Supply lines can be created between settlements to share resources and inventory among them, by assigning settlers as provisioners in Fallout 4.


The requirements for creating supply lines are:

  • At least two owned settlements.
  • At least one free settler.
  • The first rank of the Local Leader perk.
  • The two settlements must not already be (directly) connected with a supply line.


Linking the settlements with supply lines provides the following benefits:

  • When building at a workshop or using a crafting station inside a linked settlement, one can craft using the Junk, Aid and Misc (Miscellaneous) items in the inventories of all linked workshops from all linked settlements (junk is automatically scrapped and does not have to be scrapped first).
  • Excess food and drink (either produced or in inventory) will be used to supply all the settlements in the supply network. This can allow certain settlements to specialize in food or water production to make up for others that may be less viable.
  • In the Pip-Boy "Workshop" menu, the game will show actual shortages for individual settlements with warning triangles, which causes unhappiness, but if the category is green, then the network is supplying the shortage.
  • Provisioners can double as friendly patrols and will engage enemies that obstruct their paths (if the player is in the vicinity). An abundance of supply lines intersecting the various settlements can make traveling across the Commonwealth much safer, particularly if the provisioner is equipped with adequate weapons and armor to deal with the kinds of enemies that they might encounter on their route.
  • It is possible to establish supply routes between the Commonwealth, the Island, and Nuka-World, giving one access to stored resources in all places.
  • If a provisioner is encountered in the wasteland, they can be given items that they will carry to the settlement they are assigned to. Thus, provisioners can be used as "personal movers" to clear up inventory space.


To create a supply line, use the workshop in one of the settlements, highlight a settler and press [Q] (or RB/R1 on XBOX/PS4) to display a list of owned settlements. Select the settlement to which the player character wants to link the current settlement.

To review existing supply lines, open the world map and press [C] (or L1/LB on PlayStation 4/Xbox one) to view all the settlements connected to the supply line network.

Settlers assigned to supply lines will become provisioners and will travel between settlements, at times leading a pack brahmin. To remove the supply line, simply reassign the provisioner to some other work object in their settlement.

  • The provisioner will actually travel between the two connected settlements, so it may be difficult to reassign the worker, since they may not be in their home settlement. It is also possible to reassign the provisioner using the Vault-Tec Population Management System that came with the add-on Vault-Tec Workshop.
  • Routes can be created without land access, so Spectacle Island can have a supply line formed with a settlement on the Commonwealth mainland.
  • Provisioners still count towards the population limit of their respective settlements, as well as food/water requirements, despite hardly ever being in the settlement.
  • Settlements share resources with all other settlements that are part of its supply line network. Two settlements do not have to be directly connected. In other words, if the Sole Survivor connects settlement A → B, B → C and C → D, then A, B, C and D will also share resources with each other despite not directly being connected since they are still part of the same network.
  • Provisioners will engage hostile creatures and enemies along their path, so it is advisable to equip them with appropriate weapons and armor so they can defend themselves.
  • Like companions, provisioners cannot die by enemy fire; with enough damage, provisioners will be briefly knocked down, but they will get back up after a while. They will, however, die from damage taken from the Sole Survivor's mines.
  • To change or update a provisioner's clothing or weapons, initiate dialogue and trade items with them.

Provisioners will attempt to follow roads if at all possible. This can be problematic as there are several locations that take the provisioner past or through static enemy locations such as the Scrap palace or through enemy spawning points such as the road directly east of the Starlight Drive In. A severe problem location is the road in front of the Medford Memorial Hospital, Malden Center, Slocum's Joe Corporate HQ and Med-Tek Research which has several static enemy locations as well as spawn points. This effectively cuts off the eastern settlements from the west.

However these hostile interactions will only occur when the provisioner and the potential enemies or hazards are in a currently loaded world cell. In practice this typically requires that the player character is in the same world cell as the provisioner or an adjacent cell.

A result of attacks against provisioners are unaccompanied pack brahmin wandering all over the map. The provisioner will recover from the attack and continue on its assigned route while the brahmin is left to its own devices. They may eventually result in the raining brahmin phenomenon where upon entering a cell the game doesn't have a location to assign the brahmin and simply places it at random on or above the terrain.


  • PCPC Creating a supply network with two overlapping circles (A → B → C → D → A and A → C) can make some of the settlements have their food/water set to 0. To fix this, one needs to remove one of the circles and then activate the workshop at the affected settlements to update their resources.[verified]
  • PCPC Playstation 4Playstation 4 When setting up a supply line, only settlements which are at least one settler under the population limit can be selected as a target. This may be a possible bug, since provisioners do not change the population of the targeted settlement.[verified]
  • Playstation 4Playstation 4 Provisioners that were moved to the destination of their supply lines may keep the title of provisioner and their backpack appearance. The provisioner can be assigned any regular settler task and the supply line indeed ceases to exist.[verified]
  • Playstation 4Playstation 4 Xbox OneXbox One Supply caravans and their respective provisioners can become stuck on their routes or just disappear despite the Pip-Boy still showing a supply line connected between two settlements. This can make it extremely difficult or impossible to make any changes to your supply lines after they have been established.[verified]
    • Possibly, the missing provisioner may be pinned down in combat. Arriving and 'rescuing' the provisioner will re-establish the supply line.
    • Go to a different settlement, relocate someone to the affected settlement. After confirming, immediately assign him/her as a provisioner to the other affected settlement. Make sure to do this as quickly as you can since there will be a delay before the system updates the list of destination settlements. Confirm assignment and allow the system to update, then immediately reassign the settler to another task like farming.
  • PCPC Playstation 4Playstation 4 When a provisioner is assigned a new supply route or another task or is moved to another settlement while they are visiting another settlement, the old supply route will remain active in the Pip-Boy supply lines map, and the resources from the previous route will still be available to the provisioner's original settlement.[verified]
  • PCPC If an automatron is created in settlement "A", moved to settlement "B" and immediately made a supply route from B to A (via "A" workshop mode) it can cause some bugs in settlement "A" like wrong numbers of settlement resources (food/water/people) or a permanent supply line. [verified]
    • A possible fix may be: fast travel to "B" settlement, find the bugged automatron and command it via workshop mode to do something else (like farming). While still in workshop mode, open the console, enter the command player.placeatme 20593 and close the console. Press Q on the newly spawned settler, assign it to the "A" settlement and set their home in the "B" settlement so to make them take the broken supply line route. Finally, assign the spawned settler to do something else to remove it from traveling. This should fix the broken supply line. The broken automatron can be reassigned to the same route.
  • PCPC It is possible to bypass the settler population limit in any settlement by intercepting provisioners as they arrive from other settlements and manually reassigning them to a local task.
