Interleaved 2 of 5 barcode generator
Digits only, even count. Common in warehousing and distribution.
Terms of use: this site only turns the data you type into a barcode; it does not create, verify, register or store that data, and nothing is sent to any server. The content you enter and the use of the generated barcodes are solely the user's responsibility, including the right to use GTIN/EAN numbers (licensed by GS1), the accuracy of the information and compliance with applicable law. Links with dangerous schemes and typical attack patterns (scripts, SQL injection) are blocked, but this does not replace your own checks. By using the generator you accept these terms.

Test every barcode before use. The user is solely responsible for the accuracy of the barcode.

Interleaved 2 of 5 specification
Interleaved 2 of 5 (ITF) is a high-density numeric barcode: each pair of digits is encoded together — the first in the bars and the second in the spaces. It is used in logistics, warehouses and in ITF-14.
Content: digits only, in an even count. If the count (including the check digit, when present) is odd, a leading zero is added.
Each digit has 5 elements, 2 of them wide (hence the name "2 of 5").
Optional check digit (modulo 10, weights 3 and 1).
Wide-to-narrow ratio: 3:1 by default, adjustable from 2:1 to 3:1.
Because it is prone to partial reads, configure the scanner for a fixed length when possible.
How to use
Type the content. To create several barcodes, put one per line.
Adjust size, height, margin and colors. The preview follows every change.
Download each barcode in the format you need, or all of them as a ZIP.
In PDF, SVG and AI the size is set by the module X — the width of the narrowest bar, in millimetres. The default for this symbology is 0.33 mm. PNG and JPG use the chosen pixel resolution. If your printer warns about ink spread, increase the bar width reduction.
