  • EAN-8 uses 7 body digits plus one check digit.
  • UPC-A uses 11 body digits plus one check digit.
  • Code 39 supports uppercase letters, numbers, spaces, and - . $ / + %.

Frequently asked questions

Can I use these barcodes for live retail products?expand_more

Use the output for drafts and tests. For retail distribution, confirm that the number was issued through GS1 or your authorized issuer.

Why is the quiet zone important?expand_more

Scanners need blank space before and after the bars. Keep the quiet zone generous when printing small labels.
