Our mailing address is:
4327 Butler St
Pittsburgh PA 15201
We have mail cubbies in the front of the office with numbers and names. If you'd like a mailbox, put your name on it. If you'd like to get mail, add the number of the box to incoming mail, like this:
Some One
4327 Butler St
Suite 12
Pittsburgh PA 15201
The mail is community sorted. If you see mail in front of the mail cubbies, pick up the stack and put mail with Suite numbers in to cubbies with matching numbers. No one is currently responsible for sorting mail. Sometimes mail piles up unsorted. Be warned.
Since we have so many members, on most days we have a UPS employee come to the space. There is a place to leave your pre-packaged UPS deliveries to be picked up. Again, this is an ad-hock system.
The numbers are to make it easier to find the correct box. Previously, we just had user names, and matching a letter with a sea of un-sorted names was very difficult. Having number facilitates community sorting. The numbers also facilitate better google foo. If one exact address has too many business names attached to it, google penalized those companies as they seem less real. If you care about people finding you on the inter-webs, because use a number.
The mail is community sorted for the simple fact that it keeps costs down.
