Seven Knights Re:BIRTH Coupon Codes for September 2026

A public coupon is normally limited to one successful redemption per eligible account. If the same account already claimed it, another attempt can be rejected even while the coupon remains available to other players.

Yes, shared public coupons can normally be redeemed once by each eligible account during the campaign period. Region, account eligibility, or campaign-specific restrictions can still apply.

Open the account section inside Seven Knights Re:BIRTH and copy the Member code linked to the account that should receive the reward. Enter that identifier on the official coupon page before submitting the coupon.

The coupon may have expired, already been used by the account, or belong to a different service region or campaign. Check the current campaign conditions and make sure the Member code points to the correct account.

Successful redemptions are normally delivered through the in-game Mailbox. If the reward does not appear immediately, reopen the game or wait briefly before checking the Mailbox again.

Yes, but only when Netmarble enables the coupon again or fresh current evidence confirms that redemption has resumed. An old code should not be moved back to Active merely because a stale list still displays it.
