Not usually. If they don't know you, and you never put an envelope in the collection plate, and you don't have a child in the parish school, they usually try to purge you from the parish registry after 3-4 years.
People typically don't bother to notify the parish office when they (physically) move away, anyway, and there's no central database of parish registrations, so they have to do something like that.
We purge constantly but once a year we go through the whole list. If we don’t know, we call.
