Frequently Asked Questions
Everything you need to know about inventory barcode generator online tool
Which barcode format is best for inventory management?
Code 128 is ideal for inventory because it supports alphanumeric data — letting you encode SKU codes like 'RM-COTTON-50KG' or bin locations like 'A-12-3' that purely numeric formats cannot. For retail products that also go through a POS, use EAN-13.
Can I generate barcodes in bulk for my inventory?
Yes. Upload a CSV or Excel file with all your product names and SKU numbers to Labeliy's bulk label generator to generate labels for hundreds of items at once — no manual entry for each product.
Do I need a barcode scanner to use these barcodes?
No dedicated scanner is required to get started. Any smartphone camera can scan barcodes using free apps. For regular warehouse or shop use, a USB wired barcode scanner (₹1,000–2,000) is significantly faster and more reliable.
What is a bin barcode and how is it different from a product barcode?
A bin barcode identifies a storage location (shelf, rack, or bin) rather than a product. When a staff member scans the bin barcode followed by the product barcode, the inventory system records that this product is at this location. This makes put-away, picking, and stock counting much faster.
Can I track inventory using only barcodes and a spreadsheet?
Yes. Even without dedicated inventory software, you can maintain a simple Google Sheet or Excel log: scan a barcode and record movements in/out. This basic system works well for small operations before investing in full inventory management software.
How do I handle products with multiple variants in inventory?
Assign each unique variant (size, color, flavor, pack size) its own unique barcode. All variants of the same parent product share a product family code in the first digits, with the remaining digits distinguishing the variant — this keeps your inventory SKU structure organized.
Who Is This For
When you manage stock in a godown, backroom, or small warehouse, the real problem is not knowing what is where until you physically open boxes. This page helps you generate barcodes for SKUs, locations, and batches so you can update inventory with a single scan instead of manually recording every movement.
For operations managers, storekeepers, and founders who want to move away from manual notebooks to a barcode-first inventory system, barcodes are the foundation. Every product gets its own barcode. Every bin or shelf gets a location barcode. When stock moves, staff scan the location and product codes — the system records the movement automatically. This creates an accurate, real-time picture of stock levels without end-of-day manual counts.
Once every SKU has a barcode, integrating with virtually any inventory management app or ERP becomes straightforward — the barcode is the universal key that connects physical stock to digital records. Use Labeliy's bulk label generator to print all your inventory barcodes in one session from a spreadsheet, and the label maker to create bin labels that clearly show both the barcode and the human-readable location code.
Why You Need Barcodes
- Barcoded SKUs and locations make stock counting dramatically faster — teams walk aisles with a scanner instead of ticking paper lists.
- They cut picking mistakes when multiple variants look similar, especially in high-volume dispatch operations.
- Once every SKU has a barcode, you can integrate with almost any inventory app or ERP later without relabeling.
- Barcode-driven stock movements create an automatic audit trail for inventory reconciliation and loss investigation.
Step by Step
- 1Decide on a unified coding format for SKUs and locations (for example, 'SKU-0001' for products and 'R01-B03-S02' for rack, bay, and shelf).
- 2Use the generator to create barcodes for each SKU and location code, using Code 128 for alphanumeric codes.
- 3Print and stick location barcodes on rack fronts and bin edges, and SKU barcodes on carton faces or product labels.
- 4Train your team to scan location first, then SKU, whenever they put stock away or pick items for an order.
Pro Tip
Add simple human-readable text below every barcode — the SKU code and location name — so even if a scanner fails or runs out of battery, your staff can still read and confirm the code visually without stopping work.
