⚠ About retail barcodes (read this)

This tool creates barcode artwork for numbers you already own or use internally. It can't issue a registered, retailer-valid GTIN — those are licensed from GS1. If your product is going on store shelves or a marketplace, get the number from GS1 first, then design the barcode here for free.
