Overview

Expiration date: AI (17)

The GS1 Application Identifier (17) indicates that the GS1 Application Identifier data fields contain an expiration date. The expiration date is the date that determines the limit of consumption or use of a product/coupon. Its meaning is determined based on the trade item context (e.g., for food, the date will indicate the possibility of a direct health risk resulting from use of the product after the date, for pharmaceutical products, it will indicate the possibility of an indirect health risk resulting from the ineffectiveness of the product after the date). It is often referred to as “use by date” or “maximum durability date.”

Note: A retailer may use this to determine a date that after which, they will no longer merchandise the product. Currently, there are implementations of best before date which are interpreted in their processes as date to Sell By.

The structure is:

  • Year: the tens and units of the year (e.g., 2003 = 03), which is mandatory.

  • Month: the number of the month (e.g., January = 01), which is mandatory.

  • Day: the number of the day of the relevant month (e.g., second day = 02); if it is not necessary

to specify the day, the field must be filled with two zeros.

Note: When it is not necessary to specify the day (the Day field is filled with two zeros), the resultant data string SHALL be interpreted as the last day of the noted month including any adjustment for leap years (e.g., “130200” is “2013 February 28”, “160200” is “2016 February 29”, etc.).

Note: This element string can only specify dates ranging from 49 years in the past to 50 years in the future. Determination of the correct century is explained in section 7.12.

The data transmitted from the barcode reader means that the element string denoting a best before date has been captured. As this element string is an attribute of a trade item, it must be processed together with the GTIN of the trade item to which it relates.

When indicating this element string in the non-HRI text section of a barcode label, the following data title SHOULD be used (see also section 3.2): BEST BEFORE or BEST BY
