Search 900+ top-level domain suffixes worldwide in one place, including type, managing organization, and registration restrictions.
You want to register a .tech domain for a tech blog or a .shop domain for e-commerce—but which suffixes are legitimate? Which have registration restrictions? Our curated top-level domain suffix list lets you see at a glance the 'identity' and 'rules' of each suffix. Whether you're building a website, protecting your brand, or investing, this checklist helps you quickly find the right choice.
Personal Blog or Portfolio: You don't need a mainstream domain like .com. Registering a .me or .design reflects more personality. Search for these two suffixes in the list to see their type (both are generic top-level domains) and whether registration has restrictions (generally open globally).
Enterprise Brand Domain Protection: Your company plans to register your brand name as multiple suffixes to prevent hijacking. You can use the list to filter all "new generic top-level domains (new gTLD)" (such as .inc, .company, .group), then check whether these suffixes are open for registration.
Selecting Suffixes for Cross-Border E-commerce: Choose country code top-level domains (ccTLDs) based on your target market, such as .de (Germany), .fr (France), .jp (Japan). Each ccTLD in the list notes whether it requires local entities, helping you assess registration barriers in advance.
A top-level domain (TLD) is the rightmost part of a domain name, such as .com in google.com. IANA (Internet Assigned Numbers Authority) categorizes them into three main types:
Since 2012, ICANN has also opened thousands of new generic top-level domains (new gTLDs), such as .xyz, .loan, .cafe, which ordinary people can freely register.
tech, and the table instantly filters all entries containing "tech" (.tech is an exact match, and .technology will also appear).Suppose you want to register a domain for a technical team with candidate suffixes .io and .dev. Let's look up their information together.
Step 1: Enter io in the search box. The list immediately displays one record: .io, categorized as "country code top-level domain (ccTLD)", belonging to the British Indian Ocean Territory, managed by Internet Computer Bureau. Registration requirement: Anyone can register (many ccTLDs have opened globally).
Step 2: Continue entering dev in the search box. You get .dev, categorized as "new generic top-level domain (new gTLD)", managed by Google (Charleston Road Registry). Registration requirement: Globally open, but some second-level domains may be reserved (such as chrome.dev). Note that the .dev suffix was previously for internal use and is now fully open.
Comparison and interpretation: Since .io is a ccTLD, it may appear less "official" on formal business websites, but the tech community recognizes it well; .dev is operated by Google with good compatibility, but typically costs more than .io. Our list doesn't directly show prices, but you can check with registrars for specific suffix pricing.
Each field in the list has practical significance:
| Field | Meaning and Decision Guide |
|---|---|
| Type | gTLD (Generic) → Most reliable, no additional constraints; ccTLD → May have country restrictions or require local identity; sTLD → Must meet specific conditions to register. |
| Managing Organization | If it's a well-known company or organization (such as Google, Amazon, ICANN-designated body), the suffix is usually more stable. If it's a small country's government, pay attention to whether renewal policies are transparent. |
| Registration Requirements | "Everyone" means anyone can register freely; "Restricted" means you need to provide proof (such as business registration number, ID, trademark, etc.). |
| Registration Term | Most suffixes allow 1–10 years minimum to maximum. If a suffix only allows 1-year registrations, you can't lock in long-term costs at once. |
An important distinction: If a suffix's category is "ccTLD" but registration requirement says "Everyone", it means that although it's a country code, it has actually opened to the world (such as .cc, .tv, .me). These suffixes are often used as creative domains, but you need to be aware of how that country's political stability may affect domain policies.
| Suffix | Type | Recommended Use | Registration Requirement |
|---|---|---|---|
| .com | gTLD | Business websites, universal first choice | Everyone |
| .net | gTLD | Network services, technology-related | Everyone |
| .org | gTLD | Non-profit organizations, public benefit | Everyone |
| .cn | ccTLD | Mainland China websites | Requires domestic business license or ID |
| .io | ccTLD | Technology, startups | Everyone |
| .xyz | new gTLD | Generic, affordable, creative | Everyone |
| .shop | new gTLD | E-commerce | Everyone |
| .edu | sTLD | Educational institutions | Certified schools only |
Q: Is the list in our tool up to date? How often is it updated?
A: We update based on IANA's Root Zone Database and ICANN's published new gTLD list, typically synchronized monthly. However, some niche suffixes may be added in shorter timeframes; it's recommended to verify on IANA's official website before registering.
Q: Why don't I see Chinese suffixes like .公司 or .网络?
A: Chinese top-level domains (such as .公司, .网络) do exist and are classified as internationalized domain names (IDNs). Our main list currently only includes pure ASCII suffixes. If you need Chinese suffixes, you can query IANA for IDN ccTLDs or gTLDs.
Q: Some suffixes show "Everyone" but registrars say they need documentation?
A: Our "Registration Requirements" field reflects ICANN-level rules and doesn't include additional checks imposed by individual registrars. For example, .de allows registration by foreigners, but some registrars may require you to provide a German hosting address. We recommend consulting your specific registrar directly.
Q: Can I register a domain directly from your list?
A: No. We only provide lookup reference and don't directly offer registration services. The managing organization link next to each suffix takes you to the official wholesale registry; you still need to find an ICANN-accredited domain registrar (such as GoDaddy, Namecheap, etc.) to purchase.
Q: Any recommended first-choice suffixes for beginners?
A: If budget allows, .com is always the safest choice. If .com is already taken, consider .net, .org, or your country domain (such as .cn). Newer suffixes like .xyz and .online are affordable, but have lower visitor recognition.
Now you can search for your preferred suffix in the list above, see what type it is and what restrictions apply, and then place an order with a registrar.
