How expired codes are moved
Codes move to this list when the official redemption endpoint stops accepting them. We do not delete old codes - keeping the historical record helps players identify which older video or social post they are looking at.
Why a code may stop working
Most Evomon codes have a fixed redemption window tied to a milestone event. Once the window closes, the same string will not redeem. We never repurpose old codes with new rewards - if the string still works, it stays in the Active list.
