How to Search Washington DC Business Records

Washington DC's business entity records are maintained by the Department of Consumer and Regulatory Affairs (DCRA), specifically the Corporations Division. Every LLC, corporation, limited partnership, and nonprofit that formally registers in the District of Columbia receives a public record in the city's business database.

Washington DC has a unique business environment as the nation's capital. The District is home to a massive concentration of government contractors, lobbying firms, trade associations, nonprofits, law firms, and consulting companies — all driven by proximity to the federal government. Despite its relatively small geographic size, DC hosts a substantial number of registered business entities.

The DCRA Corporations Division is responsible for:

• Registering new business entities (LLCs, corporations, partnerships, nonprofits)
• Maintaining the business entity database with current information on all registered entities
• Processing biennial reports
• Recording amendments, mergers, dissolutions, and name changes
• Providing public access to business entity records through the CorpOnline portal

Key facts about DC business records:

• Online portal: DC's official business entity search is accessible through the CorpOnline system at corponline.dcra.dc.gov. The system provides entity search and filing capabilities.
• File Number format: DC assigns each entity a unique file number. This is the most reliable way to find a specific entity.
• Biennial reports: DC requires most entities to file biennial reports (every two years).
• High concentration of nonprofits and associations: Because DC is the seat of government, a disproportionate number of registered entities are nonprofits, trade associations, and 501(c)(4) organizations.
• Government contractor hub: Thousands of government contracting firms are registered in DC or maintain foreign entity registrations here.
• Filed API coverage: The Filed API currently indexes approximately 494,000 DC business entities, sourced via the District's ArcGIS API — making DC one of the most recently added and comprehensively covered jurisdictions in the Filed system.

Whether you are verifying a DC business, conducting due diligence on a K Street consulting firm, or building an application that needs DC entity data, this guide covers the full process.

DCRA CorpOnline is the official public-facing database maintained by the DC Department of Consumer and Regulatory Affairs, Corporations Division. It provides access to business entity records filed with the District of Columbia.

What you can find in CorpOnline:

• Entity Name — The legal name as registered with DC (e.g., "Capitol Strategy Partners LLC")
• File Number — DC's unique entity identifier
• Entity Type — The legal structure: Limited Liability Company, Corporation, Nonprofit Corporation, etc.
• Status — Active, Revoked, Dissolved, Inactive, etc.
• Date of Formation/Registration — When the entity was first filed with DC
• Home Jurisdiction — For foreign entities, the state or country of original formation
• Registered Agent — The person or company designated to receive legal documents, along with their DC address
• Principal Office Address — The entity's primary business address
• Governors/Officers — Names of people who manage the entity

CorpOnline is functional for individual lookups but, like most government portals, is not designed for programmatic access or bulk data retrieval.

Accessing CorpOnline:

The DCRA CorpOnline system is available at corponline.dcra.dc.gov. The search interface allows lookups by entity name and file number. It is free to use.

Here is a detailed walkthrough of how to search for a business entity using DC's official search tool:

Step 1: Navigate to the CorpOnline portal

Go to corponline.dcra.dc.gov. This is the main search interface for DC business entity records.

Step 2: Choose your search method

DC offers several search options:

• Entity Name Search: The most common method. Enter the full or partial business name.
• File Number Search: If you have the entity's file number, enter it for an exact match. This is the fastest and most reliable method.

Step 3: Review the results list

The search returns a list of matching entities showing the entity name, file number, type, and status. Click on an entity to view its full record.

Step 4: Review the entity detail page

The detail page contains the public record for the entity:

• Filing Information: Entity type, file number, formation date, and status
• Registered Agent: Name and address of the designated agent for service of process
• Principal Office: The entity's primary business address
• Governors/Officers: Names of people managing the entity
• Biennial Report Status: Whether the entity is current on filings

Tips for effective DC business searches:

• Use the file number whenever possible. With hundreds of thousands of entities, name searches can return many results — especially for common terms like "Consulting" or "Group."
• Drop entity suffixes for broader results. Search for "Capitol Strategy" instead of "Capitol Strategy Partners LLC."
• Many DC entities are nonprofits. If you are searching for a trade association or advocacy group, check the nonprofit entity types as well.
• Foreign entity registrations are common. Many businesses operating in DC are incorporated in Delaware, Virginia, or Maryland and registered as foreign entities in DC. This is standard practice.
• Check the registered agent carefully. Many DC entities use commercial registered agent services with DC addresses, even if the business primarily operates in Virginia or Maryland suburbs.

DC uses specific designations for different entity types in its business registry. Understanding these labels helps you interpret search results correctly.

Domestic entities (formed in DC):

• Domestic Limited Liability Company — An LLC formed in DC. Common for consulting firms, lobbying shops, and small businesses operating in the District.
• Domestic Stock Corporation — A for-profit corporation formed in DC.
• Domestic Nonprofit Corporation — A nonprofit formed in DC. DC has an exceptionally high number of nonprofits due to the concentration of trade associations, advocacy groups, and charitable organizations in the capital.
• Domestic Limited Partnership — An LP formed in DC.
• Domestic Limited Liability Partnership — An LLP formed in DC, commonly used by DC-based law firms and accounting practices.
• Domestic Professional Corporation — For licensed professionals operating in DC.

Foreign entities (formed outside DC, registered to do business here):

• Foreign Limited Liability Company — An LLC formed in another state or country, authorized to operate in DC.
• Foreign Stock Corporation — A corporation formed elsewhere (commonly Delaware, Virginia, or Maryland), registered in DC.
• Foreign Nonprofit Corporation — A nonprofit formed elsewhere, registered in DC.
• Foreign Limited Partnership — An LP formed elsewhere, registered in DC.
• Foreign Limited Liability Partnership — An LLP formed elsewhere, registered in DC.

Entity type distribution in DC:

Domestic and Foreign Nonprofit Corporations make up a larger share of DC's registry than in most states, reflecting the District's unique role as the hub for national associations, advocacy organizations, and think tanks. Domestic LLCs and Foreign Stock Corporations are also prominent, driven by consulting firms, government contractors, and companies with DC operations incorporated elsewhere.

Washington DC requires most registered business entities to file biennial reports (every two years) to maintain their active status.

Key facts about DC biennial reports:

• Filing period: Reports are due every two years, based on the entity's registration anniversary.
• Filing fee: Varies by entity type. LLCs pay approximately $300 for their biennial report — significantly higher than most states.
• Online filing: Reports can be filed online through the CorpOnline system.
• Consequence of non-filing: Entities that fail to file their biennial report are placed in "Revoked" status. Continued non-filing can lead to administrative dissolution.

What the biennial report updates:

• DC biennial reports confirm or update the following:
• Entity name
• Registered agent name and address
• Principal office address
• Governor/officer names and addresses

Why biennial matters for research:

Like other biennial-reporting jurisdictions, DC entity data may be updated less frequently than in states with annual reports. A filing that is up to two years old is considered current. When verifying a DC entity, check the status field rather than the last filing date.

"Revoked" status in DC:

A common status you will encounter in DC records is "Revoked." This means the entity has failed to file its biennial report or pay required fees. A revoked entity has not been dissolved — it can be reinstated by filing the overdue reports and paying back fees. However, a revoked entity may not be in good standing and may have limitations on its ability to conduct business.

Biennial report data via the Filed API:

curl "https://filed.dev/api/v1/entity/dc-0001234" \
  -H "Authorization: Bearer your_api_key"

{
  "id": "dc-0001234",
  "name": "CAPITOL STRATEGY PARTNERS LLC",
  "state": "DC",
  "type": "Domestic Limited Liability Company",
  "status": "Active",
  "filing_date": "2018-09-05",
  "filing_number": "0001234",
  "registered_agent": {
    "name": "CSC - Lawyers Incorporating Service",
    "address": "1090 Vermont Ave NW, Suite 430, Washington, DC 20005"

If you need Washington DC business data programmatically — for application integrations, bulk verification, compliance workflows, or CRM enrichment — the Filed API provides a direct alternative to the DCRA CorpOnline portal.

The Filed API currently indexes approximately 494,000 DC business entities, sourced via the District's ArcGIS API. DC is one of the most recently added jurisdictions, providing comprehensive coverage of the District's business registry. You can search by name, retrieve entity details, and get structured JSON consistent with every other state in the API.

Example: Search DC businesses by name

curl "https://filed.dev/api/v1/search?q=Capitol+Strategy+Partners&state=DC" \
  -H "Authorization: Bearer your_api_key"

Response:

{
  "results": [
    {
      "id": "dc-0001234",
      "name": "CAPITOL STRATEGY PARTNERS LLC",
      "state": "DC",
      "type": "Domestic Limited Liability Company",
      "status": "Active",
      "filing_date": "2018-09-05",
      "filing_number": "0001234",

        "address": "1090 Vermont Ave NW, Suite 430, Washington, DC 20005"
      }
    }
  ]
}

Example: Look up a specific DC entity by file number

curl "https://filed.dev/api/v1/entity/dc-0001234" \
  -H "Authorization: Bearer your_api_key"

Example: Cross-state search for a company in DC, Virginia, and Maryland

# Many DC-area companies are registered in multiple jurisdictions
curl "https://filed.dev/api/v1/search?q=Beltway+Consulting&state=DC,VA,MD" \
  -H "Authorization: Bearer your_api_key"

Why use the API instead of CorpOnline:

• Structured JSON output. CorpOnline returns HTML pages. The API returns clean JSON you can parse and store.
• 494,000 entities indexed. Comprehensive coverage of DC's business registry via the ArcGIS data source.
• Normalized across states. DC entity types are returned in the same schema as every other state.
• Bulk lookups. Verify thousands of DC entities without manual searches.
• Cross-state search. Search DC, Virginia, and Maryland simultaneously — essential for the DC metro area where businesses frequently operate across jurisdictional lines.
• Same API for every state. One integration covers DC and all other supported states.

Use the DCRA CorpOnline portal when:

• You need to look up a single DC business as a one-off task.
• You need to file documents with DCRA (biennial reports, amendments, new registrations).
• You need official certificates of good standing or certified copies.
• You need to access specific filing documents.

Use the Filed API when:

• You are building an application that requires DC business verification.
• You need to search DC entities alongside other states in a single workflow.
• You process more than a few DC lookups per week and need structured data.
• You want to integrate DC business data into your CRM, ERP, compliance system, or onboarding flow.
• You need consistent data formatting without scraping HTML.

Feature comparison:

For developers and businesses that need DC entity data at scale, the API is the practical choice. For occasional research or filing paperwork, CorpOnline works fine.

Here are real-world scenarios where you would search DC business records:

Scenario 1: Verifying a K Street consulting or lobbying firm

You are conducting due diligence on a consulting firm or lobbying shop based in DC.

1. Search CorpOnline (or the API) by the company name.
2. Confirm the entity exists and its status is "Active" (not "Revoked").
3. Check the formation date — does it align with the firm's claimed history?
4. Verify the registered agent is current.
5. Review governors/officers listed in the record.

Scenario 2: Service of process on a DC LLC

You need to serve legal papers on a DC LLC.

1. Search for the entity by name or file number.
2. Find the registered agent name and address.
3. Serve the registered agent at the listed address.
4. If the registered agent has resigned, DC law allows service on the Mayor or designated official as a fallback.

Scenario 3: Researching a trade association or nonprofit in DC

You want to verify a national trade association headquartered in DC.

1. Search by the organization name. Many associations are registered as Domestic or Foreign Nonprofit Corporations.
2. Verify "Active" status — many associations that have moved or merged may still have DC registrations in "Revoked" status.
3. Check the registered agent — large associations typically use commercial agent services.

Scenario 4: Cross-jurisdictional DC metro area search

A company claims to be "based in Washington, DC" but might actually be registered in Virginia or Maryland.

# Search across DC, Virginia, and Maryland
curl "https://filed.dev/api/v1/search?q=Beltway+Solutions&state=DC,VA,MD" \
  -H "Authorization: Bearer your_api_key"

This is common in the DC metro area — many businesses have their physical offices in Arlington (VA) or Bethesda (MD) but reference "Washington, DC" in their marketing.

Scenario 5: Bulk verification of DC businesses

Your compliance team needs to verify hundreds of DC-based entities, particularly government contractors.

# Verify multiple DC businesses programmatically
for company in "BOOZ ALLEN HAMILTON" "K STREET ADVISORS" "NATIONAL ASSOCIATION OF"; do
  curl -s "https://filed.dev/api/v1/search?q=$(echo $company | tr ' ' '+')&state=DC" \
    -H "Authorization: Bearer your_api_key" | jq '.results[0] | {name, status, filing_number}'
done
