How to Find Your Moen Bathroom Faucet Model Number: Quick & Easy Guide

Logan Jun 01, 2026

Finding the correct model number for your Moen bathroom faucet is the first step to unlocking a world of effortless repairs, genuine replacement parts, and seamless maintenance. Whether you are dealing with a slow drip or planning a stylish upgrade, that specific string of characters is your key to compatibility. This guide walks you through the most reliable methods to locate this identifier, saving you time and frustration.

Why the Model Number Matters

Before diving into the search, it is important to understand why this small code is so significant. Moen produces hundreds of faucet styles, and while many look similar visually, the internal components—such as valves, cartridges, and trim kits—are often model-specific. Using the wrong parts based on an inaccurate identifier will lead to frustration and wasted effort. Having the exact number ensures you purchase the correct repair kit or replacement handle, guaranteeing a proper fit and optimal function.

Check the Packaging and Original Documentation

If you still have the original box or purchase receipt, you are in the ideal situation. Manufacturers typically print the model number prominently on the barcode label or the side of the packaging. Look for a sequence of letters and numbers, often preceded by the letter "M" or formatted as "76##" or "86##". If you have the product's warranty registration or original instruction manual, the model identifier is usually listed on the first page alongside the serial number.

Locating the Stamped Identifier

When the original packaging is long gone, the fixture itself holds the answer. The most reliable method is to inspect the underside of the faucet handle or the base of the spout. Manufacturers stamp or engrave the model number directly onto the metal body. You will likely find a plaque or a series of small characters positioned in a spot that requires a flashlight and a quick peek to see clearly.

How to Inspect the Fixture Base

For wall-mounted or deck-mounted faucets, you might need to remove the handle cap to access the screw. Once the handle is loosened, look for a small access panel or a stamped area on the valve body behind the handle. In many Moen designs, you can find the identifier stamped on the side of the cartridge or the stem. Using a bright light and a mirror can help you read these tiny imprints without disassembling the entire fixture.

Handle Base Under the decorative cap, stamped on the valve body.
Spout Base Where the spout meets the deck or sink surface.
Cartridge Removed during repair; often has the model printed on it.

Utilizing Digital Resources

When the physical stamping is difficult to read, turning to the internet is the next best option. Moen’s official website features a robust "Find Your Product" tool that allows you to identify fixtures by visual selection. Furthermore, taking a clear photograph of the fixture and using a reverse image search can lead you directly to the product page, where the model number is displayed in the item details.

Decoding the Number

Once you locate the identifier, you might notice a specific structure to the code. While the format can vary, it usually consists of a combination of letters and numbers (e.g., "76240" or "M-7725"). The first few digits often indicate the style or finish, while the later numbers specify the handle configuration or flow rate. Understanding this breakdown helps when searching for compatible accessories or verifying the authenticity of replacement parts.

With these strategies, you can confidently track down the identifier for any Moen bathroom fixture. This knowledge empowers you to move forward with any maintenance task, ensuring a perfect match every time.
