The eight Stranded codes are 0024, 0008, 0078, 8609, 0600, 1234, 0330, and 6789. Use the location table below to choose the right one. The Island Hidden Bunker uses 0008; the Farm Field Hidden Bunker uses 0330. These are optional exploration locks in campaign Mission 10, rather than a requirement to open every container before continuing the story.
All eight Stranded keypad solutions
Keep the leading zeroes: a four-digit keypad still needs all four digits. The solutions are fixed across playthroughs, according to the All Things How campaign walkthrough and this eight-keypad gameplay guide.
| Keypad or container | Code | Landmark to identify the lock |
|---|---|---|
| Base Camp container | 0024 | Beside the blue radio tower, across the bridge from base camp |
| Island Hidden Bunker | 0008 | Island reached across the river in the southwest |
| South East Village container | 0078 | Container outside the southeast village |
| South of Jamming Station container | 8609 | Container south of the Jamming Station |
| Cliff near Base Camp container | 0600 | Container on the cliff near base camp |
| Big Sign container | 1234 | Beneath the large highway sign northeast of base camp |
| Farm Field Hidden Bunker | 0330 | Hidden bunker in the farm field |
| Small Island container | 6789 | Container on the river island in the northwest |

If you are matching a saved note to a lock, use the note's location name. Several containers look alike; the number by itself does not identify the correct container. You can enter the solution directly without reproducing the arithmetic first.
The two hidden bunker clues
The Island Hidden Bunker asks for the total of the infantry checkpoints along the river. The relevant numbers are 1, 2, and 5. Adding them gives eight, entered as 0008. Checkpoint 3 is not part of that river clue.
The Farm Field Hidden Bunker uses the logistics stations instead. Add 100 + 200 + 10 + 20 = 330, then enter 0330. The different kinds of outpost are the important distinction: adding infantry checkpoints for this bunker gives the wrong result.
A note at the SAM site also lists the farm, river-island, and west-island solutions. It is another way to obtain those answers during exploration, rather than an extra access requirement once you know the code.
The container patterns
For the Jamming Station container, the first digit increases, the second decreases, and the final pair advances by two, producing 8609. The cliff container's changing first two digits produce 0600. At the Big Sign, the sequence builds from 1 to 12 to 123, so its next entry is 1234. The southeast village sequence advances by 22 to 0078; the small-island sequence ends at 6789.
Use the Base Camp answer 0024 directly if you just want the supplies. The keypad solutions are the useful constant here; the nearby clipboard is there to let you work the answer out yourself.
Collecting supplies without losing the route
Opening these locks is useful for the notes and supplies inside, but solving all eight does not complete every Stranded collectible. The mission also has caches away from locked containers, including moving vehicles. If your aim is simply to advance the campaign, return to the marked objectives after taking the gear you need.
If you are collecting, check the note count in the backpack and keep track of the locations you have opened. You can fast travel to base camp and cleared outposts, which makes revisiting an overlooked container easier. A missing cache should be checked against its own location rather than treated as evidence that one of these fixed codes has changed.
