Buy an .io domain

If you’re looking to by an .io domain, it’s unlikely that it’s because you’re living in the British Indian Ocean Territory: .io is the country-code top level domain (TLD) for this archipelago in the Indian Ocean.

It’s far more likely that you’re in the technology industries, or starting a tech project. The domain has become the extension for new crypto and software companies because of the acronym ‘io’ meaning ‘input/output’. Plus, compared to other TLDs, it’s short and to the point, making it more memorable and less likely to conflict with your brand name.

It was first introduced in 1997, but it’s only in the last 10 years that it’s really caught on. So there are lots of .io domains still available - but they’re going fast! Search for the perfect .io domain today.

.io domain FAQs

How do I transfer my .io domain to 20i?

​To transfer a .io domain to us, you’ll need to get the domain name authorisation code from your current provider.

Then, you need to search for it in our ‘Transfer a domain’ tool in our control panel, My20i. You can then start the transfer, which can take up to five days (usually less, and your website will remain online). Once transferred you’ll start saving on renewals. For further information about all domain transfers, please see How do I transfer my domain to you?

That is up to you, but to be safe and protect your brand, we’d recommend buying other versions of your company name with different popular top-level domains.

For example, if you had the yourcompany.io web address, a competitor or criminal could buy yourcompany.com. They could use it to compete, or even worse: fool your customers into being scammed.

You need to sign up here, buy a domain or transfer one to 20i, then activate your free hosting package in the My20i control panel. Further details: How do I set up free hosting?

​No: with 20i, what you pay in the first year is the same price as renewal. That way, you can make savings of up to 50% compared to other domain name registrars.
