Generate Inventory Barcodes in Bulk — FreeWhy Barcode Inventory Systems Save Time and Reduce Errors
Manual inventory counting is slow and error-prone. A barcode inventory system lets staff scan items in seconds — receiving new stock, picking orders, doing stocktakes, and transferring goods between locations. Every scan updates your inventory count automatically, eliminating transcription errors and saving hours of manual work every week. Setting up a barcode system starts with generating the right labels: Code 128 for general-purpose item and location tracking, ITF-14 for outer cartons, and Code 39 for legacy systems that require alphanumeric codes. Our bulk generator lets you paste a spreadsheet column of SKUs and generate all labels in one click.

What is the best barcode format for warehouse inventory?
Code 128 is the most widely used format for warehouse inventory because it encodes both letters and numbers at high density, is readable by all modern barcode scanners, and produces compact labels. ITF-14 is used specifically for outer carton labels (case packs and pallets). Code 39 is an older format still used in legacy systems.
Can I generate barcodes for hundreds of SKUs at once?
Yes. Our bulk barcode generator lets you paste an entire column of SKUs (one per line) and generates all barcodes simultaneously. You can then download them all as a ZIP file containing individual PNG or SVG files, named by SKU for easy identification.
What label size should I use for warehouse shelves and bins?
For shelving and bin location labels, 2" × 1" or 3" × 1" labels are common. For pallet and carton labels, 4" × 6" is the standard shipping label size. Our SVG format scales to any size without quality loss, making it easy to print at any dimension.
Do I need special software to scan the barcodes I generate?
No. Barcodes generated by our tool follow international standards (GS1, ISO) and are readable by any barcode scanner or smartphone scanning app. Once scanned, the decoded text (your SKU or item number) appears in whatever system is connected to the scanner — your spreadsheet, ERP, WMS, or POS.
How do I create location barcodes for warehouse shelves?
Create a naming convention for your warehouse locations — for example, A-01-01 (Aisle A, Bay 01, Level 01). Enter each location code into our bulk generator and download labels for every shelf position. Scan a location barcode followed by a product barcode to record a put-away or pick event in your WMS.
What file format should I download for thermal label printing?
SVG is the best choice for thermal printers (Zebra, Honeywell, Dymo) because it is a vector format that scales without any quality loss. PNG at 300 DPI or higher is an alternative for standard laser or inkjet printers.
