A .BIZ domain can support a company website, product landing page, ecommerce project, agency client site, SaaS service, or reseller portfolio. NiceNIC supports the full path after search: registration, renewal, transfer handling, DNS, bulk domain lists, reseller API use, and account support.
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 .BIZ 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.
IANA lists .BIZ as a restricted generic top-level domain sponsored by Registry Services, LLC. DomainTools' current TLD-count snapshot shows 1,252,442 .biz domains. This section explains .BIZ market scale, current legacy-gTLD positioning, selected public .BIZ sales examples, and practical use cases for buyers who want to register, transfer, or manage .BIZ domains.
DomainTools current TLD-count snapshot for .BIZ.
.BIZ share of 392.5M total domain registrations.
Total domain registrations across all TLDs in Q1 2026.
This chart compares major domain categories using Q1 2026 domain-name-base data and separately shows the current .BIZ count snapshot. .BIZ is part of the other established legacy gTLD category, so the standalone .BIZ row is displayed for visibility and is not added outside the total market.
The point for buyers is simple: .BIZ communicates business intent directly, gives teams another short legacy-gTLD option when the matching .COM is unavailable, and can work well for practical commercial projects.
.BIZ is widely understood as shorthand for business, making it a straightforward fit for commercial websites and service pages.
.BIZ has been delegated since 2001, so it belongs to the established gTLD generation rather than the newer extension wave.
For business terms, product names, and client projects, .BIZ can be a practical alternative when the matching .COM is already taken or priced too high.
Reliable public historical .BIZ growth snapshots are limited, so this module compares .BIZ with selected current legacy-gTLD count snapshots instead of inventing year-by-year growth.
Selected public .BIZ sales examples show that short names, one-character names, and clear business words have produced meaningful historical aftermarket sales. These examples are for market context only, not investment advice or a prediction of future resale value.
A small business, an ecommerce team, a digital agency, and a reseller platform do not manage domains the same way. Choose the option that matches your situation and prepare accurate registrant information before registration.
Use .BIZ when you want a direct business-focused domain for a company website, service page, or commercial project.
Use .BIZ for product pages, support portals, partner programs, launch campaigns, or practical business workflows.
Help clients check availability, register domains, manage nameservers, and keep renewals organized in one account.
Connect domain registration and management workflows through NiceNIC reseller tools when .BIZ is part of a wider TLD offering.
If you already own .BIZ 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 .BIZ 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 .BIZ. 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.

Yes. You can search one name on this page, or prepare multiple names through bulk domain search. For larger lists, prepare clear brand, project, or client notes so support can help you review names before purchase.
.BIZ can be useful when the matching .COM is unavailable, too expensive, or reserved for a different brand. It works best when the domain is connected to a real business, product, service, marketplace, or commercial workflow.
Eligible .BIZ transfers usually follow the standard gTLD transfer flow: unlock the domain, obtain the Auth Code / EPP code, confirm the domain is eligible for domain transfer, and make sure the registrant contact can receive transfer confirmation messages.
.BIZ has some public historical sales, especially one-character names and clear business words. However, buyers should not rely on assumed resale value. Use .BIZ when the name has a real business, brand, client, ecommerce, content, or project purpose.
