There are two ways to access the secret collections. You can do it from any desktop by typing 'netflix.com/browse/genre/' into the URL and adding a unique ID code. Alternatively, if you use Netflix on a TV, you can simply type in the code to the 'search' bar. It does not work on mobile or tablets.

9875 is the Netflix secret code for true crime documentaries. You can put this number after the URL in your browser's address bar. Secret codes are Netflix's gateway to titles tied to a specific genre. This lets you bypass your recommended feed, and access the entire Netflix catalog.

YouTuber SetupSpawn shared that very trick with his subscribers, showing how he could search for superhero and comic book flicks simply by using the code 10118. There are a host of other codes that can find you just what you want on the site, including 869 for dark comedies and 6384 for tearjerkers.
