But... what does your comment have to do with burner phones?

A burner phone is a phone number whose owner is not officially registered somewhere as the owner.

A spoofed phone number is a false declaration that you're calling from number XXXXXXXXXX when in fact you're calling from YYYYYYYYYY.

You might notice that there is absolutely no relationship between these two ideas. You can be registered and lie about your phone number. You can be unregistered and not lie about your phone number.
