How many parts does La Casa de Papel (Money Heist) have?

How to get close to this number

Season counts for a series that ran a few years cluster around four to six, and this one ran from 2017 to 2021. Divide the run by roughly a year per part and you get five, which is the answer. Years-divided-by-cadence works for television exactly as it does for film franchises.

The word "parts" rather than "seasons" is not a stylistic choice, and the explanation says why. The show started on a Spanish broadcast network and was then acquired and restructured by a streaming platform, which re-cut the original episodes and continued the story under a different release model. The numbering reflects two different production regimes stitched together.

That history is the genuinely interesting part. A series that had already finished on national television was bought, recut, released globally and then continued — becoming one of the platform's biggest non-English hits in the process. A question about how many parts exist is really a question about where one production ended and another began.
