<p>because I filled in my address recently without adding the building name, instead I just had the street address of de neve and my room number... would that be a problem?</p>

<p>I have had packages arrive to me when I only put the address (no building name). I did not even put my room #!</p>

<p>That's fine. </p>

<p>I had something like: </p>

<p>351 Charles E. Young Drive West #A408
Los Angeles, CA 90024</p>

<p>they'll look up people's room numbers
but if you have a super common name like me, they might not find the right room
I just got someone else's letter o.0</p>
