Frequently Asked Questions
What is the difference between CODE128 and EAN-13?
CODE128 supports full ASCII alphanumeric characters and is the global standard for logistics, shipping labels, and inventory. EAN-13 is a 13-digit numeric format used globally for retail point-of-sale products.
Can modern smartphones scan these barcodes without a dedicated reader?
Yes. Most modern iOS and Android camera apps and retail inventory apps can scan CODE128, EAN-13, UPC-A, and CODE39 barcodes directly from a screen or printed label.
How do I ensure my barcode prints with high scannability?
Export your barcode as scalable vector SVG or high-resolution PNG at 300 DPI. Ensure high contrast (black bars on clean white background) with sufficient quiet zones on both sides.
