You are likely here because a child you are responsible for has received a letter from Puzzle Post.

Puzzle Post is a puzzle-based adventure encased in a single envelope – send an anonymous card to your friends/family, and they will have to solve the puzzles inside to unlock a personalised message and reveal the secret identity of the sender.

We understand you may want to check the identity of the sender and review the secret message before allowing the child to do so. If so, please click the blue box below to reveal the correct passcode. You may then access the secret message via the form below.

Note: The passcode below is the same as the answer to the puzzle set. Please keep this hidden from the child.
