Questions, corrections, and symbology suggestions are all welcome.

General support

No monitored public support inbox is configured for this deployment. The owner must set PUBLIC_CONTACT_EMAIL before treating this page—or the site's legal disclosures—as production-ready.

Operator and privacy contact

The legal operator name and public operator address have not both been configured. Until they are, see the production warning above rather than assuming the publisher brand is the legal entity that operates the site.

No monitored privacy-contact address is configured for this deployment.

Reporting a barcode issue

To help us reproduce and fix a suspected problem quickly, please include:

• The generator you were using (for example, "EAN-13") and the exact input you typed
• What the tool said — the check-digit readout, any validation message, or an error
• If a downloaded barcode failed to scan: whether it was the SVG, PNG, or PDF, the printed size, and the scanner or app that rejected it
• Your browser and version, if the problem looks like a rendering issue

Confirmed issues are corrected in the verification layer and covered by a new automated test so they cannot recur silently. See the methodology page for how the check-digit layer and the renderer are kept honest. Because barcodes are generated entirely in your browser and your inputs never reach us, we cannot see what you typed unless you include it.

What we cannot help with

BarcodesGenerator cannot assign or license GS1 numbers — retail barcode numbers (EAN/UPC) come from GS1, and ISBNs come from your national ISBN agency. We also cannot certify that a printed barcode will scan on specific hardware; always test with your own scanner before production use.
