The Prime Zone is the main zone or universe which Sonic Prime is from, and is home to the planet from which he hails. It is possible to reach alternate dimensions from the Prime Zone through various means, mainly those within the Multiverse and, on incredibly rare occassions, worlds from other multiverses entirely. The Prime Zone is just one of many incarnations of Sonic's World throughout the multiverse, but it and the Prime Zone are the core reality, of which all others are derivations of varying degree.

- Ian Flynn has stated that if the Prime Zone was to be destroyed, no new Zones could come into existence.
