.io registration
.io is the country-code extension for the British Indian Ocean Territory, but it is widely associated with “input/output” in computing. That makes it particularly relevant to software companies, developer tools, APIs, infrastructure services, technology products and online platforms seeking a concise, technical identity. Registration is open and follows a first-come, first-served allocation process. No special application procedure is required. A .io label must contain between 2 and 63 characters. Before ordering through host.yt, check that the name is available and enter the registrant details accurately. To transfer an existing .io domain to host.yt, remove the registrar lock or other transfer protection and request the authorization code from the current registrar. Transfers can take several days to complete. Once the transfer is finalized, one year is added to the domain’s existing expiry date. Changing the registered holder requires authentication by both parties. Validation emails are sent to the current holder and the proposed new holder, and each must complete the requested confirmation. The request is cancelled if the process is not completed within five days. A holder change does not alter the domain’s expiry date.

Frequently asked questions
What does the .io extension stand for?
io is the country-code top-level domain assigned to the British Indian Ocean Territory. In technology, “I/O” also means input/output, so the extension has become closely associated with software, infrastructure, developer tools, APIs and digital products.
Who can register a .io domain?
Registration is open without a special application procedure. Individuals, companies and organizations can request an available .io name through host.yt. Domains are allocated on a first-come, first-served basis, so an available name is not reserved until registration succeeds.
Are there restrictions or documents required to register .io?
No special supporting documents or separate registration procedure are required. The requested name must be available, and its label must contain between 2 and 63 characters. Registrant information should be complete and accurate when the order is submitted.
Is .io a good choice, and what projects suit it?
io is a practical choice for software products, developer platforms, APIs, infrastructure services, open-source projects and technology startups. Its computing association gives visitors a clear technical signal, while the short extension works well with concise product or brand names.
When does .io make more sense than .com?
io makes more sense when a project is explicitly technical and the input/output association strengthens its identity. .com has broader mainstream recognition and suits general commercial audiences better. Choose .io for a focused technology brand; choose .com when universal familiarity is the priority.
How quickly is .io registered, and how long does registration last?
A registration request can be processed after the name passes the availability check and the submitted details are accepted. Allocation is first come, first served. The applicable registration term and expiry date are shown with the order and should be monitored for timely renewal.
How do I transfer a .io domain to host.yt?
Disable the domain’s transfer lock or other transfer protection at the current registrar, then obtain its authorization code. Submit that code with the transfer request to host.yt. Completion can take several days, and one year is added to the existing expiry date afterward.
