MSI Plessey barcode generator
Used for inventory control and supermarket shelf labels. Digits only.
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.
Preview
PDF and AI are vector files in CMYK, with black as C0 M0 Y0 K100. PNG, JPG and SVG are RGB.
Test every barcode before use. The user is solely responsible for the accuracy of the barcode.
MSI Plessey specification
MSI Plessey (Modified Plessey) is used mainly on supermarket shelf labels and for inventory control.
Content: digits only. Each digit is encoded in 4 bits, each bit represented by a bar/space pair.
Checking: none, modulo 10, modulo 10/10, modulo 11 IBM (weights 2 to 7), modulo 11 NCR (weights 2 to 9), modulo 11/10 IBM or modulo 11/10 NCR. The default is modulo 10 — choose the same one configured in the scanner.
If modulo 11 results in 10, the barcode cannot be generated with that method; choose another.
Wide-to-narrow ratio: 2:1 by default, adjustable from 2:1 to 3:1.
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.
