Who Is This For
Warehouse teams juggle racks, bins, pallets, and cartons daily. Without a location barcode system, stock gets misplaced, picking errors happen, and stocktaking takes days. This page helps you generate robust Code 128 barcodes for location codes and product identifiers so your WMS — or even a simple spreadsheet — can track every stock movement with a single scan.
A complete warehouse barcode system has two layers: product barcodes that identify what an item is, and location barcodes that identify where it is stored. When staff scan the bin barcode before scanning the product barcode during put-away or picking, the system automatically records the movement. This dual-scan approach creates an accurate, real-time stock location map without manual data entry or clipboards.
For warehouse managers, 3PL providers, and operations leads who want to standardize labeling across shelves, zones, and pallets, the startup cost is minimal — generate location barcodes here, print on durable polyester labels with Labeliy's label maker, and mount them at consistent heights on shelf edges. A complete warehouse labeling setup for a 500-location facility can be done in a single day.
Why You Need Barcodes
- Location barcodes let pickers confirm they are at the correct rack or bin before picking, reducing costly mis-picks and mis-shipments.
- Pallet and carton barcodes make inbound and outbound scanning faster and more accurate, especially at busy dock doors.
- Consistent warehouse barcoding is a prerequisite for advanced workflows like wave picking, cycle counting, and FIFO management.
- Barcode-driven stock movements create an automatic movement audit trail, making it possible to trace exactly when and where a discrepancy occurred.
Step by Step
- 1Design a location code system that clearly represents zones, aisles, racks, levels, and bins (e.g. 'A01-R02-L3-B03' for zone A, rack 02, level 3, bin 03).
- 2Generate Code 128 barcodes for each location code and create a spreadsheet mapping every code to its physical location.
- 3Print large, high-contrast location labels (100×50mm minimum) and fix them at eye level on rack uprights and bin fronts.
- 4Train staff to always scan location barcode first, then product barcode, for every put-away and pick operation.
Pro Tip
Use oversized labels with both text and barcode on higher racks — pickers should be able to confirm their location visually from the ground while the scanner reads the code from the label. This dual-readability at height speeds up picking in multi-level rack systems.
