Washington Business Name Search: How to Check and Reserve a Name

Choosing a business name is one of the first and most important decisions you'll make as an entrepreneur. Before you get attached to that name, you need to know if it's actually available in Washington. This guide walks you through the Washington business entity search process and shows you how to reserve your name while you complete the rest of your formation work.

What You Need Before Starting

The good news: searching for a business name in Washington is free and straightforward. You'll need:

• A web browser (Chrome, Firefox, Safari, or Edge)
• Your desired business name (have 2 to 3 backup options ready)
• A credit card or debit card if you want to reserve the name (name reservation costs $30)
• The business structure type you're considering (LLC, corporation, partnership, etc.)
• 10 to 15 minutes of your time

That's it. The Washington Secretary of State offers both a free search tool and a simple online reservation system. No appointments needed, no paperwork to mail.

Understanding Washington Name Requirements

Before you search, it helps to know the rules. Under Washington law (RCW 23.95.305), your business name must:

• Include a legal designator if you're forming an LLC, corporation, partnership, or similar entity. For an LLC, this means the name must contain "Limited Liability Company," "Limited Liability Co.," "L.L.C.," or "LLC." For a corporation, use "Corporation," "Corp.," "Incorporated," "Inc.," "Company," or "Co."
• Be distinguishable from every other business name already on file with the Washington Secretary of State. "Distinguishable" means customers shouldn't confuse your business with another one.
• Not contain certain restricted words unless you meet specific conditions. Banned words include: bank, banking, banker, trust, cooperative, and certain combinations involving building, savings, loan, home, association, industrial, and society.

Restrictions on restricted words exist because they imply you offer regulated services (banking, credit unions) that require special licensing. Using them without proper authorization is illegal.

Step-by-Step: How to Search Your Business Name

Step 1: Navigate to the Washington Business Search Database

Go to the Washington Secretary of State's business search portal at https://ccfs.sos.wa.gov/#/BusinessSearch. This is the official, authoritative database for every business entity registered in Washington. The page loads quickly, and the search box appears at the top of the screen.

Step 2: Enter Your Desired Business Name

Type your proposed business name into the search box. You can search for the exact name or use partial keywords. For example, if you want to name your company "Pacific Northwest Coffee Roasters LLC," you could search "Pacific Northwest Coffee" or just "Coffee Roasters." The system searches across all registered entities: LLCs, corporations, limited partnerships, and more.

Do not include the LLC/Corporation designator when you search. Search for "Cascade Digital" not "Cascade Digital LLC." The search tool is smart enough to ignore the legal suffix.

Step 3: Review the Search Results

The database will display any matching names. Look carefully at each result. You're checking for two things:

1. Exact or very similar matches. If a name already exists that's confusingly similar to yours, the Secretary of State will likely reject your filing. Examples: your name is "Emerald Tech Solutions" and "Emerald Technical Solutions LLC" is already registered. The Secretary of State may see these as too similar and deny your application.
2. Inactive or dissolved businesses. The search results show whether a business is active or dissolved. A dissolved business name may eventually become available, but it is not available for you to register today. Wait until the name is truly removed from the system, or choose a different name.

Click on any result that interests you to see more details: business address, formation date, and current status. This helps you understand whether the name conflict is real.

Step 4: If Your Name Is Available, Proceed to Reservation

If your search returns no matches or only very different names, your desired name is likely available. Now you have two choices:

1. File your business formation documents immediately. If you're ready to formally create your LLC or corporation, you can skip the reservation step and file directly. Your name is protected once your formation documents are accepted by the Secretary of State.
2. Reserve the name for later. If you want to secure the name while you plan your business, work on a business plan, or arrange financing, you can reserve it for 180 days.

Step-by-Step: How to Reserve a Business Name in Washington

Step 1: Access the Reservation Filing System

Visit the Corporations and Charities Filing System (CCFS) at https://ccfs.sos.wa.gov/. This is the same portal where businesses file formation documents. Look for the option to file a "Name Reservation Application" or "Name Reservation." The option appears clearly in the filing menu.

Step 2: Choose Your Entity Type (Optional)

You'll be asked what type of business you plan to form. Options include LLC, corporation, partnership, and others. You don't need to have made a final decision; this is just to ensure your name is reserved under the right category. Most business owners reserve names for LLCs, so if you're still deciding between an LLC and a corporation, you can reserve the name as an LLC and refile when you form the actual entity.

Step 3: Enter Your Business Name

Type in the exact name you want to reserve. Remember: include the legal designator if you're reserving an LLC name. Example: "Soundwave Audio Design LLC." The system will check the database one more time to ensure the name hasn't been claimed in the seconds since you last checked. The database is live, so another business owner could theoretically file before you do.

Step 4: Provide Your Contact Information

You'll enter your name, address, and email. This is the information the Secretary of State will use to contact you if there's an issue with your reservation. Make sure your email is current and monitored regularly.

Step 5: Pay the Reservation Fee

The name reservation fee is $30. The CCFS system accepts credit cards and debit cards online. Processing is immediate. Once you complete payment, your reservation is active.

Step 6: Confirm Your Reservation

You'll receive a confirmation page with your reservation number and the date the reservation expires (180 days from filing). Save or print this confirmation. You may need the reservation number when you file your actual formation documents.

How Long Does This Take?

The Washington business name search itself is instant. The search database returns results in seconds. Filing a name reservation takes about 5 to 10 minutes online, including payment processing. Your reservation is active immediately upon approval.

If you need your name reservation processed faster, the Secretary of State offers expedited service for $100, with a standard turnaround of three business days. For most business owners, standard processing is fast enough.

Common Mistakes to Avoid

Mistake 1: Not Searching Thoroughly Enough

Search your name multiple ways. Try the exact name, variations, abbreviations, and related keywords. Someone might have registered "Pacific Northwest Coffee Roasting" when you planned to use "Pacific Northwest Coffee Roasters." These are close enough that the Secretary of State might reject your filing as too similar. A thorough search catches these issues before you pay filing fees.

Mistake 2: Forgetting the Legal Designator

Your LLC name MUST include LLC (or Limited Liability Company, L.L.C., Limited Liability Co.). A filing without it will be rejected. Similarly, corporations must include Corp., Corporation, Inc., Incorporated, Company, or Co. The Secretary of State requires this designation. Do not submit a formation document for "Cascade Digital" if you're forming an LLC; it must be "Cascade Digital LLC."

Mistake 3: Assuming Your Domain Name or Social Media Handle Means Your Business Name Is Available

Just because you can register the domain cascadedigital.com or @cascadedigital on Instagram does not mean the business name is available in Washington. Domain registrars and social platforms have different rules and databases than the Washington Secretary of State. Always search the Secretary of State database directly.

Mistake 4: Relying on an Expired Reservation

A name reservation lasts 180 days. If you don't file your formation documents within that window, your reservation expires and the name becomes available to others. Set a calendar reminder for day 150 of your reservation period so you know when to file your formation documents or renew your reservation.

Mistake 5: Using Restricted Words Without Checking First

If your name includes bank, trust, loan, or similar restricted words, verify that you meet the exception requirements before you file. The Secretary of State will reject your filing if you use restricted words without proper authorization. This is a filing error that wastes time and your filing fee.

Tips for Choosing a Name That Will Be Approved

• Make it distinctive. The more unique your name, the less likely another business has already claimed it. Avoid generic names like "Seattle Web Design" or "Washington Consulting Group."
• Check trademark databases too. While not required by Washington, a federal trademark search at the U.S. Patent and Trademark Office can alert you to potential conflicts outside the state. This prevents legal problems later.
• Avoid hard-to-spell or confusing names. A name that's easy to spell, pronounce, and remember will serve your business better as you market it.
• Reserve early if you're not ready to file. If you've found a great name but you're still in the planning phase, reserve it for $30 now. It's a small investment to protect your choice.

What Happens After You Reserve or File Your Name?

Once your name reservation or formation filing is accepted, your name is protected in Washington. No other business can register the same name or a name the Secretary of State deems too similar. This protection exists as long as you maintain your business with the state (through annual reports and timely filings).

If you reserve the name but then file formation documents, your reservation is fulfilled and the reservation period ends. Your business is now officially registered, and the name remains protected indefinitely (assuming you stay compliant with state filing requirements).

Next Steps

• Filing your formation documents (Certificate of Formation for an LLC, Articles of Incorporation for a corporation)
• Obtaining an Employer Identification Number (EIN) from the IRS
• Applying for a Washington State Business License if required for your industry
• Opening a business bank account
