If you have a newer model, you can usually find your model number on the bottom of the pressure cooker or canner body. If it’s a very old model, the number can probably be found on a label attached to the top of the cover. Old units have model numbers like 40, 50, 204, 603, etc. Newer models usually start with 01/ or 02/ followed by letters like PA or PC and more letters and/or numbers. The most recent styles always have seven digit ( all numerical) model numbers starting with 01 or 02 (Example: 0136001).
Note: All Presto Pressure Cookers and Canners also have the number “409A” stamped on the bottom. This is not the model number! It is a number used to indicate the product’s listing by Underwriters Laboratories (UL). Do not enter this number. Continue to look for a number more like the ones described above.
