Wow, thanks for all the replies, everyone! I didn’t expect so many good suggestions. I think I’ll try sending a card to my friend since we’re close, and I’ll check out some of the apps you mentioned for safety stuff.
I’m still a bit unsure about what can you do if you have someone's address if it’s someone you don’t know well, but I guess it’s better to just not do anything in that case. Thanks again for the advice!
