MW4 Campaign Door Safe Codes

There is no single universal safe code for Call of Duty: Modern Warfare 4 (the 2019 reboot’s sequel) because the game’s campaign does not feature any door safes with fixed codes. However, the original Modern Warfare 4 (as part of the 2022 Modern Warfare II) does include a few safe combinations in specific missions, and this article explains exactly where they are and how to open them.

Background: Safes in Modern Warfare 4

Call of Duty: Modern Warfare 4 is a common name for the 2022 release Call of Duty: Modern Warfare II (the sequel to the 2019 reboot). In its campaign, safes appear only in a handful of missions, usually as optional loot containers. Unlike some other games, these safes do not have randomized codes – each one has a fixed combination that is either found on a note nearby or deduced from the environment. The codes are not shared across missions, so you must locate each one individually.

All Safe Codes in Modern Warfare II Campaign

There are three safes in the Modern Warfare II campaign that require a code. Each is tied to a specific mission and a specific location. Here is the complete list:

• Mission: “Wet Workâ€� – In the cargo ship’s lower deck, you’ll find a safe in a small office. The code is 3-7-4, found on a sticky note on the desk nearby.
• Mission: “Dark Waterâ€� – During the raid on the marine base, there is a safe in the command center. The code is 1-9-8-4, written on a whiteboard in the same room.
• Mission: “Prison Breakâ€� – In the prison’s armory, a safe holds extra ammunition. The code is 2-6-4-4, printed on a poster on the wall opposite the safe.

Note that these codes are for the standard campaign. If you are playing on a higher difficulty or in co-op, the codes remain the same.

How to Enter the Codes

When you approach a safe in Modern Warfare II, you will see a prompt to interact. Press and hold the interact button (default: F on PC, X on Xbox, Square on PlayStation) to open the keypad. Use the number keys or D-pad to input the correct sequence, then press the confirm button. If you enter a wrong code, the safe will not open, but you can retry as many times as you like – there is no penalty.

Common Problems and Misconceptions

A frequent issue is that players assume the codes are randomized or that they need to find a code for every safe they see. In reality, only three safes in the campaign require a code; the rest are either locked with a keycard or simply cannot be opened. Another misconception is that the codes from the original 2009 Modern Warfare 2 (like the famous “1-2-3-4� safe in the “Contingency� mission) carry over – they do not. Each game has its own unique codes.

If you are playing the 2023 Modern Warfare III, note that its campaign has different safes and codes, which are not covered here.

Why the Codes Are Not Universal

The developers intentionally design safes as environmental puzzles. The codes are placed near the safe as part of the level design, encouraging exploration. This is a departure from older Call of Duty titles where safes were rare or non-existent. In Modern Warfare II, the safes are optional, and opening them yields bonus items like weapon blueprints or armor plates, but they do not affect the main story.

Alternatives to Finding Codes

If you cannot find a safe’s code, you have a few options:

• Look for notes, whiteboards, or posters in the immediate area – the code is almost always within sight.
• Use a walkthrough video or guide that shows the exact location.
• Skip the safe entirely – they are optional and do not block progression.
