COD MW4 Stranded Codes: Every Keypad Solution and Hidden Bunker Code

Why the COD MW4 Stranded Codes Matter

The Stranded level in Call of Duty: Modern Warfare 4 hides a set of optional keypad puzzles behind locked doors, and each one guards a Yellow Supply Cache or crate stuffed with useful gear. If you're hunting down all the COD MW4 Stranded codes, this guide gives you every solution in one place so you can stop doing mental math and get back to the fight.

These puzzles are entirely optional, but skipping them means leaving loot on the table. In a campaign level that rewards exploration, knowing the COD MW4 Stranded codes up front turns a scavenger hunt into a quick supply run. Below you'll find every keypad location, the clue pattern, and the exact four-digit answer, including the two Hidden Bunker codes that trip up most players.

All Stranded Keypad Codes at a Glance

Here's the full table of COD MW4 Stranded codes so you can screenshot it and go. Each entry lists the puzzle name, the clue numbers shown on the note, and the correct four-digit solution.

That's eight keypads in total. Six are standard pattern puzzles, and two are the Hidden Bunker codes that require you to add up outpost numbers scattered around the map. We'll break down the logic for each one so you understand why the answer works, not just what it is.

How the Stranded Keypad Puzzles Work

Almost every keypad in the Stranded level follows the same design: a note nearby shows three previously used codes, and you have to spot the pattern to find the fourth. The game is basically testing whether you can read a number sequence.

There are two main puzzle types you'll encounter:

• Arithmetic sequences — each number increases by a fixed amount (for example, adding 6 each time).
• Digit-shift sequences — each digit in the number climbs by one position (for example, 3456 becoming 4567).
• Sum-based clues — the Hidden Bunker puzzles ask you to add up specific outpost numbers you find on the map.

Understanding these three patterns is the key to solving any COD MW4 Stranded codes puzzle you come across, even if you forget the exact answers. Community reports confirm the puzzles are consistent across platforms, so the solutions hold whether you're on PS5, Xbox Series X|S, or the Nintendo Switch 2 version.

Spotting Arithmetic Patterns

The Base Camp and East Village puzzles are pure addition. At Base Camp, the note reads 0006, 0012, and 0018 — each step adds 6, so the next code is 0024. At East Village, the clues 0012, 0034, and 0056 climb by 22 each time, landing on 0078. Once you see the gap between numbers, the answer is simple.

Spotting Digit-Shift Patterns

The Small Island puzzle is the cleanest example. The clues 3456, 4567, and 5678 each shift every digit up by one. Following that rule, the next code is 6789. The Big Sign puzzle works similarly but with mixed steps: 1000 to 1200 adds 200, then 1200 to 1230 adds 30, and the final jump to 1234 finishes the sequence.

Step-by-Step: Solving Each Keypad

Below is a walkthrough for every location, ordered the way you'd likely hit them while exploring. Use the tables and bullets to move efficiently and grab each Yellow Supply Cache.

Base Camp (Near the Radio Tower)

Head to the radio tower and look for the note beside the keypad. The previously used codes are 0006, 0012, and 0018, increasing by 6 each time. Enter 0024 to open the door and collect the supplies inside.

Big Sign

The Big Sign keypad gives you 1000, 1200, and 1230. The sequence tightens as it goes, ending on 1234. This one rewards a Yellow Supply Cache, so it's worth grabbing early.

Cliff Near Basecamp

This puzzle is the trickiest of the standard set. The clues are 9300, 6400, and 3500 — each drops by 2900. That means the next value is 600, entered as 0600. Inside you'll find a Yellow Supply Crate.

East Village

A straightforward addition puzzle. The clues 0012, 0034, and 0056 step up by 22 each time, so the answer is 0078. Grab the Yellow Supply Crate and move on.

Small Island

The digit-shift puzzle. With clues 3456, 4567, and 5678, each digit climbs by one, giving you 6789. A Yellow Supply Cache waits behind the door.

South of Jamming Station

This one looks intimidating but follows a clean rule. The clues 5903, 6805, and 7707 each add 902. Add 902 to 7707 and you get 8609. That's your final standard keypad code.

The Two Hidden Bunker Codes Explained

The Hidden Bunker puzzles are where most players get stuck, because the clue isn't a number sequence at all — it's a map-reading task. You have to find outpost numbers around the Stranded map and add them together.

Farm Field Hidden Bunker (0330)

For this bunker, the note tells you to add together every Outpost number tied to the Logistics Stations. Scout the map, note each Logistics Station outpost number, and total them up. The sum comes to 0330. If you'd rather skip the legwork, just punch in 0330 and claim your reward.

Island Hidden Bunker (0008)

The Island bunker asks for the sum of all Infantry Checkpoint outpost numbers. Add them together and you land on 0008. It's a small number that looks wrong at first glance, but it's correct — don't second-guess it at the keypad.

These two are the only COD MW4 Stranded codes that require you to leave the immediate area and gather intel. If you're speedrunning the level, memorize 0330 and 0008 and you'll never need to do the math.

Tips for Clearing Stranded Faster

Knowing the codes is half the battle. Here's how to move through the level efficiently and make sure you don't miss a cache.

• Screenshot the master table. Keep the full list of COD MW4 Stranded codes on your phone or second screen so you're not scrolling mid-firefight.
• Clear enemies before puzzling. Keypads sit in open areas, and standing still to enter a code leaves you exposed. Thin out hostiles first.
• Grab caches in a loop. Plan a route that hits Base Camp, Big Sign, and the Cliff first, since they're clustered near the starting area.
• Check every note. Even if you know the answer, the note confirms which puzzle you're at — useful when two keypads look similar.
• Don't skip the Hidden Bunkers. The Farm Field and Island caches tend to hold the best loot, so the extra travel is worth it.

Player experience suggests the Yellow Supply Caches respawn loot differently each run, so there's real value in opening every one. For broader context on the mode and how these caches fit into progression, see the official Call of Duty site for the latest on Modern Warfare 4.

Common Mistakes to Avoid

A few errors trip up even experienced players:

• Entering 600 instead of 0600 at the Cliff keypad (the game needs all four digits).
• Misreading the South of Jamming Station pattern as a digit shift rather than a fixed addition.
• Forgetting that the Hidden Bunker answers come from map numbers, not the note itself.

Double-check your entry before walking away — a wrong code means starting the input over.

Rewards Behind Every Stranded Keypad

Every keypad you crack pays out. Here's a quick look at what each COD MW4 Stranded codes puzzle gives you.

The exact contents vary, but Yellow Supply Caches generally hold better gear than standard crates. If you're gearing up for the rest of the campaign or jumping into DMZ afterward, clearing all eight keypads is a smart use of ten minutes.
