You can watch the British comedy‑crime series Code 404 mainly through Sky’s ecosystem in the UK, and it currently has very limited streaming availability in the US and some other regions.

Main streaming options

  • In the UK & Ireland, the show streams on NOW (formerly NOW TV) as part of the Entertainment Membership, and it is also available via Sky platforms (e.g., Sky Go / Sky TV on demand), since it originally aired on Sky.
  • In the US , the series has previously been available via Peacock , but current availability can be patchy and may disappear between licensing windows, so it may not always show as streamable right now.

Buy or rent options

  • In the UK , you can digitally buy episodes or seasons on services like Apple TV and Amazon Video , if you prefer to own them rather than stream via subscription.
  • In several regions, including parts of Europe and North America, physical DVD/Blu‑ray releases are available through retailers such as Amazon when streaming isn’t an option.

Regional availability notes

  • In some countries (for example, the Netherlands), Code 404 is currently not available on major streaming services and can only be obtained on DVD or Blu‑ray.
  • Because rights change over time, the safest quick check is to search the title on an aggregator like JustWatch for your specific country and then confirm on the listed service’s app before subscribing.

TL;DR: Try NOW or Sky if you’re in the UK; check Peacock or digital purchase (Apple TV / Amazon Video) in the US; and if you see no streaming options in your country, look for the DVD/Blu‑ray release.
