Frequently Asked Questions
Everything you need to know about warehouse barcode generator online tool
What barcode format is best for warehouse use?
Code 128 is the industry standard for warehouse and logistics barcodes. It handles alphanumeric location codes (like 'A-12-3'), serial numbers, and any identifier that mixes letters, digits, and symbols — all at high data density in a compact symbol.
Can I label warehouse shelves and bins with these barcodes?
Yes. Generate location codes for each shelf, bin, or rack position and print on durable label stock. For harsh warehouse environments (cold stores, outdoor areas), use polyester or polypropylene labels rather than paper — they resist moisture, abrasion, and temperature extremes.
What is the best location code structure for warehouse barcodes?
A clear hierarchical structure works best: Zone-Aisle-Rack-Level-Bin (e.g., 'WH-A-R12-L3-B04'). Keep it short enough for quick scanning but descriptive enough for staff to read directly. Consistent structure makes it easy to train new team members.
How do warehouse location barcodes integrate with WMS software?
Most WMS platforms (SAP WM, Oracle, Logiwa, Fishbowl, Zoho Inventory, Increff) let you define location codes and link products to bins. Scanning a bin barcode followed by a product barcode records a put-away or pick event. The WMS updates stock position instantly.
Can I generate location barcodes in bulk for an entire warehouse?
Yes. Create a spreadsheet with one row per location — zone, aisle, rack, level, bin — and upload it to Labeliy's bulk label generator to produce all location labels in one print run. This is far faster than generating one at a time.
What label size works best for warehouse shelf and bin labels?
For bin and shelf labels, 100×50mm minimum is recommended so the barcode and human-readable location code are both large enough to read from a normal working height. For high racks where staff cannot scan from ground level, 150×75mm or larger ensures visibility.
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.
