    About .sina domain

    .sina is a brand gTLD (generic top-level domain) operated by Sina Corporation. It was delegated to the root zone in ICANN's New gTLD Program on 30 March 2016, with Afilias serving as the registry backend provider. The extension was created primarily as a defensive measure for international trademark protection within the domain name system. As a brand TLD, its purpose is to provide a secure, trusted namespace under the direct control of the brand owner.

    Who can register .sina domain

    .sina is a closed, single-registrant TLD. Initially and for at least the first three years from its launch, the only eligible registrant was Sina Corporation itself. The registry's policy outlined that eligible registrants could later potentially include subsidiaries, business units, official channels, services, products, campaigns, board members, staff, partners, and collaborators. Registration is not open to the general public and is strictly controlled by the registry operator.

    How to register .sina domain

    .sina is a brand TLD allocated through a non-commercial, internal process. The registry operator, Sina Corporation, is the sole entity that can initiate registrations. Domain names are allocated internally to authorized entities such as departments, products, or partners as defined by the company's policy. Requests are submitted and approved through Sina Corporation's internal governance procedures. The outcome is a second-level domain within the .sina namespace, registered directly with the operator's chosen backend registry services provider.

    Typical uses of .sina domain

    This TLD is used exclusively by Sina Corporation and its authorized affiliates to brand its online properties and services. It serves to consolidate the company's digital presence under a unified, trusted namespace, enhancing brand recognition and user experience. Typical uses include official channels, specific services, products, campaigns, and internal departments. The choice of .sina over a generic extension like .com signals official affiliation and provides a secure environment controlled directly by the brand.

    Tips for registering .sina domain

    • The TLD was launched with a single-registrant model, where only the brand owner could register names for an initial period.
    • Registration policies, including who is eligible to register, are defined and controlled entirely by Sina Corporation.
    • As a brand TLD, it operates under a closed registry model, meaning general availability to the public is not offered.

    Frequently asked questions about .sina domain

    Who operates .sina domain?The registry for .sina domains is Sina, administered by Sina Corporation.
    Who can register a .sina domain?

    Registration is restricted to entities authorized by Sina Corporation. This includes the company itself, its subsidiaries, business units, and officially recognized partners, staff, or collaborators. The registry operator maintains a closed model, evaluating and defining eligible registrants internally rather than offering open public registration.

    Can I transfer a .sina domain between registrars?

    Inter-registrar transfers are not applicable in the conventional sense for .sina domains, as the registry operates a single-registrant, closed model. Domain management and any internal reassignments are handled directly through Sina Corporation's internal processes and its relationship with the backend registry provider, not through commercial registrars.

    Can I register a .sina domain as a member of the public?

    No, .sina is not available for registration by the general public. It is a brand TLD created for the exclusive use of Sina Corporation and its authorized affiliates. The namespace is closed, and domains are allocated internally for official company use, channels, and services.

    What dispute policies apply to .sina domains?

    As a single-registrant, brand-protection TLD, standard dispute policies like UDRP are largely preempted by the registry's controlled environment. Any internal disputes would be governed by Sina Corporation's own policies and the contractual terms between the registry and its authorized registrants, rather than public ICANN consensus policies.

    Are there any plans to open .sina for public registration?

    The original application stated the single-registrant approach would be maintained for at least three years from launch and would be regularly evaluated. Any decision to open the TLD to a broader commercial marketplace would be made by Sina Corporation based on internal strategy, market demand, and user expectations after that initial period.
