What information should be put on stickers that identify a kids' items?

I am talking about the ID labels for lunch boxes, back packs, binders, etc. I realize they are mostly to keep track of items whithin the classroom or if a kid leaves something some place around the school, but there is the possibility of leaving it somewhere more public.

Name only? Name & address? Name & phone? Name & school?

I am not very comfortable including her address or phone number. Even putting the name of the school kind of worries me but I admit I might be going overboard there.

I was thinking her name and her teacher’s name would be perfect, but I won’t know her teacher’s name for several more weeks and would really like to order the stickers now. It is a small school and I doubt anyone else will have the same name.

Yes, I know I am totally over-thinking this.
