Label

A label is a physical identifier attached to an item, container, shelf, bin, pallet, or asset to support identification, counting, traceability, and location control in supply chain and manufacturing. It typically carries human-readable text and machine-readable data such as barcodes, SKU numbers, serial numbers, lot numbers, quantities, and storage locations. Labels serve as scannable source of truth for receiving, putaway, picking, replenishment, and cycle counting.

In a typical manufacturing operation, label generation begins when a SKU is created or a purchase order arrives. Warehouse staff print barcode labels from the WMS, apply them to incoming cartons or totes, and place items into bin locations identified by shelf labels. Every subsequent transaction—receiving, putaway, picking, issue to production, or cycle count—starts with scanning the item label, then the location label when stock moves. This scan-based process replaces manual data entry and keeps inventory quantities synchronized. On the shop floor, color-coded labels help workers visually separate raw materials, WIP, finished goods, tools, and equipment, reducing the chance of grabbing the wrong part. For lot-controlled materials, the label carries batch and quality status so expired or nonconforming stock can be quarantined before reaching production. Label durability matters; labels must stay readable through dust, moisture, and handling until the material is consumed.
