Frequently Asked Questions

Are the generated barcodes free for commercial use?expand_more

Yes, all barcodes generated via UtilVox are entirely free for personal and commercial use. No licensing restrictions on output.

How many barcodes can I generate in bulk?expand_more

There is no hard limit — you can generate hundreds at once. For very large batches (500+) we recommend splitting into groups to keep the browser responsive.

Which format should I use for retail products?expand_more

For international retail, EAN-13 is the standard. For North American markets, UPC-A is preferred.

Can I customize the barcode colors?expand_more

Absolutely. Use the color pickers to set any foreground and background hex. Ensure high contrast for reliable scanning.

The Right Barcode for the Job

Formats and where they belong

Barcodes aren't interchangeable — scanners and systems expect specific formats:

Format	Encodes	Used for
EAN-13	13 digits	Retail products worldwide (what stores scan)
UPC-A	12 digits	Retail in North America
Code 128	Full ASCII text	Logistics, internal inventory, shipping labels
Code 39	Uppercase + digits	Older industrial and ID systems
ITF-14	14 digits	Carton/case marking

Print rules that decide whether it scans

Scanners need contrast and breathing room: dark bars on a light background (never inverted, never on busy patterns), the quiet zone — blank margin on both sides — preserved, and size respected. Shrinking a barcode below ~80% of nominal makes cheap scanners unreliable; stretching only the width breaks the bar-ratio math entirely. Print one test label and scan it with the cheapest scanner you own before printing five hundred — the expensive scanner forgives flaws the cheap one won't.

Barcode or QR?

Barcodes hold a code; QR codes hold content. Inventory IDs, retail SKUs and anything scanned by existing barcode infrastructure stays 1D. Anything a phone scans — links, WhatsApp contacts, WiFi logins — wants the QR generator instead. To decode an existing label and see what's in it, the barcode reader works from your camera or an image, and product codes destined for invoices pair naturally with the invoice generator.
