Free barcode generator
Type a value, pick a symbology and download a print-ready barcode as PNG or vector SVG. CODE128 encodes any text, while EAN-13, EAN-8 and UPC-A are the retail product codes used on packaging worldwide.
Why is my EAN / UPC code invalid?
These formats require a fixed number of digits (EAN-13: 12 or 13, EAN-8: 7 or 8, UPC-A: 11 or 12). If you leave off the final check digit it is calculated automatically; if you include a wrong one, the code is rejected.
