Research brief
The .icu facts that change the decision
This page separates registry policy, public market evidence and registrar pricing. A sample is labeled as a sample; a rule is labeled as a rule; and a checkout quote is never presented as a registry statistic.

How to find a strong available .icu
Treat availability as the start of the decision, not the finish. A usable name also needs to be easy to communicate, defensible and fairly priced.
- 01
Start with a name that earns .icu
Explain the intended meaning in the title and test it with healthcare and non-healthcare audiences separately.
- 02
Search the exact label first
Keep the search scoped to this extension, then compare the exact label with closely related endings before accepting a spelling compromise.
- 03
Check rights and pronunciation
An available result is not trademark clearance. Say the name aloud, check local implications and review the registrar’s final eligibility rules.
