What is MSI Plessey?

The MSI barcode (also known as Modified Plessey) is a continuous, numeric-only symbology. It is not as common in retail, but it dominates in specific niche environments like grocery store shelf labeling and library inventory.

Advantages for Inventory

MSI is a low-density code, meaning it takes up more space to represent data compared to Code 128. However, this simplicity makes it very robust for simple numeric stock keeping units (SKUs) where alphanumeric characters are not needed. It is variable length, allowing you to encode as many numbers as your shelf tag allows.
