What is the difference between Redemption Grace Period and Extended Redemption Grace Period?
There are two different forms of Redemption. After a domain expires and passes through any applicable renewal grace period, the domain may have a status of Redemption Grace Period (RGP) or Extended Redemption Grace Period (ERGP). The Redemption Periods are managed by the registry of the TLD. There is a fee to restore your domain from either Redemption status and it is not discountable. This fee is in addition to the domain renewal fee. To process a Redemption order, please follow the instructions in the article, "How to Recover Domains in Redemption Status".
Redemption Grace Period (RGP) domains may stay in your account for 30 - 60 days after any applicable expiration grace period has lapsed (the Redemption period is not the same every time, but usually it is about 45 days). After the RGP period has lapsed, they are deleted from our system and go into a 5-day Pending Delete status at the registry. Domains in Pending Delete status cannot be recovered. At the end of the Pending Delete status, the domain is deleted by the registry and is available for anyone to register as a brand new name. In order to greatly increase your chances of being the first to re-register the name, we recommend that you create an account with our aftermarket partner, NameJet.
Extended Redemption Grace Period (ERGP) domains may stay in your account for up to 90 days after any applicable expiration grace period has lapsed. After the end of the ERGP period, if you do not exercise your rights to recover the domain, you agree that you have abandoned the domain name services, and relinquish all rights and use of the domain name services per the registration agreement. There are typically no plans to drop or auction the domain at that time. The name will be deleted from your account, and the previous registrant data will be removed from the WHOIS. We may auction, sell, delete or dispose of the name at any time. You will not have an opportunity to recover the domain once the 90-day ERGP timeframe has lapsed. If you are interested in a domain you previously owned, we suggest you visit the domain to see if it may be listed as for sale by the owner. If not, you can do a whois lookup on the domain at http://whois.enom.com, and email the current administrative contact. If they utilize the ID Protect service, your email will be forwarded to the underlying email address. Keep in mind, if they are not interested in selling, you may not receive a reply.
