How to find 'secret' shows on Netflix

This guide to secret codes will allow you to quickly narrow down your Netflix search whether you want to watch a drama (5763) or a silent movie (53310).

All you have to do is work out what genre of show you'd like to watch.

When entering the Netflix URL into the web browser, select the code from the list below and add it to the URL, for example, www.netflix.com/browse/genre/xxx which will lead you to a host of movies or TV shows only in that certain genre.

The codes can lead to some very specific areas, for example, instead of browsing Action films, you can narrow it down to just comic books and superhero films (10118) or just martial arts films (8985).

Or if you're only interested in watching a miniseries you can type in 4814 and for classic TV shows, you can type in 46553 to get a range to choose from.

On top of that, you can even search by time duration for example, 30-minute laughs can be found under 81602050 or 90-minute family movies under 81466229.

You can find the full list on Reddit which has been upvoted more than 140 times and has over 1.3k comments.
