Netflix has made it no secret that it utilizes very specific algorithms to show users content suggests that they may like based on their viewing history. It certainly appears as if those algorithms work nicely as the number of viewing hours on the streaming platforms continues to hit new record, but what if you want to look deeper and browse for content, either because you are new to the video streaming giant or because you just want to see what else is available in the genres you like?

Secret Netflix Codes Make Browsing Easier

Apparently there are some secret codes that make it easier to browse the ever-growing catalogue of content.

Browsing subcategories on Netflix

When using your web browser to look through the many categories, you’ve probably noticed that clicking on a category adds the word “genre” and a numbered code to the back of the link. However, changing that code number can bring you to a subcategory within the genre you are browsing, reports Alexis C. Madrigal of The Atlantic, who was the first to discover the codes and sent a bot crawling through Netflix’s website for the purpose of collecting all the codes.

“What emerged from the work is this conclusion: Netflix has meticulously analyzed and tagged every movie and TV show imaginable,” he wrote. “They possess a stockpile of data about Hollywood entertainment that is absolutely unprecedented.”

Apparently there are nearly 77,000 different subcategories in Netflix’s massive catalogue!

For example, you can pull up a list of children’s movies based on books with the link netflix.com/browse/genre/10056 or a list of B-horror movies with the link netflix.com/browse/genre/8195.

Netflix codes revealed

Netflix engineers reportedly created these subcategory numbers so that they could easily find them, which makes sense. Could you imagine working at the video streaming giant and trying to search through the massive catalogue when working with the database? And that catalogue is growing swiftly as the company brought 130 more countries online recently and now covers most of the globe.

It seems some have been experimenting with these codes and have drawn up lists of the codes for avid users. They’ve even been kind enough to post them online for the rest of us. It should be noted, however, that not all of the codes will work. They may differ by country, and they might change due to the ever-evolving nature of the video streaming giant’s catalogue.

At any rate, you can find a couple of the lists here and here.

As of this writing, shares of Netflix are up 0.3% at $114.90 per share.
