Frequently Asked Questions

Is this barcode generator free to use?

Yes, completely free! Generate unlimited barcodes without registration. All barcodes are created in your browser with no data sent to servers.

What barcode format should I use?

Code 128 is recommended for general use - it's compact, supports letters and numbers, and is widely compatible. Use EAN-13 for retail products sold internationally, or UPC-A for US retail. Code 39 is common in industrial settings.

Can I use these barcodes commercially?

Yes! Barcodes generated here can be used for any purpose including commercial products, inventory management, and shipping labels. However, for retail products, you may need to register with GS1 to get official EAN/UPC numbers.

Why won't my barcode generate?

Each barcode type has specific requirements. EAN-13 needs exactly 12 or 13 digits. UPC-A needs 11 or 12 digits. Code 39 only supports uppercase letters, numbers, and some symbols. Code 128 is the most flexible and accepts any text.

Do the generated barcodes work with scanners?

Yes! All barcodes are generated to industry standards and work with standard barcode scanners. For best results, ensure adequate size (at least 1 inch wide for most formats) and good contrast between bars and background.
