How it works

Interleaved 2 of 5 encodes pairs of digits by alternating wide and narrow bars for one digit with spaces for the next, surrounded by start and stop patterns. The symbol is numeric and normally uses an even digit count, with an optional check digit supplied by the application.

  • Pairing digits makes the symbol compact for logistics labels.

Worked example

Input
											Digits: 12345678

Show text: true
Add check digit: false
Output

When to use this

Warehouse cartons, shipping labels, and scanner tests generate ITF symbols.

Edge cases

  • An odd number of digits needs padding or an application rule.
  • Quiet zones are required around the symbol for reliable scanning.
  • ITF-14’s check digit is not arbitrary payload validation.
