CORE is a not-for-profit membership association of Internet domain name registrars and registries. Its purpose is to operate, on a cost-recovery basis, a shared registration system (SRS) for Internet domain names.

CORE was created in 1997 based on the Generic Top-Level Domains Memorandum of Understanding (MoU) in order to launch new names spaces. Since inception, CORE has been active in the development of protocols and methodologies to facilitate access to domain registrations, including a multi-protocol Shared Registration System (SRS) and registration gateway.

Who are CORE members?

CORE's members are registrars who register and maintain domains on behalf of their customers through CORE SRS and gateways. To register domains and to get value added services, please check the list of members offering registration services.
