We still haven't seen the physical meaning of numerical identity. We can't define it for an entity in any meaningful way. The only way to find out what is the numerical identity of an entity is to ask 'What do we think was the numeric identity of the entity when we [arbitrarily] assigned it?'. So basically it's a case of 'I know it when I see it'.
