Check the product packaging for an expiration date, best-before date, or use-by date
Look on the bottom, back, cap, or seal of the item
Inspect the label for printed, stamped, or embossed date codes
Check the box, wrapper, or outer carton if the date is not on the product itself
Use the batch or lot number to verify the expiry date on the manufacturer’s website or with customer support
For food and medicine, look for terms like EXP, BB, MFG, or LOT near the date code
If the date is unclear, contact the seller or manufacturer with the product code and batch number
