Crush Washer Part Number

I've been trying to verify the part number for a crush washer on the oil drain plug / bolt. On a mazda oem website, under 2026 it doesn't even list Mazda3 Hatchback among the models.

Part #9956-41-400 appears to be consistent among many Mazda models and years. There just doesn't appear to be an answer that assures me I'm looking at the right part number for my car

The vehicle is a 2026 Mazda 3 Hatchback Carbon Edition.

Anyone know of a suggested website to use or the actual part number?
