Frequently Asked Questions
Is this barcode generator free to use?
Yes. Every format is free, unlimited, and requires no signup or account.
Are the barcodes generated actually scannable?
Yes. Barcodes are rendered using the industry-standard JsBarcode library and follow each format's official encoding rules, so they scan correctly with standard barcode readers and phone cameras.
Is my data uploaded anywhere?
No. The barcode is generated entirely in your browser using JavaScript — the data you enter never leaves your device.
Which barcode format should I use?
Use CODE128 for general-purpose labeling since it accepts almost any character. For retail products, use EAN-13 (international) or UPC-A (US/Canada) — but note these require a valid, officially assigned product number to work at real checkout scanners; a random 12-13 digit number will scan but won't correspond to a real product.
Can I use these barcodes commercially?
Yes, the generated images are yours to use freely. Just make sure any retail barcode number (EAN/UPC) is one you're actually authorized to use for that product.
Why does my EAN-13 barcode fail to generate?
EAN-13 requires exactly 12 or 13 digits — no letters or symbols. If you enter 12 digits, the 13th check digit is calculated automatically; if you enter 13, it must already be a valid check digit or the barcode will be rejected as invalid.
