iPhone delivery request

Hi, I just ordered a new iPhone and it's a present for my mom we are currently living in the same house so when the mailman comes and drops the package off at our house my mom will probably open it. It's already in the process of being put together and get ready to ship it will be here in two days, on the 7th. Is there a way I can contact someone to tell them to leave it in a special spot? I've seen the option before… I'm confused is this a possibility or not
