What is a .io domain?
.io is the country-code top-level domain of the British Indian Ocean Territory. Internet Computer Bureau, part of Identity Digital, runs the registry. Anyone can register one, anywhere, and because developers read "io" as input/output it became the extension of tech products. Google treats .io as generic, not tied to a country.
- ccTLD, used as generic
- Open to anyone
- 1 to 10 years
- Free WHOIS privacy
- No local presence needed

FAQ
.io questions
What founders and developers ask before registering.
What does .io stand for?
Officially, the British Indian Ocean Territory: .io is its country code. Developers read it as input/output, which is why software companies adopted it.
Can anyone register a .io domain?
Yes. You don't need to live in or have a business in the territory. Register it like any other name, in your own or your company's details.
Is a .io domain good for SEO?
It doesn't hold you back. Google treats .io as a generic extension, like .com, so a .io site isn't tied to one country and can rank anywhere. What ranks is the content on the site.
Why does .io renew for more than the first year?
The first year is an offer (₹3,899); renewing costs ₹7,999 a year incl. 18% GST. The renewal price is shown before you pay, and the table above shows three years in full.
Is WHOIS privacy available on .io?
Yes, and it's free. It keeps the owner's name, address, email and phone out of public WHOIS lookups.
Can I move my .io to HostMentor?
Yes. Unlock it at your current registrar, get the transfer (auth) code and start the transfer from your dashboard. A transfer costs ₹7,499 incl. 18% GST.
