Agreed it's a pain to verify, I wrote the part number on the back of the wall plate after replacing mine last week. But if it's a faucet from a major brand, it might be on their website. It seems like each one only has a few different sizes. Answer from Firehed on reddit.com

r/askaplumber on Reddit: Moen Bathroom Faucet Identification Help
September 16, 2021 -

Hi, I have a Moen faucet in my bathroom. The handle is kind of worn down on the inside where it meets with the cartridge threshold, so much so that when the handle is fully toward the wall in the "off" position, the water begins to pour out of the spout again. I have temporarily resolved this situation by swapping the two handles, and using them in reverse (push toward wall to get water).

I am looking for a model number so I can hunt down a replacement handle. I have one discontinued candidate that is very close already, the CA84002: https://www.moen.com/products/Traditional/Traditional-Chrome-two-handle-low-arc-bathroom-faucet/CA84002.

However, mine is different from this model in that the handle moves independently of the "body" piece. See below. Can anyone help identify the type of faucet I have? Thanks.
