KitchenAid says the model number for its stand mixers can be found on the bottom and back of every mixer. The model number is a series of letters and numbers.
Every KitchenAid stand mixer has a white label that contains the serial and model numbers. The model number is for registering the appliance and ordering replacement parts should the need arise. Also, since there are different kinds of stand mixers, the model number helps owners find compatible attachments and accessories. The Contact Us page on the company's website has a helpful link that makes it easy to find the model number on any KitchenAid appliance.
