KitchenAid Mixer Model and Serial Numbers Explained

Model Number: Provides general information related to the model and color

Serial Number: Provides details about your machine, like where it was made and in which year.

Model Number

KitchenAid’s model numbers offer insights into the specifics of their mixers, whether it’s a stand mixer or a hand mixer, the size of the bowl, and the color. Stand mixers typically have model numbers beginning with ‘KSM’ or just ‘K,’ indicating ‘KitchenAid Stand Mixer’ or ‘KitchenAid,’ respectively. The prefix may vary based on the manufacturing date and the country of use. On the other hand, ‘KHM’ denotes a hand mixer.

Following the prefix, a number usually indicates the bowl’s capacity in quarts. The trailing letters represent the color of the mixer. For instance, a stand mixer model number like K45SSOB signifies ‘KitchenAid, 4.5-quart, Stainless Steel, Onyx Black’. Similarly, KSM155GBCAR implies ‘KitchenAid Stand Mixer, 5-quart, Glass Bowl, Candy Apple Red’.

Sometimes, you might find numbers in the middle of the model number that don’t seem to have an obvious meaning. KitchenAid includes these to distinguish between similar models.

Note that model numbers are not unique to individual appliances. Instead, they represent the model type and color, meaning multiple mixers of the same kind will share the same model number.

Serial Number

The serial number of a KitchenAid mixer, comprising nine digits, provides information about its manufacturing location and date. The initial four digits symbolize the factory code and production date. The remaining digits are distinctive identifier for your specific stand mixer.

Consider this KitchenAid stand mixer with serial number WJ3976683 as an example.

The first four digits: WJ39

This indicates that the stand mixer was manufactured in factory ‘W’ in the 39th week of 1999.

The ‘J’ represents the production year, with each alphabet letter representing a specific year. Thus, ‘J’ equals 1999, ‘K’ equals 2000, ‘L’ equals 2001, ‘M’ equals 2002, and so forth.

As stated earlier, the digits following the initial four don’t carry a specific meaning and are utilized internally by KitchenAid for tracking individual stand mixers.

Where Can I Locate the Mixture and Serial Number of a KitchenAid Mixer?

Your KitchenAid stand mixer’s model and serial number can typically be found on a sticker or engraved plate. The location can vary depending on the model of the mixer, but it’s usually located in one of the following places.

  • Bottom of the mixer: You will find the model and serial number on a sticker on the underside of the mixer’s base for most models.
  • Back of the mixer: On some models, you might find the number on the back.
  • Inside the tilt-head: If you have a tilt-head model, tilt the head back and look for the number on the shaft that connects the head to the base.

Make sure to note down both numbers. The model number usually starts with “K” followed by numbers and letters. The serial number will be a string of numbers and letters.

If you still have trouble finding it, refer to the user manual provided with the mixer, or reach out to KitchenAid’s customer support for assistance.

Final Words: How to find out the age of your KitchenAid Mixer?

To determine the age of your KitchenAid mixer, inspect the serial number, which reveals the factory and week of manufacture. Product manuals may also offer hints. If still uncertain, contact KitchenAid’s customer support with your model and serial numbers for precise information. Remember, these numbers are typically found on a sticker or plate on the mixer’s bottom, back, or inside the tilt-head.
