Lot codes for CloroxPro and Clorox Healthcare products are printed on packaging and provide information on the location and date of production. They will appear either as a letter and a number, or two letters, followed by a series of numbers. Only the first seven characters are needed to know the location and date of production.
For example, the lot code A520064 is read as follows:
The first two characters — A5 — are the code for the production facility. The third and fourth characters — 20 — are numbers that indicate the year of production, in this case 2020. The fifth, sixth and seventh characters — 064 — are numbers that indicate the day of production according to the Julian calendar. In this case the 064th day of 2020 was March 4.
The production date was March 4, 2020.
Any additional characters or numbers after the first seven relate to other information such as time of manufacture, manufacturing line and may include the EPA code for the manufacturing location.
