Frequently Asked Questions

Which barcode format should I use?

For retail product barcodes, use EAN-13 (international) or UPC-A (North America). For internal inventory labels and general data encoding, Code128 is the most versatile. Code39 works well for simple alphanumeric identifiers.

Can I generate a barcode for any text or number?

Yes — most formats (Code128, Code39) accept any combination of letters, numbers, and symbols. EAN-13 and UPC-A require numeric-only input of specific lengths following the respective standard.

What is the difference between a barcode and a QR code?

Traditional barcodes (1D) encode data in a series of parallel lines readable only horizontally. QR codes (2D) encode data in a grid of pixels readable in any orientation and can store significantly more data.
