Lot number

Lot number is a code molded into the stem of the dispenser, similar to the injection mold code (IMC).

Information About Lot Number

Basic Information

The lot number can be found on the underside of the foot of many Pez dispensers. It is used to designate the exact placement in the mold where that particular stem was produced. It is usually a two-digit number or a letter followed by a number.

Variations

Some lot numbers are only a single digit.

Years Produced

Lot numbers started to appear around 1990.

Feet

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. Not all 4.9 dispensers have lot numbers.

Dispensers from China, Hungary and Slovenia have lot numbers.

Stems

All stem colors may have lot numbers
