What is an assumed name?

An assumed name is a name a business entity operates under that differs from its legal name, such as a company registered as "Northstar Services LLC" that sells as "BrightPath Consulting." States also call it a DBA ("doing business as"), a trade name or a fictitious name.

Many teams treat the brand on the website as if it were the company. The brand is only a label on an existing entity. The filing that registers it is a public notice. The Texas Secretary of State says an assumed name certificate "provides information about the underlying business's identity and location" (Texas name filings FAQ). Its Form 503 instructions list a $25 filing fee and a term of up to 10 years. A company that runs several brands through several entities across several states has a separate filing for each combination of brand, entity and state. Each of those filings has its own office, fee and term.

What is an assumed name?

An assumed name is a registered alias for a person or entity that already exists. It differs from the legal entity name on formation documents and state filings.

The registration creates nothing new. Pennsylvania's Department of State says "The use of a fictitious name does not create a separate legal entity" and "Registration of a fictitious name does not provide liability protection" (Pennsylvania fictitious names). Vermont's Secretary of State says the same thing: "An assumed business name registration does not create a legal business entity," and registrants "incur the same liabilities as would doing business in the individual name(s) of the registrants(s)" (Vermont assumed names).

For legal and finance teams, this means contracts, debts, tax filings and lawsuits under the brand belong to the LLC or corporation behind it. Every obligation tracks back to that one entity.

How an assumed name differs from a legal entity name

The legal name is the name in the entity's certificate of formation, while an assumed name is a brand the entity operates under. In most states the legal name carries a designator that the statute requires for the entity type. In Texas, a corporation's name must contain "company," "corporation," "incorporated" or "limited," or an abbreviation of one of them, under the Business Organizations Code (§5.054). An LLC's name must contain "limited liability company" or "limited company," or an abbreviation (§5.056).

Some states keep entity designators out of the assumed name. Formation creates the entity's legal identity. The assumed name certificate only publishes a link between that identity and a second name.

The legal name stays on the state's own paperwork. Texas Form 503 requires the entity's legal name "as currently shown in the records of the secretary of state or on its organizational documents" (Texas Form 503). New York requires the name on the certificate to exactly match Department of State records (New York LLC certificate). Annual reports, foreign registrations and the assumed name certificate itself all run on the legal name. A record that holds only the brand cannot drive any of those filings.

When an entity uses an assumed name

Entities use assumed names to brand product lines or locations, open bank accounts under brand names and run multiple brands through one LLC.

In Texas, the rule covers a corporation, LLC, limited partnership, LLP or foreign filing entity that "regularly conducts business or renders a professional service" under a name other than its legal name (Tex. Bus. & Com. Code §71.103, as stated in the Form 503 instructions). New York's Department of State says corporations, limited partnerships and LLCs "are required by statute to conduct activities under their true legal name" unless they file a certificate under General Business Law (GBL) §130 (New York DOS FAQ).

Branding a product line or location

A common trigger is a consumer-facing brand that differs from the registered name. The SBA glossary gives "Bob's Burgers" used in place of the legal name Blocker & Sons LLC (SBA glossary).

Shortening the legal name can trigger a filing too. Minnesota's Secretary of State uses "St. Paul Painting Contractors, Inc." operating as "St. Paul Painting" as its example of a filing it requires (Minnesota assumed names).

Locations add their own work. In New York, General Business Law §130(4) requires a certified copy of the filing to be displayed on the premises where business is conducted under the assumed name, at $10 per certified copy (New York instructions).

Opening a bank account under the brand name

Banks often ask for the filed certificate before they open an account or accept payments in the brand's name. Requirements differ by bank:

• Wells Fargo: A fictitious name statement or similar document is required if the business operates under another name (Wells Fargo FAQ).

• Bank of America: If it cannot verify an LLC's business, the bank may request one of several documents for an LLC operating under a different name, such as a Certificate of Assumed Business Name or Trade Name Certificate. The bank does not require these documents in Kansas, New Mexico or South Carolina (Bank of America requirements).

• U.S. Bank: Its application checklist requires proof of the legal name when the applicant uses a DBA name (U.S. Bank checklist).

In practice, the certificate needs to be filed and in hand before the account-opening call, along with the formation documents.

Running multiple brands from one LLC

Take one hypothetical LLC, Northstar Services LLC, running three brands in Texas and New York:

1. Texas: The LLC files three Form 503 certificates with the Secretary of State, one per brand. At $25 each, that comes to $75.

2. New York: The LLC files three Certificates of Assumed Name with the Department of State at $25 each, another $75. New York charges LLCs no county fee.

3. Total: $150 in state filing fees for six filings. New York certified copies for display at each location cost extra.

Contracts and invoices should name the LLC first and the brand second. A signature block in that format reads:

Northstar Services LLC d/b/a BrightPath Consulting By: Jordan Lee Title: Manager

Filing an assumed name certificate: who files and where

In many states, entities file assumed names with a central state office, but some route entity filings to counties or to agencies other than the Secretary of State. The filing office, fee, publication step and term all depend on the state, so each one needs checking before filing.

Which entities file

LLCs, corporations, limited partnerships and LLPs file when they use a name other than their legal name. The Texas Form 503 checklist lists for-profit corporations, LLCs, nonprofit corporations, limited partnerships, professional corporations, LLPs, professional associations and cooperative associations. New York's statute separates corporations, limited partnerships and LLCs, which file with the Secretary of State, from everyone else (GBL §130). Sole proprietors and general partnerships usually file with a county clerk instead, as they do in both Texas and New York.

Choosing the state or county filing office

The office depends on the state, and sometimes on the entity type:

• Secretary of State or equivalent: Texas, New York, Florida, Minnesota and Pennsylvania take entity filings centrally. Texas dropped the county filing requirement for entities in House Bill 3609, effective September 1, 2019.

• A state agency other than the Secretary of State: Washington registers trade names through the Department of Revenue's Business Licensing Service (Washington trade names). Delaware moved trade names to the Division of Revenue as of February 2, 2026 (Delaware Division of Corporations). Virginia's State Corporation Commission has been the central office since January 1, 2020 (Virginia SCC instructions).

• County, even for entities: California requires every registrant, entities included, to file a fictitious business name statement with the clerk of the county of its principal place of business (Cal. BPC §17915). Nevada requires a certificate with the county clerk of each county where business is conducted (NRS 602.010). North Carolina uses the register of deeds, and a business operating in several counties files in only one (G.S. 66-71.4).

• Both levels: Arkansas requires corporations to file with the Secretary of State. A domestic corporation also files with the county clerk where its registered office sits, unless that office is in Pulaski County (Doing Business in Arkansas).

Some states add newspaper publication for entity filings, including California, Florida, Georgia (O.C.G.A. §10-1-490), Minnesota and Nebraska (Nebraska trade name publication). Illinois requires publication only for individuals and partnerships filing with a county clerk; its Assumed Business Name Act does not apply to corporations, LLCs, LPs or LLPs (805 ILCS 405). In California, the statement must be published within 45 days of filing, once a week for four successive weeks. An affidavit of publication must then be filed with the county clerk within 45 days after publication ends (Cal. BPC §17917; Cal. Gov. Code §6064). Minnesota requires publication in a qualified newspaper for two successive issues (Minn. Stat. §333.01). Pennsylvania requires advertising only when an individual is a party to the registration, so a filing by an entity alone skips that step. Our DBA filing guide covers office, fee and publication rules state by state.

Checking name availability before filing

Texas does not check assumed names for conflicts, and Minnesota does not check them against other assumed names (Minnesota naming guidance), so either office may accept a name that someone else already uses. Minnesota does still reject an assumed name that is not distinguishable from an entity name or registered mark on file (Minn. Stat. §333.055). Texas says Chapter 71 "does not authorize rejection of an assumed name certificate on the basis of a name conflict," so "there may be multiple assumed name certificates on file with the secretary of state for the exact same name."

State databases are still the first place to look. New York's database "includes assumed name filings for corporations, limited liability companies and limited partnerships," but the Department warns that "This system should not be used to determine the acceptability of an Entity Name" (New York entity database).

Texas launched SOSPortal on September 29, 2026, replacing SOSDirect and SOSUpload (Texas SOSPortal announcement). The Secretary of State charges $1.00 per entity search (SOSPortal instructions).

Naming rules can lead to a rejected filing:

• Designators: New York says an assumed name cannot contain "Corporation," "Incorporated," "Limited," "Limited Liability Company," "Limited Partnership" or their abbreviations. Florida bars an entity suffix such as Inc. or LLC unless at least one registrant is an entity of that type (Florida filing instructions).

• Restricted words: New York permits certain words only with consents or approvals, and its instructions point to Business Corporation Law §301 and LLC Law §204 for the lists. In Texas, words such as "Bank" and "Trust" require a letter of no objection from the Banking Commissioner, with a $100 fee and no guarantee of approval (Texas formation FAQ).

• The legal name itself: Texas rejects a certificate whose assumed name is exactly the entity's legal name, because that is not an assumed name under Chapter 71.

Two examples: Texas and New York

Texas and New York both handle entity filings centrally and charge the same $25 base fee, but New York adds county fees for corporations, and the two states treat terms and changes differently. Here is how they compare:

Forms, fees and terms change, so confirm both states against the official sites before filing. For any other state, use the DBA filing guide instead of the two examples here.

Renewing, amending and cancelling a filing

An assumed name filing has to be renewed, amended when its facts change and cancelled when the brand is retired, on terms that vary by state. In Texas, a certificate is void at the end of its stated term unless the registrant files a renewal certificate within the six months before expiration (Tex. Bus. & Com. Code §71.151(b)). In New York, §130(3) requires an amended certificate within thirty days after the facts on file change, such as the entity's name, address or counties (New York amendment form).

Terms differ widely by state:

• Florida: Registrations run five years and expire December 31 of the fifth year (Florida fictitious names).

• Minnesota: Assumed names require an annual renewal, and the state charges no fee for it (Minn. Stat. §333.055).

• Oregon: Registrations renew every two years, within 30 days before each second anniversary (ORS 648.017).

• California: Statements expire after five years, or 40 days after a change in the filed facts (Cal. BPC §17920).

• Washington: A trade name stays registered until the owner cancels it.

When a brand is retired, the entity files Form 504 in Texas (Form 504 instructions) or a Certificate of Discontinuance in New York (New York discontinuance form). A team with 20 brands across 10 states may be tracking terms of one, two, five and ten years, plus filings with no expiration at all, each on a different calendar from the entity's annual report.

Common issues and pitfalls

Common problems with assumed names come from treating the certificate as something it is not: a liability shield, an exclusive right or a one-time task.

Expecting an assumed name to protect personal assets

An assumed name adds no protection. As Pennsylvania and Vermont state, it creates no entity, so liability stays with the LLC or corporation behind the brand, or with the individual if no entity exists. Whatever protection the business has comes from its entity, and from contracts that name that entity as the party.

Assuming the name is yours alone

In most states, an assumed name filing does not reserve the name. Florida's Division of Corporations says registration does not "Prohibit someone else from using or registering the same fictitious name." Pennsylvania says "Other individuals or entities may register the same fictitious name." North Dakota is an exception. Its trade name statute requires each trade name to be distinguishable from other trade names on file (N.D.C.C. §47-25-03), and the Secretary of State says registration "Grants the owner exclusive right to that name in the State of North Dakota" (North Dakota Secretary of State). Ohio also grants exclusive rights to registered trade names (Ohio name availability guide). Brand protection beyond one state comes from trademark law, covered below.

Operating without filing

In many states, an entity can lose access to the courts until it meets the state's filing and publication requirements. In Texas, a person that has not filed "may not maintain in a court of this state an action or proceeding arising out of a contract or act in which an assumed name was used until an original, new, or renewed certificate has been filed" (§71.201(a)). The same subsection says the failure does not impair the validity of contracts. An intentional violation is a Class A misdemeanor (§71.202).

New York's §130(9) makes knowing noncompliance a misdemeanor and bars actions on contracts made under the unfiled name until the certificate is filed. California (BPC §17918) and Florida (§865.09(9)(a)) bar suits until the business complies.

Letting a registration lapse

A lapsed registration can mean starting over. Florida says an expired fictitious name "can not be renewed or reinstated," so a new registration must be filed (Florida renewal instructions). Some states allow a recovery. Minnesota revives an expired certificate when the annual renewal is filed with a $25 fee (Minn. Stat. §333.055), and Oregon allows reactivation within five years of administrative cancellation (ORS 648.018).

Renewals tend to slip because assumed name terms run outside the annual report calendar.

Types of assumed name labels by state

States use different labels for the same filing. The label usually names the form and statute in that state, and nothing more.

DBA (doing business as)

DBA is the informal label many states use alongside their official term. In Texas, where the official term is assumed name, the Secretary of State says it is often referred to as a "dba." New York's Department of State describes an assumed name as "commonly referred to as a D/B/A" (New York DBA page). Missouri's official term is fictitious name, which it says is "commonly referred to as a 'DBA'" (Missouri fictitious name FAQ).

Trade name

Washington, Colorado and Georgia use "trade name." Washington registers trade names under RCW 19.80 through the Department of Revenue. Colorado defines a trade name as "an assumed name used to identify the business or activities of an individual or organization" (Colorado trade name FAQ). Georgia registers trade names with the clerk of superior court, not the Secretary of State (O.C.G.A. §10-1-490). Ohio uses both terms and distinguishes them, treating fictitious names as names not distinctive enough to qualify as trade names.

Fictitious business name

California uses "fictitious business name" in Business and Professions Code §17900 and following. Florida uses "fictitious name" under its Fictitious Name Act, which defines it as "any name under which a person transacts business in this state, other than the person's legal name" (Fla. Stat. §865.09). Pennsylvania also uses "fictitious name," and Oregon uses "assumed business name."

Related concepts

An assumed name is easy to confuse with the two other names a company holds: its legal name and its trademarks. Our DBA vs LLC comparison covers the assumed name and entity question in more depth.

Assumed name vs trademark

The USPTO separates the two by where each is registered. "You register your trade names with your state to conduct business there," while "You register trademarks with the United States Patent and Trademark Office to secure nationwide ownership rights" (USPTO trade name flyer). The three names compare as follows:

Trademark registration is a separate process with its own counsel and costs, and it does not replace the state assumed name filing.

File and renew assumed names across every entity with Discern

Each combination of brand, entity and state is its own filing, with its own office, fee, publication rule and term. A Texas certificate can run 10 years. A Minnesota name needs renewing every year. A New York corporation pays county fees that an LLC does not. Discern's DBA filing service files all state-level DBAs, plus county and local filings where possible, and stores the filing evidence in each entity's record. Customers are notified when a DBA is due for renewal and file the renewal through Discern.

The DBA service runs on the same system of record that holds legal names, jurisdictions, registrations and filing history, so the legal name on each certificate comes from the record the annual reports use. Casco, which operates under a name that differs from its legal entity name, used Discern from July 2026 to register that name across ten states. In Florida, Casco first needed a foreign registration, filed August 7, before its DBA could go in; the DBA was filed August 13, six days later.

FAQs about assumed names

These answers summarize the filing-level rules above. Confirm details for a specific state against its official sources.

Do entities file assumed names with the state or the county?

It depends on the state. Texas, New York, Florida and Minnesota take entity filings centrally. California, Nevada and North Carolina send entity filings to a county office, and Arkansas requires some corporations to file at both levels.

Does an assumed name protect personal assets?

No. Pennsylvania and Vermont both state that an assumed name creates no separate legal entity, and Pennsylvania says registration "does not provide liability protection." Any protection comes from the LLC or corporation behind the name.

Can someone else register the same assumed name?

Yes, in most states. Texas allows multiple certificates for the exact same name, and Florida says registration does not prevent anyone else from registering the same name. North Dakota is an exception and grants in-state exclusivity for registered trade names. Ohio's registered trade names also carry exclusive rights.

How do I search Secretary of State records for existing assumed names?

Start with the state's entity database. New York's entity database covers assumed name filings for corporations, LLCs and LPs but warns against using it to judge whether a name is acceptable. Texas SOSPortal charges $1.00 per search unless an order is placed from the results, and county records for sole proprietors are kept separately.

How long does an assumed name registration last?

It depends on the state. Texas allows up to 10 years with renewal in the final six months. Florida runs five years, Oregon two, Minnesota requires an annual renewal, and Washington trade names stay registered until cancelled.

What happens if an entity operates under an unfiled assumed name?

In many states, it is barred from suing until it files the certificate and completes any required publication. Texas, New York, California and Florida all bar lawsuits on contracts made under an unfiled name until the business complies. Texas and New York also treat intentional or knowing violations as misdemeanors.
