Life Is Strange Nathan Phone Code and Puzzle Solution

Navigating the complex investigation board in Episode 4 of Life Is Strange requires players to piece together critical evidence to unlock Nathan Prescott's locked smartphone. Accessing this device reveals vital messages that push Max and Chloe closer to discovering the truth behind Kate Marsh's disappearance. Unlocking the device serves as one of the key gameplay hurdles during the investigative chapter.
Finding the PIN Code via Nathan's Records
Players attempting to unlock Nathan's phone can immediately enter his four-digit PIN if they pay close attention to his personal files. His PIN corresponds directly to his birthday, which can be found by inspecting his Blackwell student record. Entering his birth date grants immediate access to his text history without risking a complete lockout.
For players using American date formats, the month comes before the day when entering the four numbers. This detail often trips up international players who are used to standard numerical sequencing. Checking your journal photos can help confirm the exact numbers needed.
Using the PUK Code Backup Method
If you accidentally fail the PIN entry three times, the phone will trigger a security lock demanding an 8-digit PUK code. Fortunately, players do not need to restart or rewind the scene to overcome this obstacle. The required PUK sequence is listed directly on the plastic U.S.A. Mobile SIM card found among Nathan's evidence clues.
Entering the digits 87897808 bypasses the security screen and unlocks the device instantly. This secondary solution ensures that progress is never permanently blocked regardless of initial mistakes. It also rewards thorough investigation of all physical items retrieved from Nathan's room.
Connecting the Clues on the Evidence Board
Unlocking the mobile phone is only one piece of the broader investigation board puzzle in Chloe's bedroom. Players must cross-reference Nathan's text timestamps with Frank's drug logs and David's surveillance records. Matching these data points establishes the exact timeline and location associated with the night of the Vortex Club party.
Connecting the phone messages to the correct coordinates highlights the Prescott family's hidden barn on the map. Once all four clue sets are properly linked, Max and Chloe can finally set off to inspect the secret location. Completing this board sequence represents the narrative turning point of the fourth episode.
Tips for Smooth Puzzle Resolution
To avoid confusion, make sure to inspect every piece of evidence until Max provides a vocal confirmation. Taking screenshots of documents during exploration allows you to reference dates and codes without backing out of menus. Taking a structured approach simplifies the deduction process significantly.
