About CSC

CSC, legally known as Corporation Service Company, is a privately held global provider of business administration, compliance, legal, tax, digital brand, fund, and corporate services. The company traces its history to 1899 in Delaware, where it began by helping businesses handle incorporation and statutory requirements. Delaware’s growth as a major jurisdiction for U.S. corporate registrations helped CSC develop deep expertise in registered-agent and entity-compliance services, which later became the foundation for a much broader global business.

Today, CSC provides registered-agent services, entity management, business licensing, annual-report compliance, service-of-process management, corporate transactional services, digital brand protection, domain-name management, fraud protection, fund administration, capital-markets services, tax solutions, trust services, and other business-administration products. The company serves organizations ranging from small businesses and law firms to major multinational corporations, private-equity firms, financial institutions, and investment managers. Current CSC information describes more than 8,000 employees, more than 75 locations across 33 countries, service capabilities in more than 140 jurisdictions, and relationships with approximately 90 percent of Fortune 500 companies.

CSC remains privately held and has not been acquired by a public corporation or private-equity owner. The company emphasizes its long-term private ownership structure as an important part of its business strategy. CSC has grown through numerous international acquisitions, including its expansion into fund administration, corporate services, and digital brand management. Its global headquarters remains in Wilmington, Delaware, where CSC opened a modern 148,437-square-foot headquarters facility in 2017. The current headquarters address is 251 Little Falls Drive.

Before contacting CSC, have the client account, company name, entity name, jurisdiction, invoice number, service request, or product involved ready. Because CSC offers a wide range of specialized services, identifying the exact product helps the company route the inquiry much more efficiently.

How to File a Complaint Against CSC

Complaints may involve registered-agent service, filings, invoices, entity data, service of process, business licensing, fund administration, domain services, or customer support. Before escalating, gather the client account, relevant entity, jurisdiction, filing receipts, invoices, service records, and previous correspondence.

Step 1: Contact Customer Service

Use CSC’s current Customer Service process or call 866-403-5272. Explain the complaint and identify the product, entity, or transaction involved.

Step 2: Contact the Relevant Department

Registered-agent, entity, licensing, tax, fund, domain, service-of-process, and billing concerns should be routed to the specialized team responsible for that service.

Step 3: Request Supervisor or Management Review

If the assigned specialist cannot resolve the issue, request escalation to the appropriate account manager, service manager, or departmental leadership team.

Step 4: Use the Company’s Written Complaint Channel

Submit the issue through CSC’s official service-request process or send written correspondence to the applicable CSC specialist. Preserve emails, invoices, filing confirmations, and case references.

Step 5: Contact Corporate Headquarters

Serious unresolved company-level matters can be directed to Corporation Service Company, 251 Little Falls Drive, Wilmington, DE 19808.

Step 6: Use the Specialized Complaint or Dispute Department

Legal, registered-agent, privacy, compliance, fund, security, and service-of-process disputes may require specialized internal review rather than general Customer Service.

Step 7: File With the Appropriate Regulator

The appropriate regulator depends heavily on the service. Trust, fund, corporate, privacy, tax, or financial-services issues can involve different state, federal, or international authorities.

Step 8: Use Consumer Protection or Commercial Dispute Options

CSC primarily serves businesses and professional clients, so most disputes are commercial matters governed by service agreements rather than ordinary retail consumer rules.

Step 9: Consider Formal Legal or Arbitration Procedures

For substantial filing, legal-service, transaction, fund, contractual, or financial disputes, review the applicable CSC agreement for notice, liability, governing-law, and dispute provisions. Qualified commercial legal advice may be appropriate for significant unresolved matters.
