In the date code example, what does EXP stand for?

• A. Expiration date
• B. Experience date
• C. Export date
• D. Exposure date

Answer: (A)

Understanding date code abbreviations on packaging helps you assess safety and quality windows. EXP on a date code stands for Expiration date—the last day the product is guaranteed to be safe and effective. After this date, the manufacturer can no longer guarantee potency, safety, or full quality, so using the product is not recommended.

Other phrases aren’t used in standard date codes for labeling shelf life. Experience date isn’t a recognized term in labeling, export date would denote shipping origin timing rather than product safety, and exposure date isn’t a label used to indicate a product’s usable period. So EXP clearly points to the expiration date, marking the end of the product’s usable period.
