FAQ
Which format should I use?+
Code 128 for general-purpose text/mixed data; EAN-13 for retail products (Korea uses prefix 880); ISBN for books (EAN-13 with 978 prefix); EAN-8 for small items; UPC-A for US/Canada products; Code 39 for industrial/asset tags; ITF-14 for outer cartons.
Code 128 vs Code 39?+
Code 128 is denser and supports upper/lowercase letters and symbols. Code 39 is older and broadly compatible but takes more space. Use Code 128 for new systems.
Are checksums calculated automatically?+
Yes. EAN-13/EAN-8/UPC-A check digits are computed for you. Just enter 12 (EAN-13), 7 (EAN-8), or 11 (UPC-A) digits.
What is the minimum size for scanning?+
Code 128 needs ~2cm width; EAN-13 needs ~3cm to scan reliably. Larger if print quality is low.
Can I use Korean or non-ASCII characters?+
1D barcodes only support ASCII. Use QR codes for Korean or other non-ASCII text.
PNG or SVG?+
SVG for print (vector, infinite zoom). PNG is fine for screens.
Why no GS1-128 or similar standards?+
This tool generates plain Code 128. GS1-128 (with Application Identifiers) is a separate standard that needs a dedicated tool.
