Quick answer
- No fixed public Hajin bunker codes exist yet. Every row below shows its region, exact location, confirmation status, source and last-checked date. DMZ rotations are marked as community reports, not facts.
- 13 campaign codes are confirmed across 4 verified groups; 1 DMZ code type is community-reported.
- 6 FOB stations gate the deepest rooms; upgrades are bought with DMZ Cash, not real money. Check what a craft costs in the 3D Printer calculator.
- 6 zones sit at High threat or above on the Hajin map; 28 official POIs are mapped with source and last-checked data.
DMZ / locks and codes
MW4 safe codes and keypad codes
Campaign keypads, Hajin bunker lock logic and the FOB upgrades that gate the deepest rooms. Fixed DMZ safe codes are not public yet, so every row states its status instead of guessing.
Looking for an early-access or redeem code? Those are account codes, not keypads. They open access, not doors, and they are covered on the MW4 redeem code page; this page is only about in-game safes, keypads and bunker locks.

Open all campaign codesHajin door logic
Hajin bunkers use multi-step door puzzles and intel notes rather than fixed public codes. The interactive map tracks which zones have the simplest approaches.
