Why is My Code Not Working?
If a Chaos Zero Nightmare code cannot be redeemed, check the following common causes:
- The code has expired. Every coupon has a limited registration period. The previously available half-anniversary codes expired on June 30, 2026.
- The code was entered incorrectly. Coupon codes may be case-sensitive. Check for spelling mistakes, incorrect characters, or extra spaces before submitting.
- The code has already been redeemed. Each coupon can normally be registered only once per account.
- Your account has not progressed far enough. The in-game coupon registration option and mailbox become available after completing Chapter 1, Episode 4.
- The coupon is restricted by server or region. Some promotional coupons may only be available on selected servers or in certain regions.
- The reward mail has expired. Successfully registered coupon rewards remain in the mailbox for up to 30 days. Claim them before the mail expires.
