Select EAN13 and enter 12 digits for automatic check-digit generation, or 13 digits with a valid check digit. Generating an image does not assign a registered product identifier.
Use it for internal labels and test with your scanner before operational use.
CODE128 accepts ASCII text. EAN13 and UPC require numeric identifiers. CODE39 has a more limited uppercase character set. Invalid content is flagged before download.
Download the PNG, retain its white quiet zone, and test the printed barcode with your intended scanner.
