FAQ
Where do I get a UPC number?
From GS1 or a number you already own. This tool only draws the bars for digits you paste.
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=UPC&value=SKU-1001. Spaces in the value show as %20 in the link. No signup.
