Find available .co domain names for a company
.co is short and company-like, but it can be confused with .com when spoken or typed. Evaluate that leakage risk alongside availability, price, and brand fit.
Because .co lacks a public RDAP endpoint, NameFinder uses a conservative WHOIS fallback and reports ambiguous responses as unknown rather than available.
Real RDAP Verification
Every name is verified live against official WHOIS/RDAP registries across .com, .io, .ai, .dev, and .app — no stale, cached guesses.
Multi-Namespace Handles
Check matching social handle availability across GitHub, npm, YouTube, X, and Instagram in one pass alongside your domain search.
Honest Registrar Prices
Transparent wholesale prices directly from Porkbun, Namecheap, and Cloudflare — zero affiliate price markups or registration traps.
Frequently Asked Questions
Is .co a good alternative to .com?
It can be concise and credible, but some visitors may type .com automatically. Consider who owns the matching .com and whether confusion creates risk.
How does NameFinder check .co?
It uses the host WHOIS service and only marks a name available when a clear registry not-found marker appears. Ambiguous output remains unknown.
