Can I renew my domain name before the grace period?

Domain names that are in the 30-day Redemption Grace Period can be redeemed (or renewed) before the end of the Grace Period. If you tried to redeem (or renew) your domain name that is in Redemption Grace Period, but were unable to do so, the registrar may be in breach of the Expired Registration Recovery Policy.
