One of the reason I got a pixel is that you can get OEM repair parts (including adhesive!) staright from ifixit, no IMEI needed (such technology is simply out of reach for the like of apple):

You can get all the genuine part even for pixel 3, which is 5 years old and no longer supported (newer pixel phone is supported for at least 5 years, older phone are not supported because qualcomm no longer supports the SOC IIRC). You can get third party part from ifixit even for original pixel, and that is pretty incredible.
Disclaimer: This obviously is NOT a endorsement of pixel's repairability. display and battery are very much glued on the phone and way harder to open compare to the like of fairphone. You should watch some repair videos first before deciding if you want to repair this thing by yourself. I am just glad parts are readily avaliable, gives individual and especially repair shops a easier time of repair.
