Common questions about .us domains

How many .us domains are registered?

Our database currently indexes 923,130 .us domains, comprising 895,182 root domains and 27,948 subdomains. This count reflects actively registered domains discovered during our daily crawling cycle.

How fresh is the domain data?

All domain lists are refreshed every 24 hours. New registrations, expirations, and DNS changes propagate within one day — significantly fresher than weekly or monthly alternatives.

Can I export or download the full .us list?

Yes. Subscribers can download the complete .us dataset as CSV with domain and TLD columns, plus access enriched DNS records, filters, and streaming exports with no row limits.

What is the difference between root domains and subdomains?

A root domain is a domain registered directly under .us (e.g. example.us). A subdomain is a child of a root domain (e.g. www.example.us or mail.example.us). Both are included in our .us domain list.
