Netflix viewers say life has changed for the better after typing in '9875'

The 9875 Netflix hack could completely change the way you use the streaming service. Check it out:

The trick, which was shared on TikTok, will stop you from eating into your viewing time by endlessly scrolling for your next watch - if you're into a particular type of show, that is.

Nowadays, it's almost un-cool if you aren't up to date with your serial killers.

From Jeffrey Dahmer to Ted Bundy - these shocking individuals have been the topic of conversation in the true crime community for years.

However, with the biopics becoming so popular on Netflix, the serial killer genre is seemingly reaching new levels of popularity.

Well, if you're indeed a true crime lover, you'll be delighted to know that there's a much easier way to find what you're looking for.

Type '9875' into the platform's search box and huge list of Netflix's crime documentaries and biopics suddenly appear.

It's as simple as that.

"It works. Best way to find True crime on Netflix," one viewer commented.

Another said: "I didn't think this would work this is really cool thank you."

The only slight issue with the secret feature is that some viewers were reporting rather inconsistent and pretty frightening results.

"Peppa Pig also came up," one user wrote, while someone else also added: "I did it and Shrek Forever After came up."

For the non-serial killer lovers out there, it turns out that there's loads of different codes that are linked to different genres.

So, don't worry, we've got you covered.
