Disclaimer
The batch-code service helps decode and compare markings, but it should not be treated as the sole criterion for authenticity or origin.
About authenticity
A single code cannot prove authenticity with complete certainty. A final conclusion always requires several signals taken together.
About country and factory claims
Sales country, barcode, batch code, and manufacturing site are different entities. The service only shows conclusions that are supported by a decoder rule or a reliable code structure.
About examples shown on brand pages
Verified and negative examples are educational references. They help users understand the input logic, but they do not replace expert review of a specific item.
