Frequently Asked Questions
Is GeraCode really free?
Yes. All GeraCode tools are 100% free, with no usage limits and no signup required.
Does it work on my phone?
Yes. GeraCode works on any device with a modern browser — desktop, tablet or mobile.
Is my data stored anywhere?
No. Everything is processed locally in your browser. Your generation history is saved only in your device's local storage and is never sent to a server.
What's the difference between a SKU and a barcode?
A SKU is an internal code you define yourself to organize inventory. A barcode (like EAN-13 or UPC-A) follows a public standard so any scanner or retailer system can read it.
