How the .co WHOIS lookup works

Live .co RDAP data from the authoritative registry.

1Step 1

Enter a .co domain name

Type the .co domain into the search box. .co is Colombia's ccTLD but is marketed globally as an alternative to .com for companies and startups.

2Step 2

FetchWhois queries the .co RDAP server

.CO Internet (operated by Neustar/TransUnion) manages the .co registry. We resolve the RDAP endpoint via IANA and query it live.

3Step 3

Read the .co registration record

Registrar, dates, status, nameservers and DNSSEC are returned in a clean layout alongside the raw RDAP JSON.

.co domains: Colombia's TLD, the world's startup alternative

.co is the ccTLD for Colombia, but it has been marketed globally since 2010 as a premium alternative to .com for companies, corporations and startups. The name's abbreviation of 'company' or 'commerce' made it immediately intuitive, and major brands like Twitter (t.co) and Overstock (o.co) adopted it early. .CO Internet (operated by Neustar, now part of TransUnion) launched the global marketing campaign and operates the registry with gTLD-style open registration, meaning no Colombian residency is required.

WHOIS records for .co domains follow standard RDAP structure with registrar, dates, status codes, nameservers and DNSSEC. Because .co is marketed globally and operates under gTLD-like policies, most registrars apply GDPR privacy redaction. The .co zone has full DNSSEC support. Premium .co names — especially single-word dictionary terms — command high market prices similar to .com and .io.
