This generator supports printable ASCII with automatic code-set selection. It is not a GS1-128 application-identifier encoder.
Common questions
Does this register my barcode?
No. Creating artwork does not assign or register a GS1 identification number.
Can I enter a value without the check digit?
EAN-13, EAN-8, UPC-A, and ITF-14 accept their data digits and calculate the final check digit. A supplied invalid check digit is rejected.
Which format should I print?
SVG is scalable artwork; PDF preserves the chosen physical width. Print at actual size, without fit-to-page scaling.
