Information About Lot Number
The lot number is used to designate the exact placement in the mold where that particular stem was produced. It can be found on the underside of the foot of many Pez dispensers.
The lot number is usually a two-part code, either a two digit number, a number followed by a letter or a letter followed by a number.
- Some lot numbers are only a single digit, either on the left or the right side of the foot.
- Some lot numbers are three digits.
- Some lot numbers include Roman numerals (I, IV, VI, VII, VIII)
Lot numbers started to appear around 1989.
Since lot numbers appear on the bottom of the dispenser's foot, only dispensers with feet have lot numbers.
Patents & Countries
Lot numbers began to appear on Pez dispensers with the 4.9 patent. However, not all 4.9 dispensers have lot numbers.
All stem colors may have lot numbers
