Need some quick help - what is the second address line for when buying online?

[MeddyDuo]

I just got an apartment, and I want to order something online and have it shipped to my apartment. Do I put my address and apartment number on the same line, or is the second address line for my apartment number?

Whatever you'd like. Either
123 EDF Lane #12
or
123 EDF Lane
Apt #12

There should be an apt. no. box or something like that.
