    About .ntt domain

    .ntt is a brand gTLD delegated through ICANN's 2012 New gTLD Program and operated exclusively by Nippon Telegraph and Telephone Corporation (NTT), Japan's largest telecommunications carrier. The TLD was delegated to the Root Zone on February 3, 2015, making it one of the brand extensions established during that first major expansion of the domain name system. As a dotBrand TLD, it exists solely to serve the NTT corporate identity and is not available for public registration. NTT applied under the initiative branded ".ntt INITIATIVES," with the stated goal of protecting and elevating the NTT brand in the global market.

    Who can register .ntt domain

    .ntt is not open to the public. Nippon Telegraph and Telephone Corporation is designated as the sole registrant, meaning no external individuals, businesses, or organizations can apply to register a .ntt domain through any commercial registrar. The TLD functions entirely as a controlled brand namespace for NTT and its group companies.

    How to register .ntt domain

    .ntt is a brand TLD reserved exclusively for use by Nippon Telegraph and Telephone Corporation and is not allocated through commercial registrars. ICANN delegated the TLD directly to NTT as the registry operator following a successful application in the 2012 New gTLD round. NTT noted in its application that registry operations would be outsourced to a designated third-party provider, but domain registrations remain entirely internal to the NTT Group. There is no public registration pathway, checkout process, or registrar channel through which an outside party could obtain a .ntt domain.

    Typical uses of .ntt domain

    .ntt domains are used exclusively by Nippon Telegraph and Telephone Corporation and its affiliated group companies to represent their brand across digital channels. Rather than competing with generic or country-code extensions, .ntt serves as a controlled namespace that signals official NTT Group ownership and authenticity. Typical applications include branded product pages, corporate service portals, and internal or consumer-facing digital properties where NTT wants to reinforce its identity and protect its brand from misuse in the global domain space.

    Tips for registering .ntt domain

    • Because .ntt is a brand TLD restricted to NTT's internal use, there are no public registration terms, renewal pricing structures, or WHOIS privacy considerations relevant to outside registrants.
    • No premium domain market exists for .ntt — the registry does not release names to third parties, so secondary-market acquisition is not a viable path.
    • Disputes over .ntt domains are governed by ICANN's standard dispute resolution frameworks, but given the exclusive-use nature of the TLD, third-party trademark claims against .ntt registrations are unlikely to arise in practice.
    • Organizations that believe their trademark rights are affected by a brand TLD delegation may engage ICANN's formal objection and post-delegation dispute processes rather than standard UDRP proceedings.

    Frequently asked questions about .ntt domain

    Who operates .ntt domain?The registry for .ntt domains is NIPPON TELEGRAPH AND TELEPHONE, administered by NIPPON TELEGRAPH AND TELEPHONE CORPORATION.
    Who can register a .ntt domain?

    .ntt is exclusively reserved for Nippon Telegraph and Telephone Corporation and is not available to any outside party. No eligibility pathway, verification process, or application channel exists for individuals or organizations outside the NTT Group. Unlike open or even restricted gTLDs, this TLD was designed from the outset as a single-registrant namespace.

    Can I transfer a .ntt domain between registrars?

    Because .ntt domains are not registered through commercial registrars and are held solely by NTT as the registry operator, standard inter-registrar transfer procedures do not apply. There is no EPP transfer process, transfer authorization code, or registrar-to-registrar movement available to the public. The concept of transferring a .ntt domain between registrants is outside the scope of how this TLD operates.

    Can I dispute a .ntt domain if it conflicts with my trademark?

    ICANN's Uniform Domain-Name Dispute-Resolution Policy (UDRP) technically applies to gTLDs, but because .ntt operates as a single-registrant brand TLD, all domains under it are controlled by NTT itself. If you believe the TLD's delegation or use infringes on your rights, ICANN provides a Post-Delegation Dispute Resolution Procedure (PDDRP) specifically designed for disputes involving registry operators rather than individual domain holders. This is a distinct process from the standard UDRP used for open TLDs.

    Was there a Sunrise or trademark claims period for .ntt?

    Sunrise and trademark claims periods are mechanisms designed to protect brand owners when a new TLD opens for public registration, giving trademark holders early access before general availability. Because .ntt was never opened for public registration — NTT being the sole registrant from the outset — no Sunrise period or trademark claims process was applicable or conducted for this extension.

    What was the purpose behind NTT applying for its own TLD?

    NTT's stated rationale, outlined in its ICANN application, was to acquire and protect its iconic brand identity in the global domain namespace under the initiative called ".ntt INITIATIVES." The TLD was intended to create a safer and more secure domain environment for NTT Group services, extend brand value across international markets, and generate synergy among NTT Group companies by providing a unified, authenticated digital presence distinct from generic or shared extensions.
