Is the batch code the same as the barcode?

No. The barcode identifies the product (the same for every unit); the batch code identifies the production run (different between runs). Use the batch code for dates.

Can a batch code verify authenticity?

No. A valid-looking batch code only tells you the format is plausible. Counterfeiters copy real codes, so a batch code is not proof of authenticity.

What if my brand is not in the checker?

The tool covers 238 brands. Less common brands and regional lines may not be included yet — check the printed date on the packaging, or contact the brand.

Do all brands encode batch codes the same way?

No. Formats are brand- or manufacturer-specific, which is why a brand-by-brand rule library is required.

Is my data uploaded when I use the checker?

No. Decoding runs locally in your browser; nothing is sent to a server.
