Frequently asked questions
- Is my barcode data uploaded?
- No. The barcode is drawn in your browser, so what you type never leaves your device. Only anonymous usage counts such as the barcode type are recorded, never the data.
- Which barcode types can I create?
- Code 128 for any ASCII text (labels, shipping and inventory codes), EAN-13 for retail products and UPC-A for products sold in North America. Other types such as EAN-8 or ITF are not included.
- What is the check digit and do I have to type it?
- EAN-13 and UPC-A end with a check digit that scanners use to catch misreads. Enter 12 digits for EAN-13 or 11 for UPC-A and the tool adds it. If you enter the full number and the last digit is wrong, it tells you which digit it should be.
- Can I use these barcodes on products in shops?
- The tool draws a valid symbol for the number you give it, but retail numbers are issued by GS1. Using a made-up number can clash with a real product, so get your company prefix from GS1 before selling with EAN-13 or UPC-A. Code 128 needs no registration for internal use.
- Should I download SVG or PNG?
- SVG is vector, so it stays sharp at any print size and opens in design tools. PNG is a plain image for documents and web pages; pick a wider module (3x or 4x) for a sharper print. Always test-scan the printed result.
