleaved-2-of-5)
Interleaved-2-of-5 is a variable-length linear symbology that is used primarily in logistics and retail and encodes an even number of numerical characters.
A sample Interleaved-2-of-5 barcode is shown below.

ITF-14
ITF-14 is a GS1 subset of Interleaved-2-of-5 which encodes a GTIN-14.
The sample barcode below encodes a 14-digit GTIN and shows the horizontal and vertical bearer bars surrounding the barcode that are required for ITF-14.
If you are scanning ITF-14 barcodes exclusively, set the minimum and maximum length to 14 to avoid short scans.
