As you explore the game, you’ll find several rooms that contain safes, each one secured with its unique passcode. One of these rooms is called the Office Safe, and it holds a locked safe waiting to be opened. In this article, we’ll guide you step-by-step on how to unlock the Office Safe in the game Blue Prince, which was released on April 10th, 2025.
Office Safe Code
Head to the office inside the mansion and open the drawer. Inside the drawer, turn the dial to reveal a hidden safe on the wall. Now, to unlock the safe, read the note to reveal the list of book titles. Most of these book titles are marked red, except for one: March of the Counts.

The clue for the code is March and Count. “March” refers to the third month, which gives you the number 03.

Then, if you look around the room, you’ll notice there are three busts of Counts. Putting those two clues together—03 for March and 03 for the three Counts—you get the safe code: 0303.
