How to find the year your Licefreee! was manufactured:
Starting mid-2021, we have modified the format of our lot numbers. The number you will want to look for is the section that dictates the year. The year will be the two digits following a letter in the lot number. An example is 19C21010 is manufactured in 2021 (19C21010). The month is not specified.
You can always contact us to find the specific month and year for any product.
