When to use a CODE128 barcode generator
Pick CODE128 for warehouse, shipping, and in-house SKUs. It encodes letters and numbers in a compact width. It is not a GS1 company prefix. Retail checkout still wants UPC or EAN if the store POS expects those.

FAQ
Does CODE128 need a special font?
No. The app draws native bars. Do not paste a barcode font from Excel. Those often fail to scan on thermal printers.
Do I need an account?
No. Click Generate. The free label maker opens with your data already on the canvas. Work stays in this browser.
Can I open a label that is already filled in?
Yes. A link with the value already in it opens the maker with the barcode on the canvas. Example: https://app.mylabelmaker.com/?tool=barcode&format=CODE128&value=SKU-1001. Spaces in the value show as %20 in the link. No signup.
