❓ Frequently Asked Questions
Q: What is the difference between EAN‑13 and UPC‑A?
EAN‑13 is used internationally and has 13 digits (12 data + 1 check). UPC‑A is the North American standard with 12 digits (11 data + 1 check). Both are automatically calculated – just enter the first 12 (for EAN) or 11 (for UPC) digits and our generator adds the checksum.
Q: My barcode doesn’t scan. What could be wrong?
Ensure high contrast (dark lines on light background). Avoid very narrow widths (try width ≥2px). Also verify that the data format matches the symbology (e.g., EAN requires digits only). Our preview shows if the data is valid.
Q: Can I use these barcodes commercially?
Yes, the generated barcodes are royalty‑free. However, for retail products you may need to register your company prefix with GS1 to ensure uniqueness. This tool is for generating the graphical symbol only.
Q: Why download as SVG instead of PNG?
SVG is a vector format – it scales to any size without pixelation, perfect for printing on labels, boxes, or documents. You can also convert SVG to PNG/PDF using free tools if needed.
Q: Do you store my barcode data?
No. Everything runs in your browser (client‑side). We never see or store the numbers you enter.
