Official Sources for Business Information in Washington State

When conducting a Washington State business lookup, always prioritize official government sources. These databases are the most accurate and up-to-date for legal registration and licensing information.

Washington Secretary of State (SOS) Business Search

The Washington Secretary of State's Corporations and Charities Filing System (CCFS) is your primary go-to for verifying the legal existence and status of most business entities in Washington.

What You Can Find Here:

  • Business Name & Type: Verify the official registered name and legal structure (e.g., LLC, Corporation, Non-profit, Limited Partnership).
  • Unified Business Identifier (UBI): This is a crucial 9-digit number assigned to businesses registered in Washington State, used across multiple state agencies.
  • Current Status: Is the business active, inactive, or dissolved? This is critical information.
  • Principal Office Address: The main mailing address on file.
  • Registered Agent Information: The individual or entity designated to receive legal documents on behalf of the business.
  • Filing History: Access to past filings and documents, though some detailed documents may require a fee.

How to Use the SOS Search Tool:

  1. Navigate to the Washington Secretary of State's Corporations and Charities Filing System (CCFS) website.
  2. Look for the "Corporation Search" section. You can typically search by business name or UBI number.
  3. For more refined results, utilize the "Advanced Search" options, which may allow filtering by business type, status, or even registered agent.
  4. Once you find the business, click on its name or UBI to view detailed information.

Washington State Department of Revenue (DOR) Business Lookup

The Department of Revenue's Business Lookup tool is essential for finding information related to business licenses, tax accounts, and reseller permits.

What You Can Find Here:

  • Business Name & Trade Name: Both the legal name and any "doing business as" (DBA) names.
  • UBI Number: Another place to verify the Unified Business Identifier.
  • Business License Information: Details on state and city endorsements obtained through the Business Licensing Service.
  • Owners and Officers: Publicly available information on key personnel.
  • Address and Contact Information: Street address and other contact details.

How to Use the DOR Business Lookup:

  1. Visit the Washington Department of Revenue's website and look for their "Business Lookup" tool.
  2. You can search by business name, trade name, UBI, or even address.
  3. The lookup provides public information for current active accounts and five years of closed accounts.

Washington State Department of Labor & Industries (L&I) Verify Tool

If you're looking to hire a contractor or tradesperson, or want to check a business's compliance with labor laws, the L&I Verify tool is invaluable.

What You Can Find Here:

  • Contractor Registration Status: Is the contractor actively registered and licensed?
  • Workers' Compensation Account Status: Do they have an active and paid-to-date workers' comp account for their employees?
  • Safety & Health Violations: Information on any citations or violations related to workplace safety.
  • Lawsuits Against Bond: Details on any legal actions against their surety bond.
  • Business Owner Names: Confirmation of the names of business owners.

How to Use the L&I Verify Tool:

  2. Locate their "Verify a Contractor, Tradesperson or Business" tool.
  3. Enter the business or contractor's name to check their registration and compliance details.

Leveraging Online Directories and Databases

While official government sites are the most authoritative, other online resources can supplement your business search tips for Washington State, especially for finding local businesses or specific services.

  • Google Maps & Google Business Profile: For local businesses, Google Maps often provides business hours, reviews, photos, contact information, and website links. Businesses with a verified Google Business Profile offer more comprehensive details.
  • Yelp, TripAdvisor, and other Review Sites: These platforms are excellent for consumer reviews, photos, and general business information, though always consider the source and potential for bias.
  • Industry-Specific Directories: Many industries have their own professional associations or directories (e.g., bar associations for lawyers, real estate boards for brokers). These can be great for verifying professional licenses and specializations.
  • Chamber of Commerce Websites: Local Chambers of Commerce often list member businesses, providing another avenue for discovery and networking.

Advanced Business Search Strategies

Sometimes, a simple name search isn't enough. Here are some advanced business search tips for Washington State to dig deeper:

  • Utilize UBI Numbers: If you have a UBI number, it's often the quickest and most accurate way to find a business across different state agency databases.
  • Refine Search Terms: When using general search engines, be specific. Instead of just "plumber Seattle," try "licensed plumber Seattle" or "Seattle plumbing contractor license."
  • Reverse Lookups: If you have an address or phone number, some online tools or even a direct call to a city's business licensing department might help you identify the associated business.
  • Public Records Requests: For information not readily available online, you might need to submit a formal public records request to the relevant state or local agency. Be aware that some business information, especially tax-related data, is confidential.

Tips for Effective Searching

To ensure your business search tips for Washington State are as effective as possible, keep these pointers in mind:

  • Be Specific: The more precise your search terms (e.g., full business name, city, UBI), the better your results will be.
  • Check Multiple Sources: Don't rely on just one website. Cross-referencing information across the SOS, DOR, and L&I can provide a more complete picture.
  • Understand UBI Numbers: Remember that the Unified Business Identifier (UBI) is a unique 9-digit number that acts as a central identifier for businesses across various Washington State agencies. It's assigned when a business registers with agencies like the Department of Revenue, Department of Employment Security, Department of Labor and Industries, or the Secretary of State.
  • Verify Information: Publicly available information can change. Always check the "last updated" date on official records and, if necessary, contact the agency directly for the most current data.
  • Be Aware of Confidentiality: While much business information is public, certain details, particularly financial or highly sensitive data, are protected by law.

Conclusion

Navigating the world of business information in Washington State doesn't have to be a daunting task. By utilizing the official resources provided by the Washington Secretary of State, Department of Revenue, and Labor & Industries, along with smart search strategies, you can confidently find the information you need.
