How do I check if a company name is available?

Check five layers in order: entity registration in your jurisdiction, trademark registers for your goods and services, domain availability, social handles, and cultural or linguistic meaning in your target markets. A name is only available when all five clear.

Does an available domain mean the business name is free to use?

No. Domain registration is first-come, first-served and carries no legal weight. A trademark owner can force you to hand over a domain that infringes their mark, even if you registered it first.

Is registering a company the same as owning the name?

No. Entity registration only stops another company registering an identical entity name in the same registry. Brand rights come from trademark registration and, in some countries, from actual use in commerce.

Validation

Company Name Checker: What to Verify Before You Commit

"Is this company name available?" is really five questions wearing a trench coat. Most founders answer one of them — the easiest one — and find out about the other four much later.

The five layers of availability

Availability is not binary. A name can be free at the registrar, blocked at the trademark office, fine in English, and unusable in Spanish — all at once. Check the layers in this order, because the expensive ones come first.

Entity registration

Can you legally register the company under this name?

Where to check: Companies House (UK), state Secretary of State (US), ASIC (AU), Corporations Canada

The gotcha: Registering an entity name gives you no trademark rights. Two companies can share a name in different states and neither owns the brand.

Trademark

Has someone already claimed this mark for similar goods or services?

Where to check: USPTO, EUIPO, IP Australia, CIPO, WIPO

The gotcha: This is the only layer that can force you to rebrand after launch. Check it before the domain, not after.

Domain

Can you get a domain you would actually put on a business card?

Where to check: Any registrar; check exact-match .com plus your realistic alternates

The gotcha: A free domain proves nothing about legal availability. It is the weakest signal of the five, and the one founders over-weight most.

Social handles

Are consistent handles available on the platforms you will use?

Where to check: The two or three platforms your buyers actually use — not all of them

The gotcha: Taken-but-dormant handles are common. Platform reclaim processes are slow and rarely succeed.

Cultural and linguistic

Does the name mean something unfortunate in your target markets?

Where to check: Native-speaker review across your launch languages

The gotcha: The failure mode is not embarrassment — it is a market you quietly cannot enter later.

Why "the domain is free" means almost nothing

Domains are sold first-come, first-served with no legal review. Trademarks are examined, published, and enforceable. If those two ever disagree, the trademark wins — a UDRP complaint can transfer your domain to a mark holder regardless of who registered it first.

So an available .com is a nice-to-have on top of a cleared mark, never a substitute for one. Read the full comparison in domain vs trademark.

What getting it wrong costs

Rebrand cost line

Typical range

Redoing identity and collateral

$5k–$50k

Legal fees and settlement

$10k–$100k+

Lost domain and SEO equity

6–18 months of rankings

Re-education of existing customers

Hard to price, easy to underestimate

Ranges are indicative and vary widely by company size and market. The point is the order of magnitude: screening costs hours, rebranding costs quarters.

Free checks vs paid screening

Free tools are fine for the first cut. They will tell you whether the exact string is registered and whether the .com is parked. What they will not do is compare phonetic variants, weigh Nice classes, read pending statuses, or check meaning across languages.

That gap is exactly where rebrands are born — the name looked clear because the search was shallow.
