How to Check Domain, Trademark, and Social Handle Availability at Once

Checking a business name’s availability “everywhere” means querying four independent systems that don’t share data: the domain (via RDAP, the IETF’s structured replacement for WHOIS), the USPTO federal trademark register, your state’s Secretary of State entity registry, and common-law useacross Google plus handles on Instagram, TikTok, YouTube, and LinkedIn. There is no master “name availability checker” — running all four, for every candidate, is the work.

This is the same four-system problem covered in our guide to whether a business name is taken. This page is about the how— how to run all four checks efficiently, in the right order, and why “available everywhere I looked” still isn’t legal clearance.

Is there one tool that checks name availability everywhere?

No — because there is no single registry that holds every business name. The phrase “name availability checker” is a search habit, not a real product, because availability is split across four systems that were built by different bodies for different purposes and never wired together:

• Domain registries (ICANN-accredited) — who owns the web address.
• The USPTO — who holds federal brand rights.
• State Secretaries of State — who registered the legal entity name, state by state.
• The open web and social platforms — who is actually using the name in commerce (common-law rights).

A name can be free in three of these and taken in the fourth. Any honest “check everywhere” workflow has to hit all four separately.

What order should I check name availability in?

Run the fastest knockout first so you stop spending time on names that were never going to survive. The order that wastes the least effort:

1. USPTO federal trademark register first. A confusingly similar registered mark in your industry class can kill a name no matter how free everything else is — so disqualify on this before you fall in love with anything.
2. The .com domain (RDAP). Cheap, instant, and a registered .com on a live site is the strongest single signal a name is in active use.
3. Your state’s Secretary of State entity search. Confirms the legal entity name is open in your formation state.
4. Common-law use on Google and the social handles. The catch-all for active brands that never filed a trademark.

Trademark-first ordering matters most when you’re screening many candidates: it’s the check most likely to remove a name from the running, so running it first shrinks the work for every step after it.

How do I check the domain properly?

Check the domain through RDAP or a registrar you trust, and look at the .com first. RDAP returns the authoritative registration record, which is what you want — not a registrar search box that flashes “available!” while steering you toward premium upsells. What this check proves: whether a specific address is registered and buyable. What it does notprove: whether you’re legally allowed to call your business that name. A taken .com is a marketing and credibility cost, not automatically a legal one — you can build a brand on a different TLD.

How do I check the USPTO trademark register?

Search the USPTO federal trademark register and run a knockout search — the exact name plus close variants, scoped to your Nice classification, the international class your goods or services fall under. Trademarks are class-specific: “Delta” coexists as an airline and a faucet brand because they don’t compete. What this check proves: whether a registered or pending federal mark is on file that could conflict. What it does not prove: that no common-law mark exists — rights can arise from use alone, with nothing ever filed.

How do I check the state Secretary of State registry?

Run your state’s Secretary of Statebusiness-entity search in the state where you’ll form the company. What this check proves: whether the identical entity name is already registered in that one state. What it does not prove: anything nationwide. A state registration secures the entity namelocally; it doesn’t give you brand rights and won’t stop a company in another state from using the same name. That’s what trademark registration is for.

How do I check common-law use and social handles?

Search Google for the exact name plus your industry, and check the handles on Instagram, X, TikTok, YouTube, and LinkedIn. What this check proves: whether a brand is actively using the name in commerce, which can create common-law rightsin that business’s geography even with no trademark on file. What it does not prove: that the handles being free means the name is clear — a regional company with an old website and zero social presence can still hold rights. Available handles are a good sign, never proof.

If a name is available everywhere I looked, is it clear?

No. Passing all four checks proves no exact matchexists in those systems — it does not prove the name is clear. The legal test isn’t “is the string identical,” it’s likelihood of confusion, which sweeps in misspellings, plurals, and phonetic twins of existing marks in your class. A name that’s free as an exact match can still collide with a similar registered mark. This is where a trademark attorney earns the fee — a formal clearance opinion is a legal judgment, and everything above is research, not legal advice. We always recommend getting an attorney’s opinion before you commit a finalist to print.

The faster way to check everywhere at once

Doing all four checks by hand, for every candidate, is the slow part of naming — a shortlist of 30 names is 120 separate lookups before you read a single result. Brand Cleared runs them automatically: an RDAP domain sweep, a USPTO federal knockout, social-handle probing across seven platforms, and a common-law SERP sweep — across about 100 candidate namesin 10 to 15 minutes, then scores and ranks what survives. It’s a research tool that does the mechanical work so you and your attorney can focus on the finalist.
