WHOIS data is the official record of who owns a domain and how to reach them. Registries ask for it for every domain.
What it includes
It covers the owner's name, email, phone and address, plus the registration and expiry dates. It is the official reference used to prove ownership and settle disputes.
Why accuracy matters
- Wrong details can get the domain suspended.
- It is used to prove you own the domain when needed.
- Important renewal reminders reach you through it.
- Some extensions check it regularly.
