5. How to Reserve a Business Name in Washington, D.C.

If you’ve picked a great name for your business and want to make sure no one else grabs it, you can reserve it in advance through the CorpOnline portal.

Here’s how:

1. Log in to your Access DC account.
   
   
2. Navigate to the "Name Reservation" section.
   
   
3. Complete the online form with your desired business name.
   
   
4. Pay the reservation fee (usually around $50).
   
   
5. Once approved, the name is reserved for 120 days.
   
   

This reservation gives you valuable time to organize your business formation documents while protecting your chosen brand name. Keep in mind, name availability is first-come, first-served—so securing your name early is a smart move.

Pro Tip: Make sure your reserved name follows D.C. naming rules—no misleading terms or prohibited words—and isn’t too similar to existing entities.

6. How to Check a Company’s Good Standing

When you look up a business on the CorpOnline portal, the system displays its current legal status:

• Active – The business is fully compliant with all filing and fee requirements.
  
  
• Revoked – The business has failed to file required reports or pay necessary fees, and its registration has been canceled.
  
  
• Forfeited – The company has violated regulations or missed deadlines, losing its legal privileges.
  
  
• Dissolved – The business has been formally closed, either voluntarily or by administrative action.
  
  

To obtain official confirmation of a company’s compliance, you can request a Certificate of Good Standing through your Access DC account on the portal. This document is commonly used when applying for business loans, licenses, or contracts. A small fee typically applies, and the certificate can be downloaded as a PDF once processed.

Tip: Always check both the business status and its filing history to ensure it’s not just active—but also up to date.

7. Common Mistakes to Avoid

Even though the DC SOS Business Search is user-friendly, many people make simple mistakes that can lead to confusion or missed information. Here’s how to avoid the most common pitfalls:

• Typing the Exact Business Name Incorrectly
  Don’t rely on the full name unless you're absolutely sure of it. Instead, enter part of the name or a keyword. Avoid including suffixes like “LLC,” “Inc.,” or “Corp.” unless they are essential to narrow your search.
  
  
• Confusing Business Registration with Licensing
  A registered entity is not necessarily licensed to operate. Use business.dc.gov to check business licenses—especially for industries like food service, construction, or health care. The CorpOnline tool only confirms registration status.
  
  
• Assuming You Don’t Need an Account
  While basic searches are free and open to the public, features like filing documents, reserving a name, or requesting certificates require logging in with a free Access DC account.
  
  
• Overlooking Similar Business Names
  Many entities may have nearly identical names. Always check the registration number, formation date, and principal address to ensure you’re looking at the correct company—especially important for legal, contractual, or financial dealings.
  
  

8. Who Should Use the DC Business Search Tool?

The DC SOS Business Search isn’t just for business owners—it’s a valuable resource for a wide range of users:

• Entrepreneurs – To check name availability and verify competitors.
  
  
• Attorneys & Accountants – To validate client status and corporate filings.
  
  
• Investors & Financial Institutions – To assess business legitimacy before funding.
  
  
• Government Agencies – For compliance and contract vetting.
  
  
• Consumers – To avoid scams and ensure legitimacy of service providers.
  
  
• Students & Researchers – For academic insights into business trends and registrations.
  
  

Whether you're making legal decisions, planning partnerships, or just doing research, this tool helps you make informed, low-risk choices with confidence.

9. How to Report Business Fraud in Washington DC

If you suspect a business is operating fraudulently—such as using a fake name, working without registration, or misleading customers—you can file a complaint with the DC Department of Licensing and Consumer Protection (DLCP) Enforcement Division.

To report a business, visit dlcp.dc.gov and fill out the official complaint form. You can also contact the DLCP by phone or email for assistance.

Before submitting your complaint, gather the following:

• Business name and any aliases
  
  
• A clear description of the issue
  
  
• Proof or supporting evidence (emails, screenshots, documents, etc.)
  
  
• Entity information from the CorpOnline search, if available
  
  

Providing accurate details—especially verified registration data—will help the DLCP investigate faster and take appropriate enforcement action.

Tip: Always verify business status using the DC CorpOnline portal before engaging in contracts or transactions. It adds a layer of protection and ensures you’re dealing with a legitimate entity.

10. Entity Search vs. Business License Verification: Know the Difference

Business registration and business licensing are not the same—and confusing the two can lead to compliance issues.

• Entity Search (via CorpOnline) tells you if a business is legally registered in Washington, D.C. You’ll see the official name, structure (LLC, Corporation, etc.), formation date, and registered agent.
  
  
• License Verification (via business.dc.gov) confirms whether the business is licensed to operate in a specific industry (e.g., food service, construction, salons).
  
  

Even if a company is registered, it cannot legally operate in regulated fields without an active license. Always use both tools—especially before hiring, investing, or signing a contract.

Tip: Just because a business shows up in the DC SOS search doesn’t mean it’s approved to conduct day-to-day operations. Always check its license status separately.

11. Biennial Report Filing: Staying Compliant in Washington DC

To maintain active status, most businesses registered in Washington, D.C. are required to file a Biennial Report every two years. This report updates the government on your company’s key information, such as business address, registered agent, and member details.

What You Can Do via the CorpOnline Portal:

• Submit your Biennial Report electronically
  
  
• Pay filing fees online
  
  
• Review previous submissions for record-keeping
  
  

Filing Schedule:

• Businesses formed in odd-numbered years must file in odd-numbered years
  
  
• Those formed in even-numbered years file in even-numbered years
  
  

Failure to file by the due date can result in your business being marked as “Revoked” or “Forfeited”, which may lead to penalties, inability to obtain certificates, or even dissolution.

Tip: Mark your calendar ahead of time and use the CorpOnline portal’s reminders to stay in good standing.

12. How to Request Official Business Certificates in Washington DC

If you need official proof of a business’s legal status or filing history in Washington, D.C., the CorpOnline portal makes it easy to request several types of certificates through your Access DC account. Here are the main options:

• Certificate of Good Standing – Confirms the business is active and compliant with all legal requirements.
  
  
• Certified Copies – Official, sealed copies of documents like Articles of Incorporation or Amendments.
  
  
• Certificate of Reinstatement – Issued to businesses that have corrected past compliance issues and regained good standing.
  
  

How to Request:

1. Log in to your Access DC account.
   
   
2. Search for your business entity.
   
   
3. Select the certificate you need from the available options.
   
   
4. Pay any applicable fee (usually minimal).
   
   
5. Download the certificate in PDF format once it’s processed.
   
   

These certificates are commonly required for bank loans, contract bids, licenses, and legal verification—making them essential documents for business owners and professionals alike.
