ITF‑14 (Interleaved 2 of 5) is a GS1‑standard symbology used to identify logistic units like boxes or pallets. It carries a 14‑digit number (identical to GTIN‑14): the first digit is a packaging indicator (1‑8), followed by the 12‑digit product GTIN, and the last digit is a modulo‑10 check digit. ITF‑14 is commonly printed directly on corrugated cardboard for easy warehouse scanning.
This tool is completely free and ideal for logistics managers, warehouse operators, and supply chain professionals.
ITF‑14 refers to the barcode symbology, while GTIN‑14 is the data encoded. This checker validates the data format – i.e., a valid GTIN‑14.
Per GS1 standards, indicator 1‑8 are for logistic unit levels; 9 is reserved for variable‑measure products, and 0 is not used in ITF‑14.
Same as EAN‑13: odd positions (from left) multiplied by 3, even positions by 1, sum them, then take the modulo‑10 complement.
