FAQ

Are the codes permanent?

Yes. The codes generated here contain the data directly (static codes). They do not expire and do not rely on any external redirection service.

What data is collected?

None. Both generation and scanning happen entirely within your browser using JavaScript libraries. We do not store your data or images.

Which barcode format should I use?

CODE128 is the most versatile and supports letters and numbers. For retail products, use EAN13 or UPC.
