    About .aco domain

    .aco is a brand TLD, also known as a dot-brand, that was delegated as part of ICANN's New gTLD Program. It was delegated to the root zone on 27 August 2015. The registry is operated by ACO Severin Ahlmann GmbH & Co. KG, with technical backend services provided by Afilias. As a brand TLD, it was implemented as a closed registry, meaning it is not intended for general public registration.

    Who can register .aco domain

    Registration for .aco domains is strictly restricted. This TLD is a closed dot-brand, reserved exclusively for the use of the registry operator, ACO Severin Ahlmann GmbH & Co. KG, and its affiliated entities. It is not open for registration by the general public, companies outside the ACO group, or trademark holders. There is no public eligibility process or verification for external parties.

    How to register .aco domain

    The .aco TLD is not allocated through commercial registrars or a public registration process. As a closed brand TLD, domains are allocated internally by the registry operator, ACO Severin Ahlmann GmbH & Co. KG, for its own use. The company decides which domains to activate and how they will be used within its corporate network. The outcome is that only domains directly related to the ACO brand and its operations will exist under this extension.

    Typical uses of .aco domain

    The .aco extension is used exclusively by ACO Severin Ahlmann GmbH & Co. KG, a global leader in drainage technology. Domains under this TLD are typically employed for the company's internal digital infrastructure, brand-specific websites, and secure online services for its employees and partners. This allows ACO to create a cohesive, trusted, and controlled online namespace that directly aligns with its corporate identity, distinguishing its official channels from other entities on the open web.

    Frequently asked questions about .aco domain

    Who operates .aco domain?The registry for .aco domains is ACO Severin Ahlmann GmbH & Co. KG.
    Who can register a .aco domain?

    Registration is not possible for the public. The .aco namespace is a proprietary digital asset of ACO Severin Ahlmann GmbH & Co. KG. It is used solely for the company's internal purposes, and there is no application process or waiting list for external entities to obtain a .aco domain name.

    Can I transfer a .aco domain between registrars?

    Inter-registrar transfers do not apply to .aco domains, as they are not held through commercial registrars. All domains are managed directly by the registry operator. Since the namespace is closed, there is no mechanism for transferring a .aco domain to or from a third-party registrant or between different registrar accounts.

    Can I register a .aco domain if I have a trademark for "ACO"?

    No, trademark ownership does not grant registration rights for this TLD. As a closed brand TLD, the registry operator has exclusive rights to all second-level domains under .aco. Even with a valid trademark, you cannot register a domain through any registrar or sunrise process.

    What dispute policies apply to .aco domains?

    Standard public dispute policies like the Uniform Domain-Name Dispute-Resolution Policy (UDRP) are generally not applicable because the registry operator controls all registrations. Any potential disputes would be internal matters handled according to the company's own policies, not through ICANN-mandated procedures for open TLDs.

    Will .aco domains ever become available to the public?

    There is no indication from the registry or ICANN that the .aco TLD will transition to an open model. Brand TLDs are typically operated as closed registries indefinitely to serve the specific needs and security of the brand owner. Any such fundamental policy change would require a formal request to and approval by ICANN.
