First decide whether you need to register a legal entity name, a trade or “doing business as” name, or a trademark. Those are different filings, and none is a substitute for checking the official rules in your jurisdiction.
1. Identify which name or right you need to register
“Business name” can refer to several different things. A filing may record the legal name of a company, the name a business uses publicly, or a brand that you want trademark protection for. A domain name is a web address, not a business registration.
- Entity name: The legal name of a company or other registered entity. Forming the entity and registering its name may be part of the same process, depending on the jurisdiction.
- Trade name or DBA: A name used to do business that differs from the owner’s or entity’s legal name. Depending on location, it may be called an assumed, fictitious, or trade name. Filing rules differ, and registration does not itself provide trademark protection.
- Trademark: A separate filing for brand protection. Its rights and geographic scope are different from a business-name registration.
- Domain name: The address used for a website. Registering one does not register a company or establish trademark rights.
The U.S. Small Business Administration distinguishes these registrations and explains that a DBA may be required by a state, county, or city without providing legal protection by itself. See SBA guidance on launching a business.
2. How to register a business name
- Choose your jurisdiction and structure. Identify where the business will operate and whether it will be a sole proprietorship, partnership, LLC, corporation, or local equivalent. The appropriate filing office and requirements can depend on both.
- Decide which filing applies. If you are forming an entity, check how to register its legal name. If you will trade under a different name, find out whether a separate trade-name or DBA filing is required. If you want brand protection, investigate trademark registration separately.
- Search official records. Search the relevant government company or business-name register and the trademark database for the market where you intend to operate. A registry search is an initial screen—not confirmation that a name is legally safe to use or that you have exclusive rights to it.
- Check naming rules and prerequisites. Authorities may restrict identical or confusingly similar names, require particular legal suffixes, or limit sensitive words and names that suggest a government connection. Some processes also require an identifier or other step before you apply.
- Apply through the official authority and pay its current fee. Use the government registry for your jurisdiction rather than assuming that a third-party filing service is necessary. Confirm the application route, documents, and amount directly with that authority.
- Check what remains after the filing. Name registration may not complete entity formation, tax registration, licensing, permitting, or reporting obligations. Check those requirements separately.
3. What the process looks like in different countries
These official examples illustrate why instructions from one country should not be treated as universal. The exact requirements and current fees should be confirmed with the responsible registry.
#1 Best Overall
United States
The SBA describes entity-name registration as generally handled at the state level. DBA requirements can be set by a state, county, or city. A person doing business under their own legal name may not need a separate business-name filing, but other obligations can still apply. Filing fees vary by state and business structure; local licensing and permitting rules may also apply. Trademark registration and domain registration are separate matters. Start with the SBA’s launch guidance and follow its links to the relevant state or local authority.
Australia
Australia registers business names nationally rather than through separate state or territory name registries. The government directs applicants to choose a business structure, obtain an Australian Business Number (ABN), check the business-name register, and search for possible trademark conflicts through IP Australia. Its application process uses ASIC Connect or the Business Registration Service; ASIC’s instructions call for an ABN or an ABN application, the proposed name, and payment. See business.gov.au’s registration guide and ASIC’s application steps.

United Kingdom
The cited GOV.UK rules apply to private limited companies, not automatically to sole traders or partnerships. A limited company name cannot be the same as another registered company’s name, and a name that is too similar may be challenged. Company names usually need “Limited” or “Ltd”; Welsh alternatives may apply to a company registered in Wales. Sensitive words or wording that suggests a government connection can require permission. A company trading under a different business name must also follow restrictions, including limits on company-form suffixes and sensitive wording. See GOV.UK’s company-name rules.
Canada
According to the federal guide, a sole proprietor using their own legal name generally does not need to register a separate business name. Incorporating includes corporate-name registration in the jurisdiction where the corporation is formed. Trade-name registration is handled provincially or territorially, so the correct registry depends on where the business operates. Registering a business name does not replace trademark registration. See the Government of Canada’s guide to registering a business name.
4. How to check whether a name is available
Use the official business or company register for the place where you plan to register, then search relevant trademark records for your intended market. Australia’s government, for example, directs applicants to check both ASIC’s business-name register and IP Australia’s trademark search.
These searches answer different questions. A business registry can indicate whether a proposed name meets that registry’s rules, while a trademark search helps identify potentially conflicting brand rights. Neither search alone guarantees that you can use a name without legal risk. If the brand is important to the business, consider getting advice from a qualified trademark professional.

There is no standard fee that applies everywhere. Costs depend on the jurisdiction and the type of filing, and in the United States they vary by state and business structure. Check the official registry for the current fee, any renewal or reporting requirements, and the documents or identifiers needed to apply; the sources cited here do not establish one comparable fee across countries.
Also check whether the name filing is separate from forming the business entity, registering for taxes, or obtaining local licenses and permits. A name filing records a particular name under a particular system—it does not by itself complete every step needed to operate.
