Check the printed date on the packaging, label, bottle, jar, box, or wrapper
Look for terms such as “EXP,” “Expires,” “Best Before,” “Use By,” or “Sell By”
Check the bottom, back, cap, neck, or seam of the package for a stamped code
Read the product label or manufacturer instructions for date information
Use the batch or lot number and contact the manufacturer if no clear date is shown
Check the outer carton and inner container, since dates may appear in different places
For food, compare the date with storage conditions and packaging integrity
For cosmetics and personal care products, look for the PAO symbol or opening date marker
For medicines, check the blister pack, bottle, or box for the expiration date
If the date is missing or unclear, do not use the product until verified
