I see no justifiable reason to re-assign land line numbers without giving the people assigned to that number adequate time to get themselves properly situated. There should be a widely understood time limit from the time of loss that a number will automatically be held unless officially released by the user. And there should be reasonable accommodations for people to apply to extend the time that transfer is permitted in something like 3 month increments. It costs so little and helps people keep part of their identity during trying trying times.
