3. Zone Details: .rio
.rio is a geographic top-level domain designated for Rio de Janeiro. It is commonly used by municipal services, local businesses, cultural institutions, hotels and restaurants, event organizers, and residents who want a clear city affiliation. Typical use cases include official city portals, tourism guides, event pages, hospitality listings and hyperlocal community initiatives.
As a branding tool, .rio conveys immediate geographic relevance and local authenticity, useful to Portuguese-speaking audiences as well as international visitors seeking Rio-specific information. Organizations choose it to emphasize city ties, support targeted marketing and create memorable, location-focused domain names that distinguish local offerings from national or global counterparts.
Registry policies govern eligibility and registration details, and many entities combine .rio with broader domains such as .com or .br for wider reach. Use .rio for landing pages, campaigns or services where geographic identity, localized content and clarity for residents or tourists are central to your online presence.

Coverage and methodology for .RIO 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.
Coverage depends on the zone and source availability. The dataset count does not guarantee every registered .RIO domain. Additions and removals describe observed changes between dataset observations; source changes and gaps can also affect counts. 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.
Use .RIO domain data in your workflow
Monitor brands and threats
Filter domain names for brand terms and investigate candidates with additional evidence.

.RIO domain list questions
How many .RIO domains are in the dataset?
The latest list contains 660 domain names, with a snapshot date of 13 Sep 2026. This is our dataset count, not a guarantee of the total number of registered domains.
How do I download the .RIO domain list?
Sign in with an account that has download access and use Download Full 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 .RIO 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.
