The cited community record has no confirmed active code. This does not mean the game can never add one; it means a usable code is not documented in the sources checked for this edition.
What counts as verified
A code needs a clear string, an in-game redemption entry point, and a dated successful check. A headline promising free rewards is not enough.
Where to check next
Review the official game page and the current in-game menus after updates. Do not enter unrelated Adopt Me codes or install a script to claim a reward.
When this page changes
A future update should list the exact code, reward, expiration if known, and the date it was tested.
As checked for this edition, no active code is confirmed.
