Frequently Asked Questions About Barcodes & SKUs
Everything you need to know about tracking inventory and printing barcode stickers
What is a Code 128 barcode?
Code 128 is the high-density global standard for internal inventory management, shipping labels, and SKU tracking. It can encode all 128 ASCII characters (alphanumeric text, numbers, and dashes).
Can I print these on standard Avery sticker sheets?
Yes. When printing, select 100% scale in your browser print window. The output formats cleanly onto standard letter label sheets (such as Avery 5160 30-up labels) or 2"x1" direct thermal rolls.
What is the difference between a SKU and a UPC barcode?
A UPC (Universal Product Code) is a standardized 12-digit number purchased from GS1 for global retail. A SKU (Stock Keeping Unit) is your own internal alphanumeric tracking code (e.g. SHIRT-BLU-LG) used to track items in your personal warehouse or store.
Are barcode scanners compatible with these generated tags?
Yes. These render clean high-contrast SVG vectors that any handheld USB/Bluetooth laser or camera barcode scanner can read instantly.
