Buyer questions
Questions buyers actually ask
What is a cosmetic batch code?
A cosmetic batch code, also called a lot number, batch number, or production code, is a unique alphanumeric code stamped on a product by its manufacturer. It can help identify when and where that product batch was made.
Where can I find the batch code on my cosmetic product?
Look on the bottom or base of bottles and jars, the crimped end of tubes, the sides or base of an outer box, and occasionally on a label or seal.
What is the difference between a barcode and a batch code?
A barcode identifies a product for checkout and inventory, while a batch code identifies a production batch and is used to investigate when a cosmetic product was made.
What does the PAO symbol mean?
The PAO, or Period After Opening, symbol looks like an open jar with a number and M, such as 12M or 6M. It indicates how many months a product is intended to remain suitable after opening.
