Challenge Checkers

Here, you can check whether you qualify for Challenge caches around the world.

All Challenge caches published after the 2016 moratorium are required to have a correct, working Project-GC Challenge checker linked from their listing. However, most checkers are written and maintained by community members rather than by the cache owners themselves — and checkers for Challenge caches from before the moratorium may be less reliable or "unofficial". Like anyone, the people behind them make mistakes, so please double-check a checker's result before you log a Challenge cache as found.
