Quick answer: To check business name availability and register a domain, verify the name across four levels: domain registries (.com, .shop, .net), social media handles, state or local business registries (Secretary of State), and trademark databases (USPTO). Once confirmed available, immediately register the domain through a domain registrar like Namecheap to lock it in.
| Where to check | What it confirms | Action to take | Cost |
|---|---|---|---|
| Domain registries (.com, .io, .net) | The web address is free | Register the domain immediately | Free to search; ~$10/yr to buy |
| Social handles (Instagram, TikTok) | The username is free | Claim the handles immediately | Free |
| Secretary of State / business registry | No local company is legally registered | File LLC / business formation | Free to search; registry fees vary |
| USPTO trademark database | The name isn't legally protected | File trademark application | Free to search; filing fees apply |

How to Check Business Name Availability and Register Your Domain
[!TIP] Interactive Tool: Use our guided Check & Register Onboarding Wizard to step-by-step clear your business name across domain extensions, social media handles, Secretary of State corporate lookup databases, and USPTO trademarks.
You've found a business name you love. Before you design a logo or print a single card, you need to know one thing: can you actually own it?
To launch a business successfully in 2026, checking business name availability and registering your domain is the first and most critical milestone. A name is only usable if it is free where it counts—in domain registries, on social media, in legal registries, and in trademark databases.
Here is the part most guides skip: a name can be wide open as a .com and already gone on Instagram, or free on every platform but locked up by a registered trademark. To protect your brand, you need to verify all four layers and secure the domain name immediately. This guide walks you through the entire process step-by-step.
still available?
The four places you need to check
A name being "available" depends entirely on where you look. These four layers each tell you something different, and missing one is how founders end up rebranding six months in.
- Domains — your web address. Most people instinctively type
.com, so a taken .com sends customers to someone else. - Social handles — your name on Instagram, TikTok, X, and YouTube. Mismatched handles fragment your brand and hurt discoverability.
- Business registry — whether a company is already legally registered under the name in your region.
- Trademarks — whether the name is legally protected, which can override everything else.

Step 1: Check domain and social availability together
Start here, because it's the fastest and rules out most names in seconds. Instead of searching each registrar and platform one by one, run the name through a tool that checks them all at once.
Enter your name into Namecheckly's business name checker and you'll instantly see availability across .com, .io, .ai, .net and the major social platforms on one screen. If the .com is taken, check whether the site is active or just parked — a parked domain can sometimes be bought, while an active business is a reason to reconsider.
Prioritize the .com first. If it's gone, test variations like getyourbrand.com or yourbrandhq.com before dropping to an alternative extension.
Step 2: Search your business registry
A free domain doesn't mean the name is legally clear. Search your government business registry to see if a company already operates under the same — or a confusingly similar — name:
- United States: your state's Secretary of State business search
- United Kingdom: Companies House
- Australia: ASIC Connect and the ABN lookup
- Canada: the federal Corporations Canada database plus your provincial registry
If a registered business in your industry already uses the name, that's a strong signal to adjust before you go further.
US state registry shortcuts
Every state runs its own register on its own system, and finding the right search page is often the slowest part of the job. These pages link straight to the official search and explain what that state's register actually covers:
- California business name search
- Texas business name search
- Florida business name search
- Washington business name search
- New Jersey business name search
Remember that a clear state register only clears the name for filing in that one state — it grants no trademark rights and doesn't stop a business in another state from using the same name.
Step 3: Run a trademark search
This is the check with the most legal weight. A trademark owner can block you from using a confusingly similar name in their industry even when the domain and handles are free. Search the USPTO trademark database (free at uspto.gov) — or your country's trademark office — for your exact name and close-sounding variants within your field. If a clear match appears, treat the name as off-limits.
Step 4: Register what's available
Once the name clears all four checks, move quickly. Availability changes daily, and a name you haven't registered doesn't belong to you.
Register the domain right away through a transparent registrar like Namecheap — it offers fair renewal pricing and free WHOIS privacy for the first year — then claim your priority social handles even if you won't use them immediately. Locking everything in on the same day prevents a competitor or squatter from taking the pieces you skipped.
Check business name availability now
You don't have to run four tabs to get started. Enter your name in Namecheckly to check domains and social handles in one search, then use the registry and trademark steps above to confirm the legal layer. It's free, instant, and the surest way to commit to a name you can fully own.
