Rust Apartment Complex: How to Receive Mail in Your Rented Room

The Apartment Complex is a safe zone monument in Rust built around rentable rooms, player-run shops, and a working postal system. Mail here is not junk that spawns in a barrel. It is a set of mailboxes wired to individual apartments, and each one belongs to whoever is currently renting that room.

Quick answer: Rent a room in the Apartment Complex and keep its scrap upkeep paid. Every rented apartment has its own mailbox, and other players can send messages to that specific apartment. Without an active rental, you have no mailbox and cannot receive mail.

How mail works in the Apartment Complex

Mailboxes are attached to rooms, not to players. When you rent an apartment, that room’s mailbox becomes yours for as long as the rental lasts. Anyone at the monument can then send a message addressed to your specific apartment, and it lands in that mailbox for you to read.

Because delivery is tied to the room, the address stays with the apartment. If you give up the room or get evicted, the mailbox goes with it. Receiving mail therefore always comes down to one thing first, which is holding a room.

Rent a room to get a mailbox

Travel to the Apartment Complex monument. It is a safe zone protected by turrets, so you can move around the lobby and courtyard without being shot.

Speak to the receptionist in the lobby to start a rental. You can also browse which rooms are free from the computer station in the basement before you commit.

Pick a room type and pay the upfront scrap cost. Every tier comes with the basics, including storage, a bed or bag, a phone, and a built-in Tier 1 workbench, along with the mailbox that lets you receive messages.

Insert scrap into the slot next to your door to cover upkeep. This is what keeps the room and its mailbox active in your name.

Room type	Upfront cost	Daily rent	Units available
Basement Room	100 scrap	25 scrap	16
Standard Apartment	200 scrap	50 scrap	40
Penthouse	400 scrap	100 scrap	6

Higher tiers give you more space, extra storage, and better amenities such as a furnace, but the mailbox function is the same across every room. Any active rental can receive mail.

Keep your rental active or lose the mailbox

Rent is paid in scrap over time. If the upkeep slot next to your door runs empty, you are evicted, and all of the possessions inside the room are seized. That eviction also ends your claim on the room’s mailbox.

Rooms are treated as combat zones rather than perfect safe-zone bubbles. A master key bought from an NPC in the basement can break into a rented apartment for about five minutes of access, so the room itself is not fully secure even while you keep paying. The mail system keeps working as long as the rental is yours, but do not treat the room as untouchable storage.

How to confirm you can receive mail

You know the system is set up correctly once you hold a rented room with a mailbox tied to it and its upkeep is paid. At that point, your apartment has an address that other players can send messages to.

The two common reasons mail will not reach you are simple. Either you have not rented a room, so there is no mailbox in your name, or your rent lapsed and you were evicted, which removes your claim on the room. Fix either one by taking an active rental and keeping scrap in the door slot.

Once you have a room and keep it funded, the Apartment Complex behaves like a real building. Your mailbox stays yours, messages arrive at your door, and the only thing standing between you and your mail is remembering to top up the rent.
