Search .CU availability with NiceNIC and build a Cuba-focused web presence with domain registration, transfer review, DNS tools, SSL, business email, bulk search, and reseller API support. .CU is useful for Cuban organizations, commercial projects, institutions, and eligible Cuba-related domain strategies.
Need more than one .CU name? Use bulk domain search or upgrade account level for reseller workflows.
.CU is the active country-code top-level domain for Cuba. CUBANIC supports second-level .CU registrations and third-level registrations under categories such as .COM.CU, .EDU.CU, .ORG.CU, .NET.CU, .GOB.CU, .INF.CU, and .NAT.CU, subject to the applicable eligibility rules.
Add funds and pay for domain services using supported crypto options such as USDT, BTC, ETH, and LTC. Automated crypto deposit recording helps account balances update quickly after successful confirmation, with no extra NiceNIC processing fee for automated deposits.
NiceNIC provides real human support, not only scripted replies. Our team can review your domain needs, explain practical options, and give account-level, transfer, bulk registration, and reseller suggestions to help your domain business grow.
NiceNIC does not take arbitrary action against domains. Abuse reports are reviewed based on available evidence, policies, and registry requirements, with domain owners guided to review, fix, or explain reported issues where appropriate.
Manage .CU together with 2,500+ domain extensions from one NiceNIC account, including country-code, generic, and new domain extensions. This helps businesses, investors, and resellers build global domain coverage more efficiently.
NiceNIC supports 47+ website languages, creating a multilingual registrar experience for international users and teams. This makes domain registration, renewal, transfer, account management, and support easier across different markets.
For hosting providers, agencies, platforms, and domain resellers, NiceNIC supports reseller API access for domain registration, renewal, transfer, DNS, account-level pricing, and custom nameserver services.
The .CU namespace is more policy-driven than open mass-market TLDs. Buyers should evaluate eligibility, naming rules, documentation, processing requirements, and whether the second-level .CU or a category such as .COM.CU is the right fit.
Official CUBANIC snapshot of domains under .CU and delegated .CU categories.
.CU namespace snapshot compared with 392.5M total domain registrations.
Total domain registrations across all TLDs in Q1 2026.
This chart compares the global domain market with .CU as a small country-code namespace. .CU is included as a separate reference point for scale, while the global category totals use Q1 2026 domain-name-base data.
A .CU domain is best considered when the project has a real Cuba-related purpose and can meet the applicable registry category and documentation requirements.
.CU gives websites a direct country-code signal for Cuba and may suit institutions, commercial entities, tourism, organizations, and local services.
CUBANIC supports second-level .CU and third-level categories such as .COM.CU, .ORG.CU, .NET.CU, .GOB.CU, and .NAT.CU for different registrant types.
.CU orders should be reviewed carefully because eligibility, documentation, naming restrictions, and approval steps can matter more than simple availability alone.
A reliable public .CU-only multi-year registration growth series was not found for this page build. Following the template rule, this module uses the current official CUBANIC namespace snapshot instead of inventing an annual growth curve.
Publicly reported premium .CU domain sales are limited, so this section does not display a fixed sales benchmark. For buyers considering a .CU domain, the main value usually comes from Cuba relevance, eligibility fit, naming clarity, and long-term use rather than published resale history.
A commercial project, public institution, tourism organization, resident applicant, and domain reseller may all need different .CU handling. NiceNIC helps you search availability, compare categories, and manage the domains that fit your project or customer strategy.
Use .CU when the project needs a Cuban country-code signal and can meet the relevant CUBANIC category requirements.
Consider .CU or .COM.CU when the name is connected with commercial goods, services, or Cuba-related business activity.
CUBANIC categories such as .EDU.CU, .GOB.CU, .ORG.CU, .NET.CU, and .NAT.CU serve different registrant types and policy purposes.
Use reseller workflows when you need to compare .CU with other Latin America, Caribbean, or country-code domains for multiple customers.
If you already own .CU domains elsewhere, transfer decisions should not be based only on one renewal invoice. Check transfer eligibility, ownership access, billing reliability, support response time, API needs, and long-term domain management.
Paste multiple .CU names, remove duplicates, review the count, and continue to bulk registration. This is useful for domain investors, brand teams, agencies, hosting providers, and resellers.
Enter one name per line, with or without .CU. The tool removes duplicates and prepares a clean list for bulk registration.
If your business sells hosting, websites, SaaS, agency services, or brand protection packages, NiceNIC reseller APIs can support domain registration, renewal, transfer, DNS, and account management.
