3. Zone Details: .co

The .co domain began as Colombia's country-code top-level domain but is widely registered and promoted as a global namespace for companies and commercial projects. Registrations are available to anyone through many registrars, making .co a practical choice for startups, product launches, landing pages, and URL shorteners.

Its short, two-letter form conveys brevity and commercial intent, so brands choose .co when .com is unavailable or when they want a compact, modern identity. Because .co can be mistaken for .com, many businesses secure both extensions or configure redirects to avoid user confusion; registration and renewal prices are often higher than some generic TLDs.

For international use, .co is commonly positioned as a global option, but site relevance, localization, and technical setup matter more for discoverability than the extension itself. Organizations should review registrar policies, WHOIS and dispute resolution terms before registering premium names or building high-value portfolios.

Coverage and methodology for .CO data

The downloadable file contains domain names from available sources, one per line in gzip-compressed plain text. It is a domain list, not a raw DNS zone file containing resource records, a WHOIS export, or a verified list of active websites.

Partial domain coverage. This dataset contains .CO domain names collected from available sources. Coverage is partial: it does not include every registered .CO domain or verify whether a website is working.

The proportion of all registered .CO domains represented in this dataset is unknown. Changes in the count may reflect both changes in the namespace and changes in collection coverage.

Additions and removals describe observed changes between dataset observations, not confirmed registrations or expirations; source changes and gaps can also affect counts. The coverage label describes the current dataset and does not establish comparable coverage across historical snapshots. Verify registration status separately before outreach, security decisions, or domain purchases.

The daily update target is 9 AM UTC. Use each file's snapshot date when scheduling imports or comparing archives; delivery can be affected by source delays. Historical availability varies by zone and date.

For reproducible analysis, record the zone, snapshot date, downloaded filename, and filtering rules. Usage is subject to our dataset license; enterprise and redistribution licensing is available separately.

.CO domain list questions

How many .CO domains are in the dataset?

The latest list contains 3,345,538 domain names, with a snapshot date of 03 Oct 2026. This is our dataset count, not a guarantee of the total number of registered domains.

Is this a complete .CO domain list?

This dataset contains .CO domain names collected from available sources. Coverage is partial: it does not include every registered .CO domain or verify whether a website is working.

How do I download the .CO domain list?

Sign in with an account that has download access and use Download Domain List above, or automate the download with the API examples. Check plans and download limits before subscribing.

What format is the download?

A gzip-compressed plain-text file with one domain name per line. It contains domain names rather than DNS resource records, registration contact details, or website content.

Can I download historical .CO lists?

Available dates appear in the historical domain list table. Archive coverage varies, and downloads require historical access. See historical datasets for details.

Are removed domains expired or available to register?

Removal from an observed list does not establish expiration or availability. Check current registry or registrar information before attempting to register a name. The same limitation applies to expired / removed domain datasets.

When is the dataset updated?

All datasets have a daily update target of 9 AM UTC. Check the displayed snapshot date because source availability and delivery delays can affect individual files.
