Unfortunately, you can't block spoofed, fake numbers.

Some call blockers allow you to block any type of number. For example my mother has a cordless phone that allows her to block calls from partial and calls from fake area codes.

Of course you can. You can also block the entire 206 area code if you choose. Which is what I do, along with the 202 area code. Indian & Pakistani frauds are particularly fond of using those area codes. They're not very bright.

I use an app called TrueCaller you can block anyone you don't want to receive calls from...

Called about 2 min ago from Seattle.  Didn't answer.  Blocked.
