One Search, Full Picture
Enter a keyword and see its status across 1,210 extensions at once: .com, .net, .org, country codes like .io, .ai, .de, and hundreds of new gTLDs. No switching between registrars.
Secure Your Brand
See exactly where your keyword is already taken and where it's still open. Spot gaps in your TLD coverage before competitors or squatters fill them.
Act on What You Find
Available TLDs show registration pricing. Taken ones show if they're listed for sale. Every result leads to a next step, not a dead end.
What is TLD Availability Check
DomainKits TLD Availability Check takes a single keyword and checks its registration status across 1,210 top-level domain extensions, covering both gTLDs and ccTLDs. Built on the data pipelines of ABTdomain.com. Enter a keyword, a full domain name like google.io, or even a URL like www.amazon.com, and the tool extracts the keyword and scans every available extension.
Results show whether each TLD is available for registration (with pricing), already registered, or listed for sale. This is the only DomainKits search tool that covers both gTLDs and ccTLDs in a single query, making it the primary tool for brand protection and TLD discovery.
Why Some TLDs Cannot Be Registered
A TLD showing as unregistered does not guarantee it can be registered. Some registries restrict certain keywords due to brand protection policies, reserved name lists, or premium pricing tiers. The tool shows pricing where available to help identify these cases.
How to Use Key Filters for TLD Registration Check
Results are organized by gTLD and ccTLD sections. The following filters help you narrow your TLD registration check to the extensions that matter.
Type
Filter by TLD category: "Popular TLDs" for the most commonly used extensions (.com, .net, .org, .io, .ai, etc.), "ccTLDs" for country code extensions, or "Other gTLDs" for the full range of newer generic extensions.
Status
"For Sale" surfaces domains whose owners have listed them on marketplaces. "Registered" shows taken extensions. "Possibly Available" shows extensions where availability requires further verification with the registry.
TLD Availability Check vs Active Domain Search
TLD Availability Check and Active Domain Search approach domains from opposite directions. TLD Availability Check answers "where can I register this keyword?" Active Domain Search answers "what's already registered with this keyword?"

Frequently Asked Questions
What is the difference between TLD Availability Check and Bulk TLD Check?
TLD Availability Check takes one keyword and checks it across 1,210 extensions (vertical search). Bulk TLD Check takes many keywords and checks each one against selected TLDs (horizontal search). Use TLD Availability Check for brand protection or finding alternatives for one name. Use Bulk TLD Check for scanning a keyword list.
Why does a TLD show as registered but I cannot find the website?
A domain can be registered without having an active website. It may be held for brand protection, future development, or resale. Domains marked "For Sale" have been listed on marketplaces.
Can I check availability for a full domain name like google.io?
Yes. The tool automatically extracts the keyword from a full domain name. Entering google.io, www.google.com, or just google produces the same result: checking the keyword "google" across every TLD extension.
Why are some TLDs not available for registration even though they show as unregistered?
Some registries restrict certain keywords due to brand protection policies, reserved name lists, or premium pricing. A TLD showing as unregistered does not guarantee it can be registered at standard cost. The tool shows pricing where available to help identify premium or restricted names.
Where can I see TLD registration trends and market data?
Visit the TLD Trends Dashboard for active domain counts and new registration trends across 1,000+ extensions. For deeper analysis, ABTdomain.com provides comprehensive TLD reports with historical data.
Why does DomainKits show fewer TLDs than some other tools?
DomainKits focuses on TLDs that are practically registrable by most users. We cover all core gTLDs and the major country-code TLDs, but exclude obscure third-level ccTLDs (like .com.om or .co.ck) that most registrars do not support. The 1,210 extensions we track already account for the vast majority of global domain registrations, giving you a clear and actionable picture of how a keyword is positioned across the market without noise from inaccessible extensions.
What is the difference between a gTLD and a ccTLD?
A gTLD (generic top-level domain) is not tied to a specific country: .com, .net, .org, .app, .io are all gTLDs. A ccTLD (country-code top-level domain) is assigned to a specific country or territory: .uk, .de, .jp, .ai. Some ccTLDs like .io and .ai have become popular beyond their original geographic purpose. DomainKits checks both types in a single search.
