Shiseido batch codes notice
February 20th, 2014

We got unverified notice saying Shiseido does not include production date information into the batch codes anymore. Instead, they generate unique character sequence for each batch, and record correlation between production date and such batch code into the databases. If this information is correct, it’s possible to identify manufacturing date of a product only having an access to the company internal databases.
As previously mentioned, this information is unconfirmed. We’re trying to clarify and verify it. Until this will happen, support for Shiseido has been removed. We’re sorry for inconvenience.
Please contact us if you have any information regarding Shiseido batch codes.
