Code 404 has just burst back onto our screens with its brand-new third season, and with all episodes available now, we're sure fans will be binging their way through the boxset at speed.


Therefore, thoughts now to turn to whether the futuristic police comedy drama, which revolves around a cop revived using artificial intelligence who doesn't quite match up to his living predecessor, will be back for a fourth outing.

With a cast including Daniel Mays (Inside No 9), Stephen Graham (Peaky Blinders) and Anna Maxwell Martin (Line of Duty), the series has won itself a passionate fanbase over the years, but will they get to see more from the central crime fighting duo?

Read on for everything you need to know about Code 404 season 4.

Code 404 hasn't officially been renewed for a fourth season yet, but as the third has only just been released there shouldn't be any reason for alarm just yet.

News of a season 4 renewal may be just around the corner, so we'll make sure to keep this page updated with any new information as we get it.

As the series has yet be officially renewed for season 4, at this point it's difficult to say exactly when it would air on Sky and NOW.

Previous seasons have all aired around a year apart, on a fairly regular schedule. Therefore, if the series does return, we'd expect to see new episodes around this time next year, in Summer 2023.
