Knowing how to find Moen faucet model number is the fastest way to order the correct cartridge, aerator or handle. Moen stamps its model information in a few predictable places, and you can usually read it without removing the faucet from the sink. This guide shows where to look, what the codes mean, and what to do when the number is worn off.

Check the Base of the Faucet First

Start under the sink. Most Moen kitchen faucets have a model number printed on the mounting base or on a label attached to the supply lines. Shine a flashlight up into the cabinet and look at the metal body where the hot and cold lines connect. The number is often a short alphanumeric code, sometimes with a separate series number beside it.

If you see only a serial number or a date code, note it anyway. Moen uses those to identify production runs, and a parts specialist can match them to the correct model.

Look Inside the Spout and at the Cartridge

If the base label is missing or painted over, the cartridge is your next stop. The cartridge is the cylinder that controls water flow and temperature. Its top or side is usually stamped with a part number, which is more useful for ordering replacement parts than the faucet model itself.

  1. Turn off the water supply under the sink.
  2. Remove the handle cap and handle screw, then lift off the handle.
  3. Read the markings on the cartridge cap and body. Write down every line of text.
  4. Check the spout base or the underside of the spout for an additional model stamp.

Use the Original Packaging, Manual or Receipt

If you still have the box or installation instructions, the model number is almost always printed on the carton and on the first page of the manual. The receipt or online order confirmation may also list the model name, which you can match against Moen’s catalog.

Keep a photo of these details on your phone so you do not have to dig through paperwork again.

Match the Finish and Style When You Have No Markings

Sometimes every label is gone. In that case, describe the faucet by its type and features: single-handle or two-handle, pull-down or pull-out spray, high-arc or standard spout, and the finish, such as chrome, brushed nickel or matte black. Then compare photos with Moen’s current and discontinued product lines. This method is less precise than reading a model number, so confirm the match with a photo before you order parts.

Checklist: What to Have Ready

  • A flashlight and a phone camera for photos of labels
  • The faucet’s location (kitchen or bath, and which sink)
  • The cartridge or part you need to replace, if known
  • The original box, manual or order confirmation, if available

Common Mistakes to Avoid

  • Confusing the faucet’s model number with a part number. They are different, and parts are listed separately.
  • Reading a number from a similar faucet in the same kitchen. Sinks are often fitted with different models.
  • Scrubbing the base label, which can rub off the text entirely.
  • Ordering a cartridge before confirming the cartridge code, since some models share a body but use different internals.

FAQ

Is the model number the same as the part number?

No. The model number identifies the whole faucet, while part numbers identify individual components such as cartridges, aerators and handles. You usually need both when ordering replacements.

Where is the model number on a Moen faucet that is already installed?

Most often it is on the mounting base under the sink or on a label near the supply lines. The cartridge and spout base may also carry markings.

What if I cannot read any number at all?

Take clear photos of the faucet, the cartridge and any visible text, then compare them with Moen’s product catalog or contact a plumbing supply store. A licensed plumber can also confirm the model before you buy parts.

Conclusion

Start with the base under the sink, then check the cartridge and any original paperwork. Writing down every code you find makes matching parts much easier. If the numbers are unreadable, a clear set of photos and a description of the faucet will usually get you close enough to order with confidence.
