A WA corporation search lets you find a Washington entity by organization name or Unified Business Identifier, commonly called a UBI number. Start with the Secretary of State's official registry, then review the record carefully before relying on it for a filing or transaction.

Key Takeaways

  • Use the Washington Secretary of State's Corporations and Charities Filing System to search registered entities.
  • You can search by organization name, UBI number, or available advanced filters.
  • LLC lookup, corporation lookup, and company search requests generally lead to the same state registry.
  • A record may show the entity's status, registered agent, governing persons, addresses, important dates, and filing history.
  • No matching results do not guarantee that a proposed business name will be approved.
  • Business entity registration and business licensing are separate issues, and they may require different state lookups.

Official WA Corporation Search: The Fastest Path

For the quickest Washington corporation search, open the official Washington Corporations Search page. The Secretary of State's Corporations and Charities Filing System contains public records for corporations, limited liability companies, nonprofits, and other entities filed with that office.

  1. Choose the business search option in the public filing system.
  2. Enter the organization's legal name, part of its name, or its UBI number.
  3. Use the available name-search setting or filters to control how closely results must match your entry.
  4. Submit the search and review the list of possible matches.
  5. Select the correct entity to open its public record and available filing details.

If a full legal name produces no result, shorten the search. Remove punctuation, entity designators such as LLC or Inc., and words that may have been abbreviated. A business may also operate under a trade name that differs from the entity name filed with the Secretary of State.

Check the UBI number, entity type, address, and record status before concluding that you found the right business. Similar names can belong to unrelated entities, and one organization may have changed its name or filed amendments. If you are looking for an LLC, a corporation, or a Washington company generally, you do not need separate registries for each entity type. The same public system returns multiple types of Secretary of State filings.

How to Run a WA Corporation Search by Name or UBI

The best search method depends on what information you already have. A business name works well for discovery, while a UBI lookup is better for confirming a specific organization. Advanced filters can narrow a long list of similar results.

Search method Information needed Best use Potential limitation
Organization name Full or partial legal name Finding a company or testing a proposed name Similar names and trade names may complicate results
UBI number The entity's nine-digit UBI Confirming an exact entity record A mistyped number may return no useful match
Advanced filters Name plus details such as entity type, status, agent, governing person, or address Narrowing common names or identifying an uncertain match Overly specific or outdated information may exclude the correct record

For a name search, begin with the most distinctive words in the legal name. Capitalization generally should not be your main concern, but spelling and spacing can affect which results appear. Try a broader version if the first search fails.

For a UBI lookup, enter the number associated with the business and confirm that the displayed legal name matches your records. Do not confuse a UBI number with a federal employer identification number. The UBI is Washington's state business identifier, while an EIN is issued for federal tax administration.

Advanced searching is useful when a Washington company search returns many organizations with related names. Add filters gradually so you can see which condition removes a possible match.

What a Washington Business Entity Search Can Show

A Washington business entity search can reveal more than an organization's name. The information available depends on the entity and its filing history, but a public record may include:

  • Legal entity name and UBI number: The official name on the state record and the organization's Washington identifier.
  • Entity type: The form under which the organization is registered, such as an LLC, corporation, or nonprofit.
  • Current record status: The status displayed by the filing system, which may indicate that an entity is active, inactive, or administratively dissolved.
  • Registered agent: The person or business designated in the public filing to receive service of process.
  • Governing persons: Listed members, managers, directors, or other persons identified in state filings.
  • Addresses and dates: Principal office information and dates associated with formation, registration, expiration, or reports.
  • Filing history: Available annual reports, amendments, formation records, and other filed documents.

Treat each field as part of the overall record. A familiar address does not prove that two similarly named organizations are the same entity. Likewise, the registered agent is not necessarily an owner or day-to-day contact.

The search also does not establish every fact about ownership, authority, solvency, licensing, or legal compliance. Public filings reflect information submitted to the state and may not answer questions governed by operating agreements, bylaws, contracts, court orders, or later transactions. If entity structure matters, compare the registry information with the relevant documents.

Using a Washington State UBI Lookup Correctly

A Washington state UBI lookup is usually the most precise way to locate a known business. Washington assigns a Unified Business Identifier to identify the business across participating state agencies. The number can appear on state correspondence, registrations, licenses, tax documents, or filing records.

Enter the UBI in the Secretary of State system when you need the entity record maintained by that office. After opening the result, compare the legal name and entity type with the document from which you obtained the number. This check helps catch transcription errors and situations where paperwork refers to a related organization rather than the contracting entity.

A UBI search does not replace document review. For example, the public record may identify governing persons, but it may not show who has authority to sign a particular agreement. It also may not explain the underlying reason for an inactive or administratively dissolved status. Obtain current filings or appropriate representations when those issues matter.

You cannot obtain a new UBI merely by running a search. A number is assigned through an applicable Washington business registration or licensing process. The proper process depends on how the business is organized and which agencies it must register with. Keep the assigned number consistent on state filings and verify agency instructions before submitting changes.

If similar names create uncertainty, a registry record raises status or ownership concerns, or the search supports a transaction, you can post your legal need on UpCounsel's marketplace. An attorney can review public filings, assess naming or entity-status issues, and prepare or review formation, amendment, or transaction documents. Responses typically arrive within a day, helping you identify what the public record proves and what requires additional documentation.

Checking a Proposed Washington LLC or Corporation Name

A WA state corporation search is a useful first check before filing a new entity, but search results are not a name approval. A proposed name generally must be distinguishable from names already on the Secretary of State's records and must satisfy the requirements for its entity type.

For an LLC lookup in Washington, search the meaningful words in your proposed name without relying only on the LLC designation. An LLC name must use an appropriate limited liability company designation and should not use terms that incorrectly suggest it is a corporation. Changing punctuation, capitalization, grammar, or an entity ending may not make a conflicting name sufficiently distinguishable.

Review exact matches and close variations. Look for alternate spellings, singular and plural versions, abbreviations, and reordered words. If an inactive or administratively dissolved entity appears, do not assume its name is immediately available. Status and name availability are different questions, and the Secretary of State applies the governing name rules when it reviews a filing.

Zero results also do not create a legal right to the name. The database search may not capture every spelling, pending filing, trade name, trademark, or other source of competing rights. Final approval occurs through the state's filing review, and state acceptance does not by itself resolve trademark or unfair-competition issues.

Your entity choice can also affect the name and filing documents. Review Washington requirements for a social purpose corporation or the tax and formation considerations associated with an S corporation in Washington before assuming that an LLC is the right structure. For comparison, a Delaware entity search applies only to Delaware's registry, even if that company also operates in Washington.

Entity Registration vs. Washington Business License Lookup

The Washington Secretary of State business search and a business license lookup serve different purposes. The Secretary of State registry focuses on entities and filings maintained by its Corporations and Charities Division. A record there can confirm that an LLC or corporation was filed, but it does not necessarily establish that the business holds every state, professional, industry, or local license required for its activities.

To look up Washington business license information, use the Washington Department of Revenue's official Business Lookup. That system is the better starting point for state business-license and registration information administered through the Business Licensing Service. Search using the business name, UBI number, or other information requested by the current lookup tool.

Some businesses need endorsements, professional credentials, or regulatory approvals from agencies other than the Department of Revenue. Cities and counties may also impose local licensing requirements. If the activity is regulated, check the agency or local government responsible for that activity rather than relying solely on a corporation record.

The distinction matters during due diligence. An active Secretary of State record does not automatically confirm a current contractor registration, professional license, liquor license, local endorsement, or other specialized authorization. Conversely, the appearance of a business in a licensing system does not answer every question about its entity status or filing history.

Use the UBI number to connect records where possible. Then compare the legal name, location, and entity type to make sure the licensing record belongs to the same business shown in the Secretary of State system.

What to Do After a Washington Corporate Search

Your next step depends on why you conducted the Washington corporate search. If you are verifying another company, save the entity name, UBI number, status, and date of your search. Open relevant filings rather than relying only on the result summary, especially when authority, ownership, or a recent amendment matters.

If the entity is inactive or administratively dissolved, review its filing history and current state instructions. The displayed status may affect a planned contract, financing, merger, qualification, or amendment, but the search result alone does not explain the legal consequences. Ask the entity for current documents and confirm what corrective filing, if any, is required.

If you are choosing a new name, prepare alternatives before filing. Search each alternative broadly, check relevant trade names and trademarks separately, and wait for state review rather than treating an empty result page as approval. Avoid committing substantial resources to branding when a close conflict remains unresolved.

The filing system may also allow you to obtain official records. Depending on your needs, these can include a Certificate of Existence, certified copies of filings, formation documents, amendments, annual reports, or historical records. Banks, investors, transaction parties, and government agencies may request a specific document, so confirm what they require before ordering it.

A Certificate of Existence addresses the entity's standing as reflected by the issuing office. It is not a substitute for reviewing contracts, ownership documents, licenses, tax matters, liens, litigation, or other transaction risks. Match the scope of your follow-up work to the decision you are making.

Frequently Asked Questions

How Do I Look Up an LLC in Washington State?

Search the Washington Secretary of State's Corporations and Charities Filing System using the LLC's legal name or UBI number. If several records appear, compare the entity type, principal address, formation date, and registered agent. A trade name may not match the LLC's legal name, so search shortened or alternate versions when necessary.

How Do I Look Up a Business in Washington State?

Start with the state system that matches the information you need. Use the Secretary of State registry for entity filings and the Department of Revenue's Business Lookup for state business-license information. For a regulated profession or local activity, also check the licensing agency, city, or county responsible for that authorization.

How Do I Get a UBI Number in Washington State?

You receive a UBI number through an applicable Washington registration or business-licensing process, not through the public search tool. The correct application path depends on your entity and activities. Follow the current instructions from the Secretary of State, Department of Revenue, or other responsible agency, then retain the assigned number for future state filings.

How Can I Find Business Registration Information?

Use the business's legal name or UBI number to identify its state record, then open the available details and filings. For a transaction, request copies directly from the business as well. Internal governance documents and contracts may contain registration-related information that does not appear in the public database.

How Do I Look Up a Business License in Washington State?

Use the Washington Department of Revenue's Business Lookup to check information maintained through the state's Business Licensing Service. A separate regulator may oversee professional or industry-specific licenses, and a city or county may maintain local endorsements. Confirm the business's UBI and location before treating a licensing result as a match.

Does an Inactive Washington Entity Mean Its Name Is Available?

No, an inactive status does not automatically make the entity's name available for a new filing. Name availability depends on Washington's current rules and the records considered during filing review. Submit alternative names if a close match exists, and avoid assuming that administrative dissolution, expiration, or inactivity eliminates all naming or trademark concerns.
