It would be equally correct to write:
Town Hall, 128-142 High Road, Ilford, Outer Mongolia, IG1 1DD

No, because it makes no sense.

Neither of them are correct. Both of them would get delivered
correctly.

One has additions which are helpful (to the public if not the Post
Office's automatic sorting machine), the other is comedy.
