How to Check if a Business Name is Already Taken (Complete Guide)
Before committing to a business name, you need to verify it is not already taken. Here is a complete step-by-step guide covering domains, trademarks, company registers, and social media.
Why checking availability matters before you commit
Choosing a name that is already in use can lead to serious legal problems, significant brand confusion, and expensive rebranding costs. Many founders skip availability checks because they assume if a name is easy to find as a domain, it is safe to use. This assumption is wrong and can prove very costly. A name can be unavailable as a trademark even if the domain is available. A company can be registered in your state under your chosen name even if no website exists. A thorough availability check covers all of these scenarios before you invest in building your brand.
Step 1: Check domain availability immediately
The first and most practical check is whether the .com domain is available. Even if you plan to use a different extension, securing the .com protects your brand from competitor confusion. Use NameFinder to check .com, .io, and .ai availability for your business name instantly. If the .com is taken, you have three clean options: choose a different name, add a word to the name such as get or the at the start, or use a strong alternative extension like .io or .co.
Step 2: Search the business name register in your country
In most countries, business names are registered with a government authority. In the US, search the Secretary of State database for your specific state — each state maintains its own company register. In the UK, search Companies House which is free and instant. In Canada, use the NUANS database. In Australia, use ASIC. These searches are free and take under five minutes — there is no excuse for skipping them.
Step 3: Search the trademark database
A business can operate under a name without having a registered trademark, but a registered trademark gives the owner the legal right to stop others from using a similar name — even if you registered it after them. In the US, use the free USPTO TESS search. In the EU, use the EUIPO database. In the UK, use the IPO search. Search not just your exact name but also similar names and variations — trademark infringement does not require an identical name, just a confusingly similar one.
Step 4: Search Google thoroughly
A Google search for your exact business name in quotation marks reveals whether any established businesses are already using it online. Also search your name combined with your industry keyword. If multiple active businesses are using the name or something very close to it, reconsider even if no formal trademark exists — building brand recognition under a name that is already in use in your market is an uphill battle from day one.
Step 5: Check social media handles
Search Instagram, TikTok, X (formerly Twitter), Facebook, LinkedIn, and YouTube for your business name. Consistent handles across all major platforms are valuable for brand building and customer discoverability. If the main handles are taken, check if you can add a short suffix like hq or co without it looking awkward. If a handle is registered but the account is inactive and has no followers or posts, you can often report it to the platform for recovery.
Step 6: Check app stores if relevant
If you plan to build a mobile app, search the Apple App Store and Google Play Store for your business name. App store visibility matters for discoverability within those ecosystems, and a name collision in the app store can significantly harm your app marketing efforts.
What to do if your name is already taken
Do not give up on a name you love too quickly. Check whether the existing user is active — many domains and social handles are registered but never used. You can contact the owner and offer to buy the domain. Use NameFinder to generate alternative name variations automatically — often a small tweak like a compound word or different suffix makes the name available and even more distinctive than the original concept you started with.
