Keep dark bars on a light background. Red or light bars often won't scan.

How to build an ITF-14 number

  1. Take your product's GTIN without the check digit, e.g. UPC 036000291452.
  2. Put an indicator digit in front for the packaging level: 1 for a case of 12, 2 for a case of 24, and so on (you choose 1–8).
  3. Pad with zeros to 13 digits: 1 + 0 + 03600029145 → 1003600029145.
  4. Enter those 13 digits above and we add the check digit.

Each packaging level (single unit, inner pack, case) needs its own GTIN so warehouse systems know how many units are inside.

Frequently asked questions

What is an ITF-14 barcode used for?

ITF-14 marks outer cases and shipping cartons that hold several units of a product. It encodes a 14-digit GTIN and prints well on corrugated cardboard.

How do I get the ITF-14 number for a case?

Start with the product's 12-digit UPC or 13-digit EAN without its check digit, add an indicator digit (1–8) at the front to show the packaging level, pad to 13 digits, then calculate a new check digit. Enter the 13 digits here and we'll add it.

What is the bearer bar?

ITF-14 symbols are often printed with a thick frame or top and bottom bars, called bearer bars, so a scanner can't misread a partial scan. Many printers add these when printing directly on cartons.
