All safe codes in Blue Prince

Safes can be found around the estate in Blue Prince, either out in the open or hidden to the eye, but you’ll need a safe code to open each one.

Each safe code can be found by using information from its respective room and around the estate, but coming up with the safe code is a puzzle in itself. Additionally, without a few critical hints, these codes are impossible to figure out. Once you open a safe, though, you’ll find one of the red letters, which will add some important lore to the Blue Prince story.

In this Blue Prince guide, we’ve detailed where to find all of the safes we’ve found so far, along with their safe codes and the thought process behind them.

[Ed. note: This guide contains spoilers for Blue Prince. If you only want to see the code to a specific safe, use the table of contents below to navigate to it.]

All Safe Codes in Blue Prince

Prior to giving you the safe locations along with their codes, you should know that you’ll receive a hint for each safe’s solution after completing the puzzle found in the Study Room. If you’d like to attempt to solve each safe code, make sure to finish that puzzle first!

We’ve found seven safes, each one containing a red letter, so far and we’re missing just one, which Blue Prince players broadly assume is located in a hidden safe somewhere around the estate. As of this writing, to the best of our knowledge, no players have found that safe (if it even exists). Check back later!

The seven safes can be found in the Shelter, Boudoir, Study, Office, Drafting Studio, Drawing Room, and behind a Red Door.

How to open the Shelter Time-Lock Safe

The Shelter’s time-lock safe functions a little differently than the other safes in Blue Prince. To open this safe, you’ll need to know the time and date. The first day you arrived to the estate is November 7, so you can add your total number of days minus one to November 7 to get today’s date.

On a day you’ve drafted the Shelter as your Outer Room, input today’s date and a time that is at least one hour ahead. Once the clock hits your assigned time, you’ll have four hours to return and see what’s inside the safe.

Boudoir safe code

The Boudoir safe, found in the corner of the room, is out in the open and taunting you. However, with the knowledge that codes are related to dates, you can use the Christmas photo on the vanity to solve the code.

Interact with the safe and input 1-2-2-5 to open the safe.

Study safe code

The Study safe is also out in the open, just sitting and belittling you for not being able to find out its secret code. With the knowledge that the safe code is a date, but also that there are no dates of any kind inside the room, it’s a tough one. Instead, look at the chess board on the table to find a black King piece sitting on D8.

This can be interpreted phonetically as “date” — or December 8. Input 0-8-1-2 into the safe to open it and claim its rewards.

Office safe code

The Office safe will only reveal itself after you’ve turned the dial inside the desk drawer, which also includes a paper featuring book titles such as “Count on March.”

In this room, you can find numerous statues of people related to the estate, but one of the heads is more important than the others — Count Isaac Gates. If you’ve never been to the Foyer, you might’ve never known what Count Isaac Gates’ bust looked like, but you can find three small Gates around the room.

Adding the three small Gates with the book title “Count on March,” and you’ll get the safe code: 0-3-0-3.

Drafting Studio safe code

Inside the Drafting Studio, you’ll find a perfect but miniature replica of a safe on one of the dioramas on a desk. Interacting with the safe will tell you its a perfect replica, but if you interact with the safe while you have a magnifying glass, you’ll see that it can be opened.

Next, with your magnifying glass, interact with the November calendar on the wall to find eight small gates around the Apple Orchard. If you combine the eight gates with the month of November, you’ll get 1-1-0-8.

Drawing Room safe code

The Drawing Room safe is not visible until you take a closer look at the drawing in the center of the room. In this drawing, you’ll notice that one of the candleabra’s arms on the fireplace is misaligned. Interact with the candleabra to reveal the safe behind one of the drawings inside the room.

For this safe code, you’ll have to look at each drawing’s small gait, which is how a person moves. There are two drawings with small gaits — the woman in a dress and man with an umbrella. Around the room, you can find four drawings of the woman and 15 drawings of the man, so if you combine the two, you’ll get the safe code 0-4-1-5.

Behind the Red Door lock code

For those who’ve reached the Inner Sanctum, you might’ve noticed a locked red door on the way. Behind the red door, you’ll find a locked gate that has a letter lock, but also has an “8” on the last dial. Knowing that each lock’s code is a date, the “8” is the day and the rest of the three dials need to make up the month.

The only month that fits in the first three dials, including each month’s abbreviation, is the month of May — making the lock code M-A-Y-8.
