There is a serial number on every pan. It is a very small 7 digit code, that starts with BY. You may require a magnifying glass to read it.
Location by type
- Pans & 12" Wok: lip (outside) across from the handle
- Pots w/one handle: underneath the lip (outside) across from handle
- Pots w/two handles & 14" Wok: underneath the lip (outside) in between handles
- Griddles: back of the handle
Here are some photo images to help you locate the serial number. For everything besides the griddle, remember to look on the outside of the pan/pot/wok, under the lip.
