Marking identifying the production batch of the product. It makes it easier to trace the origin and report a specific package. It is not an EAN code or expiration date, although the manufacturer may use a record containing a date element.
Linking a product to a manufacturing run
The batch number is used to identify a specific product batch. It is useful in contacts with the manufacturer, quality reports and determining the scope of a possible recall. It can be in the form of numbers, letters or a combination of both. It is not the same as the expiration date, although both markings are sometimes printed next to each other. If the print is illegible, it is worth keeping a photo of the packaging and proof of purchase. A similar batch number alone does not allow the full recipe to be recognized without the manufacturer's data.
The same product may have multiple batches with different production dates. The number is not a customer code or an individual serial number for each item. When reporting, it is worth copying it carefully and attaching a photo of the print, because similar characters can be easily confused when read manually.
Meaning and application
The batch number allows you to indicate a specific batch of the product when contacting the seller or manufacturer. It is not the same as date, EAN or SKU. Upon receipt, it is worth checking whether the markings on the packaging are legible.
In practice
Take a photo of the name, batch code, due date and list of ingredients, especially if you are throwing away the carton. Store the information with your purchase details. When reporting a problem, the product description and batch number will make it easier to identify the correct item.
Do not read the production date from the batch number according to the online pattern for another brand. Marking systems may vary. The mere existence of a code does not prove the product is authentic or meets the expected specifications.
