Frequently Asked Questions

Which barcode format should I use?

Use Code 128 for general purposes and inventory. Use EAN-13 or UPC-A for retail products (depending on your region). Use Code 39 for industrial or military applications.

Are these barcodes scannable?

Yes, the generated barcodes follow standard encoding patterns and should be scannable by most barcode readers. However, always test with your specific scanning equipment before mass production.

What resolution should I use for printing?

For best results, use the SVG format for print as it scales without quality loss. If using PNG, download at a larger size and ensure 300 DPI when printing.

Do I need to register my barcode?

For retail sales (EAN/UPC), you typically need to purchase GS1-registered barcodes. Code 128 and Code 39 can be used internally without registration.

Is my barcode data secure?

Yes. All barcode generation happens locally in your browser. Your data is never sent to or stored on our servers.
