FAQ
- Which format should I use for a retail product?
- Most retail products use EAN-13 (13 digits) internationally or UPC (12 digits) in North America. Check the barcode printed on similar products to confirm which one your retailer expects.
- Why does it say the value is invalid?
- Each format has strict rules — EAN-13 needs exactly 12-13 digits, EAN-8 needs 7-8, and UPC needs 11-12. CODE128 and CODE39 accept general text and are more flexible.
- Will the barcode work when printed?
- Yes. Download it at a decent size (or as SVG for crisp printing at any size) and keep some margin around it — most barcode scanners read printed barcodes reliably.
