Frequently Asked Questions
- Which barcode format should I use?
- EAN-13 for international retail products, UPC-A for US/Canada retail, Code 128 for shipping/logistics (most versatile), Code 39 for industrial use, ITF-14 for cartons/pallets. QR codes are best for URLs and marketing.
- What is a check digit?
- A check digit is the last digit of barcodes like EAN-13 and UPC-A. It's calculated from the other digits using a formula and helps scanners detect read errors. The tool calculates it automatically.
- What resolution do I need for printing?
- For reliable scanning, print barcodes at minimum 300 DPI. The minimum bar width should be 0.264mm (1 mil). Larger barcodes scan more reliably. Always test scan your printed barcodes before mass production.
- Can I generate barcodes for my own products?
- You can generate the barcode image, but EAN/UPC numbers must be officially assigned by GS1 (the global standards organization). Using unauthorized numbers can cause conflicts with other products. Code 128 and Code 39 have no registration requirement.
