How to Check If a Business Name Is Taken: A Four-Database Clearance Workflow

Finding no exact match in one search box does not prove that a business name is available. A name can pass a company-register search but conflict with a trade mark. Its domain can be available while another company has earlier brand rights. It can also be usable in one country and risky in another.

The useful question is not simply ‘Is this name taken?’ It is ‘What existing names or rights could stop us registering, using or protecting this name in the markets that matter?’ If you are still generating candidates, begin with a broad business-name shortlist, then run every finalist through the same clearance process.

What ‘Taken’ Can Actually Mean

These checks answer different questions. Treating them as interchangeable is how founders end up owning a domain for a name they cannot safely use. Complete the legal-name and trade mark screen first, then apply the broader checks in the domain validation checklist.

Prepare Your Search Before Opening a Database

Write down the exact name, the countries where you expect to trade, and a plain-language description of what you will sell. Trade mark results are assessed in the context of goods and services, so ‘software’ is less useful than ‘subscription software for restaurant inventory management’. Include realistic adjacent products you may launch within the next few years.

• Exact name, with and without spaces, punctuation and company suffixes
• Singular, plural and possessive forms
• Likely misspellings and phonetic equivalents
• The distinctive word or stem without generic terms
• Goods and services sold now, plus realistic adjacent offers
• Launch territories: UK, United States, European Union or another market

Database 1: The Official Legal-Entity Register

For a UK limited company, search the official Companies House register. Search the exact name first, then remove ‘Limited’ or ‘Ltd’ and try the spelling, spacing and sound-alike variants on your worksheet. Open close results and note whether each company is active, dissolved or recently incorporated.

Do not stop when the exact spelling is absent. The current GOV.UK company-name rules explain that punctuation, certain special characters and commonly used company-name words may not make a name different. A complaint can also force action when a new name is considered ‘too like’ an earlier registered name.

In the United States there is no single national company-name register. Search the official entity database for the state where you will form the business, then check any state, county or city office responsible for a DBA or assumed name. The US Small Business Administration’s name guide confirms that entity-name and DBA requirements vary by location and are legally separate from federal trade marks.

Database 2: The UK IPO Trade Marks Register

Use the official UK Intellectual Property Office search for any brand that will trade in the UK. Run the exact phrase, each distinctive word, shortened forms and likely phonetic variants. Review both applications and registrations rather than looking only for an identical registered word mark.

For each close result, read the goods and services specification, owner, filing date and status. The UKIPO advises applicants to search for the same or similar marks and to identify the relevant classes and terms before applying. Its before-you-apply guidance also recommends professional advice when you find a similar mark.

Database 3: The USPTO Federal Trademark Database

For the United States, use the official USPTO Trademark Search system. Begin with the exact wording, then expand to shared terms, alternative spellings, similar pronunciations and the strongest word in a multi-word name. Search each serious candidate consistently so a favourite name does not receive a less rigorous review.

The USPTO’s federal trademark searching guidance says that marks may conflict when they are confusingly similar and their goods or services are related. Similarity can arise from appearance, sound, meaning or overall commercial impression. Related goods do not have to sit in the same international class.

Database 4: EUIPO TMview

If the European Union is a current or planned market, use EUIPO’s TMview guidance and open TMview from the official page. EUIPO states that TMview contains applications and registrations from EU national intellectual-property offices, EUIPO and many participating offices outside the EU.

Repeat the same exact, partial and phonetic searches used for the UK and US. Filter by territory and status only after a broad first pass, then inspect similar signs with similar goods or services. For an EU-wide launch, also consider translations, obvious local spellings and how the name is likely to be pronounced in priority markets. The international brand-name checklist covers the linguistic checks that sit outside registry data.

The Clearance Decision Tree

• Exact legal-entity name unavailable in the place you must register → change the legal name or investigate the jurisdiction’s rules before filing.
• Live or pending similar trade mark plus related goods or services → stop and obtain professional advice before investing in the name.
• Similar mark but the commercial relationship is unclear → mark amber; compare customers, sales channels, purpose and realistic expansion.
• Only dead or inactive records appear → investigate whether the name is still used in commerce; do not treat the record as an automatic green light.
• No material registry conflicts after exact and variant searches → provisional green; continue with web, domain, social-handle and professional checks.

A green result means ‘no obvious conflict found in this preliminary screen’, not ‘legally cleared’. An amber result means the answer depends on facts that a database cannot decide. A red result means the cost of changing direction now is likely lower than building around an unresolved conflict.

What to Check After the Four Databases

Official registers do not contain every trading name or unregistered right. Search the open web, business directories, app stores and relevant marketplaces for active businesses using the exact name or close variants. Then check the matching domain and its history. Our guide to choosing a domain name explains the brand and usability tests that follow legal screening.

Finally, reserve the domain and priority handles only after the shortlist survives the clearance screen. Use the brand protection checklist to secure the remaining surfaces without confusing ownership of a URL or social account with ownership of trade mark rights.

A Repeatable Final Checklist

• Define the exact name, variants, territories and goods or services
• Search the relevant official company or state entity register
• Search UKIPO for exact, partial and phonetic matches
• Search USPTO for similar marks and related goods or services
• Search EUIPO TMview for EU and national-office records
• Log owners, statuses, filing details and commercial overlap
• Escalate every red result and unresolved amber result
• Check unregistered use, domains and social handles
• Re-run all searches immediately before filing or launch
