What to do with a phone left behind?

I feel like this is a stupid question, but I’m genuinely not sure what to do with a phone left behind by a student. <br><br>It’s a small flip phone. Obviously nobody will be claiming it anytime soon. No name, no lock code or anything, just a basic flip phone. <br><br>I have a box in my classroom to store phones and headphones that students forget, but this phone has been there forever. <br><br>I’m not sure what the school’s take on it is, but I have so many phones and electronics in the box that students forgot and never came back for. <br><br>What do I do?
