Read the package before choosing a number
Start at the box flap and base, then inspect the bottle or jar bottom, tube crimp and label edges. Light angled across an embossed mark may make it easier to read.
Look for a lot or batch label where present. A manufacturing lot is different from a retail barcode, shade, size, product reference or shop sticker; position and length alone are not enough.
Keep box, bottle and kit components separate
If both box and container carry marks, read each with its surrounding label before deciding which is the production lot. A gift set can include separately marked products.
Do not concatenate two marks. Retain a photo or note of the original package so an unclear character can be checked without guessing.
- Photograph the lot with the surrounding label so you retain its package context.
- Copy one complete mark, including its leading zeroes and separators.
- Compare the typed lot against the photo before checking; do not substitute an order number for unreadable print.
Move from finding the lot to checking it
In the homepage checker, select the brand on the product and copy the full lot with letters, leading zeroes and separators. A lot number may include letters despite its name.
If the print is unreadable or the brand is absent, use the product's label and ask the brand with packaging details. A receipt or order number is not a substitute.
