Your KitchenAid model number is the single most useful piece of information for figuring out which attachments, bowls, and parts will actually fit your mixer. It’s also the fastest way to tell exactly which mixer you own, since KitchenAid has sold dozens of variations across similar-looking product lines for decades.
Quick Answer: Look for a metal or paper sticker on the bottom of your mixer’s base, or on the back near where the head meets the body. The model number usually starts with a letter, most often K or KSM, followed by a series of numbers and letters that identify the bowl size, series, and color.
In this article, we’ll cover:
Where to Find the Model Number
Before you can decode your KitchenAid mixer model number, you first need to locate the identification label.
The exact location depends on your mixer design, but most KitchenAid stand mixers place the model information on the underside or near the base of the machine.
The exact placement varies slightly by mixer age and series, but it’s reliably in one of these spots:
Tilt-Head Mixers
Raise the mixer head and check underneath the motor housing or around the base area for the identification label.
Step 2: Look underneath
Bowl-Lift Mixers
Check the underside of the mixer base where the model and serial information is usually printed on a sticker.
Step 2: Inspect the base
Read The Label
Once located, identify the model number separately from the serial number before searching for parts.
Serial: XXXXXXXX
The sticker typically shows both the model number (labeled “MODEL NO.”) and the serial number (labeled “SERIAL NO.” or similar) together, but they serve different purposes, covered below.
How to Decode the Model Number
A KitchenAid model number is more than a random combination of letters and numbers. Each part identifies important details about your mixer, including the mixer family, series, design type, and colour or finish code. Understanding the model number helps you find compatible bowls, beaters, attachments, and replacement parts with confidence.
KitchenAid model numbers follow a consistent pattern, though the exact structure has changed slightly across different eras and series. Here’s how to read the most common format:
Example: KSM150PSER
Mixer Family
Identifies the KitchenAid stand mixer product family.
Model Series
Shows the specific mixer series and design group.
Product Variation
Identifies the specific configuration or production version.
Colour / Finish Code
Represents the finish or colour identifier.
- Prefix (K or KSM): Identifies the mixer as a KitchenAid product. KSM specifically stands for KitchenAid Stand Mixer.
- Number sequence: Usually indicates the bowl size. For example, “45” typically means 4.5 quarts, “5” or “150” typically means 5 quarts.
- Letter suffix: Usually indicates the color or finish. For example, suffixes like “OB” (Onyx Black) or “ER” (Empire Red) are common.
Example: A model number like KSM150PSER breaks down as: KSM (KitchenAid Stand Mixer), 150 (5-quart bowl, Artisan-style numbering), PSER (Empire Red).
A caution worth knowing: not every character in a model number carries meaning. KitchenAid sometimes adds extra digits or letters simply to distinguish otherwise identical models from one another, particularly for retailer-exclusive color variants. If part of your model number doesn’t match a pattern you recognize, that’s normal, and it doesn’t mean you’ve misread the sticker.
Model Number vs. Serial Number: They Answer Different Questions
It’s easy to look at the sticker and treat both numbers as the same kind of information, but they’re not.
Model Number vs Serial Number
Understand the difference between these two important KitchenAid identifiers.
Model Number
Identifies the specific KitchenAid mixer model you own.
- Used to find manuals
- Helps identify compatible parts
- Shows the mixer model series
Serial Number
Identifies your individual KitchenAid mixer unit.
- Unique to your appliance
- Helps identify production details
- Useful when contacting support
If your goal is checking whether an attachment or bowl will fit, the model number is what you need. If your goal is figuring out how old your mixer is or confirming warranty coverage, you’ll need the serial number instead, and in some cases, the exact date-decoding format has varied across manufacturing eras, so a mismatch between what you’d expect and what you see doesn’t necessarily mean an error.
Why This Matters for Compatibility
Nearly every practical question about your mixer, will this attachment fit, will this bowl work, what replacement part do I need, ultimately depends on knowing your exact model number rather than just “I have a KitchenAid” or even “I have an Artisan.” Two mixers that look identical on the outside can have different bowl sizes, different attachment hub generations, or different locking mechanisms depending on when and where they were made.
Why Your KitchenAid Model Number Matters for Compatibility
The correct model number helps you find information, parts, and accessories that match your mixer.
Correct Replacement Parts
Avoid ordering parts that do not fit your specific KitchenAid mixer model.
Compatible Accessories
Check your model before choosing bowls, beaters, and other mixer accessories.
Right Manuals & Guides
Your model number helps you locate the correct product manuals and support information.
Avoid Costly Mistakes
Confirming your model prevents buying parts or accessories made for another mixer.
Once you have your model number, you can use it directly with:

Pro Tips
- Photograph the sticker once and keep it somewhere accessible. The sticker can wear or become hard to read over years of use, so having a photo saved means you’re not turning the mixer over every time you need the number.
- Search using the exact model number, not the series name. Searching “KSM150PSER” gets you far more precise results than searching “KitchenAid Artisan,” since the series name alone doesn’t specify bowl size or generation.
- Don’t assume two mixers in the same series match. The Artisan line, for example, has been sold with several different bowl sizes and hub generations over the years, so relying on the series name alone can lead to buying an incompatible part or attachment.
Frequently Ask Questions
Can I find my mixer manual using the model number
Yes. Your model number helps match your mixer with correct documentations
Where can I find my KitchenAid model number?
The model number is usually located on the identification label attached to your mixer.
What if I can’t find a sticker anywhere on my mixer?
Check the original packaging or manual first, since the number is often printed there as well. If neither is available, KitchenAid’s customer support can often help identify a model based on photos and visible features, though this is less precise than reading the sticker directly.
Does the model number tell me how old my mixer is?
Not directly. The model number identifies the series, bowl size, and color, while the serial number is what indicates manufacturing date, though the exact decoding format has varied over the mixer’s long production history.
Can I use a model number from an old mixer to check current attachment compatibility?
Yes, this is exactly what the model number is for. Since compatibility is tied to the mixer’s specific design rather than how recently it was purchased, an older model number is just as useful for checking compatibility as a current one.
Why do I need my KitchenAid model number?
It helps you find compatible parts, accessories, manuals, and support information.
Final Thoughts about KitchenAid Model Number
Your model number is the starting point for nearly every other compatibility question you’ll have about your mixer.
Finding it takes a minute, and decoding the basics, series, bowl size, and color, takes only slightly longer.
Once you have it, hold onto it, since you’ll likely need it again the next time you’re checking whether a new attachment, bowl, or replacement part will actually fit.
