Paul Erickson Apartment number?

[Lyric]

Hi!

How are we supposed to find Paul's apartment number? I read both messages in the mailbox and on the staff desk, but I cannot read the apartment number on the mailbox. I only get the mailbox message content and the "mailbox are all locked" message when I use the eye and hand. The number is also not given if I check Paul info on a terminal. All this is really strange.
Edit: I got the number looking at a walkthrough but it was not clearly explained how it was supposed to be found.

I went to every door until I got the right one.

I am not sure if this should be solved by trials and errors. Strange...

if i remember right the mail was in one of the 2nd floor mailboxes row...all you had to check now was the 2nd floor and not the whole building


if in doubt you can ask nearly every person you encounter about the names in your notes, some may have infos for you. dont forget to call your friend via phone, he maye also have new informations

I love hearing about people brute forcing solutions like this.
