That's why I wrote "name and phone number", not address. Probably should have written "name and phone number of a cell phone that you will have on the trip".
The reason for the odd colored zip ties or TSA locks with indicators is not to secure the bag (since baggage locks provide no real security), but to make the fact that it has been opened by someone else more obviously visible when you pick it up. That way, you can check to see if anything is missing or added before you leave the baggage claim area.
You and I both know the above but a "chacked in bag newbie" may not. My post was not a stab at you but just to add more detail to your very sound advice.
