What's the difference between “Where do you live?” and “Where do you reside?
If we understand these two sentences “Where do you live?” and ‘Where do you reside? at the deeper level of the meanings, the speaker intends to convey to the listener, it is clear that the speaker wants to know the actual address of the listener.
Sometimes, the speaker may intend to know the permanent address of another person by asking ‘Where do you live?’
In the sentence ‘Where do you reside?’ it may be the speaker wants to know the temporary address of the person.
But grammatically, both sentences are correct.
