Type any Fortnite Support-A-Creator code to see whether it is active, which Epic account it belongs to and whether the creator is verified.
Support-A-Creator codes let Fortnite players credit a creator when they buy V-Bucks or real-money items. Entering a code at checkout sends a share of the purchase to that creator. This checker queries the official Fortnite API, so the result is always the live status of the code.
