Abstract

Lot identification codes marked on packaging comprise a fixed number of digits with substrings representing each of a date, a SKU, a lot number, and optionally a line and a checksum. The same fixed number of digits is used for the lot identification codes employed by multiple producers across an industry, or across multiple industries. The lot identification codes are therefore readily recognizable by search engines and otherwise reduce the number of steps required for consumers and others along the supply chain to obtain lot-specific information about packaged goods. Additionally, whenever an individual submits a lot identification code, it provides an opportunity to collect information about the product at that point along the supply chain. The information can link the quality of the product at the time and place of the request to the time and place of the packaging.
