Frequently Asked Questions

What is the difference between an SKU and a Barcode?
An SKU (Stock Keeping Unit) is a human-readable code you create to track inventory internally. A barcode is the machine-readable graphic of that code. This tool generates both.
Can I use these barcodes for Amazon or retail stores?
These are Code 39 barcodes, ideal for internal use (warehouses, personal stores). Major retailers and Amazon typically require UPC/EAN codes, which must be purchased from GS1.
Is there a limit to how many I can generate?
In Batch mode, you can generate sets of codes. Since processing is local, you can generate as many as your browser memory handles, typically thousands without issue.
