Frequently Asked Questions
FAQs about Barcode Generator
Which barcode format should I use?
CODE128 is the most versatile (supports all ASCII characters). Use EAN-13 or UPC for retail products, CODE39 for industrial labels, and ITF-14 for shipping cartons.
Why does my barcode show an error?
Each format has specific input requirements. EAN-13 needs exactly 12-13 digits, UPC needs 11-12 digits. CODE128 accepts any ASCII text.
Can I use the output for commercial products?
The barcodes are standards-compliant, but for commercial use (retail UPC/EAN), you need to register with GS1 to get an official number range.
Why SVG instead of PNG?
SVG barcodes are vector graphics that print crisply at any size without pixelation. They are ideal for labels and packaging.
Is my data safe?
Yes. Barcodes are generated entirely in your browser using JsBarcode. No data is sent to any server.
