About Namechk

Namechk is a free online tool that checks whether a username is available across social networks and online platforms and whether a matching domain name is available across popular domain extensions, all in one search. It also offers free name generators for usernames, businesses, brands, products, podcasts and domains, plus guides on domains, web hosting, website builders and starting a business. Namechk was first launched in 2009.

Namechk is a username and domain availability checker. Instead of visiting every social network and registrar one by one, you type a name into the search bar on the Namechk homepage and see where it is still free. It is designed for anyone who wants a consistent name online: creators, gamers, small businesses, startups and brands.

A consistent name makes you easier to find and harder to impersonate. If your handle is the same on Instagram, TikTok, YouTube and X, and it matches your website’s domain, people can recognize you everywhere.

  • Check username availability on dozens of social networks and online platforms at once.
  • Check domain name availability across popular extensions such as .com, .net and .org, plus many newer TLDs.
  • Generate name ideas with free tools, including the username generator, business name generator, domain name generator, and platform-specific generators for Instagram, TikTok, YouTube, Twitch, Reddit, Snapchat, Roblox, Minecraft and gamertags.
  • Learn the basics of domains, DNS, SSL and web hosting through plain-English guides.
  • Start a business with state-by-state guides to forming an LLC and running a business name search.
  • Compare providers through reviews and roundups of web hosts, domain registrars and website builders.

Using Namechk takes a few seconds:

  1. Type a username or name idea into the search bar.
  2. Namechk checks the name against each supported social platform and domain extension.
  3. Results show which platforms and domains appear to be available and which are already taken.
  4. Click through to a platform or registrar to claim the name you want.

Availability results are a guide, not a guarantee. Platforms have their own username rules, may reserve certain names and can change how they handle inactive accounts, so always confirm on the platform itself when you sign up.

Yes. Searching for usernames and domains and using the name generators on Namechk is free, and you do not need to create an account or enter a credit card.

Namechk is supported by advertising and affiliate partnerships. Some links to registrars, web hosts and website builders are affiliate links, which means Namechk may earn a commission if you buy through them, at no extra cost to you. This does not change the price you pay.

Namechk is used by people at every stage of building an online presence:

  • Founders and small businesses checking that a new company name is available as a domain and on social media before they commit.
  • Creators and streamers looking for a handle that is free on every platform they plan to use.
  • Marketers and agencies reserving brand handles for clients and campaigns.
  • Gamers searching for a unique gamertag.
  • Anyone protecting their privacy who wants to see where their old usernames still exist, as covered in our guide on how to disappear online.

What is Namechk?

Namechk is a free online tool that checks whether a username is available across social networks and online platforms, and whether a matching domain name is available across popular domain extensions, in a single search. It also offers free name generators for usernames, businesses, brands, products, podcasts and domains, and guides on domains, hosting and starting a business.

Is Namechk free?

Yes. Namechk is free to use. You can search usernames and domain names and use the name generators without creating an account or entering payment details. Namechk is supported by advertising and affiliate partnerships, so it may earn a commission when you buy from some linked registrars, web hosts or website builders, at no extra cost to you.

How does Namechk check usernames?

When you enter a name, Namechk checks it against each supported social network and online platform and shows whether the username appears to be available or already taken. It also checks whether the matching domain is registered in popular extensions. Results are a guide, so confirm availability on the platform itself, since sites have their own username rules and reserved names.

Does Namechk register usernames or domains for me?

No. Namechk shows you where a name is available, but it does not create social media accounts or register domains on your behalf. To claim a username, sign up on the platform directly. To register a domain, use a domain registrar or web host. Namechk links to platforms and registrars so you can claim names quickly.

Why is a username shown as taken when I can’t find the profile?

A username can be taken even if you cannot see a profile. The account may be private, suspended, deactivated or reserved by the platform, or the name may be blocked under the platform’s username rules. Some platforms also treat names as taken if they differ only in capitalization or punctuation. Try a variation or use the username generator for alternatives.
