What Is a Barcode Generator?
This tool generates a numeric barcode using the Interleaved 2 of 5 (ITF) symbology — a common, compact barcode format used for numeric codes like product identifiers, tracking numbers and inventory codes — rendered entirely in your browser as a downloadable image.
ITF encodes digits in pairs, using the width of bars and spaces to represent each digit, and is widely supported by barcode scanning hardware and apps for numeric-only use cases.
