IQVIA Headquarters & Corporate office

About IQVIA

IQVIA was created in 2016 through the merger of Quintiles Transnational Holdings and IMS Health. Quintiles had built a major global clinical research organization focused on drug development and clinical trials, while IMS Health was known for healthcare information, analytics, pharmaceutical-market data, and technology. Combining the two businesses created a company capable of supporting customers across much of the drug-development and commercialization lifecycle.

Today, IQVIA is a global provider of clinical research services, healthcare intelligence, technology, data analytics, artificial intelligence, commercialization services, real-world evidence, consulting, and healthcare information. Its customers include pharmaceutical companies, biotechnology firms, healthcare providers, payers, governments, researchers, and other organizations across the healthcare ecosystem. IQVIA reports approximately 93,000 employees operating in more than 100 countries.

IQVIA Holdings Inc. remains an independent publicly traded company listed on the New York Stock Exchange under the ticker IQV. Its current corporate headquarters is located at 2400 Ellis Road in Durham, North Carolina. The company’s 2025 sustainability reporting also highlights extensive global data, clinical research, analytics, technology, and healthcare networks that support customers across pharmaceutical development and commercialization.

How to Reach a Real Person at IQVIA

For a general U.S. corporate, sales, or support inquiry, begin with 866-267-4479. Explain whether the matter involves clinical research, laboratory services, technology, commercial analytics, healthcare data, training, sales, or another service. IQVIA is a large global organization, so identifying the exact service or project helps the representative route the request effectively.

Before calling, have the project name, customer organization, study number where applicable, software or service name, contract details, and any existing case number ready. Clinical-trial and laboratory matters may require specific study identifiers that are not handled through ordinary general support.

For certain study-related laboratory inquiries, sites and CRAs can use 800-877-7004. Ethics concerns can be directed to the Business Ethics Office. Career questions should go through IQVIA’s Careers website instead of general customer support.

How to File a Complaint Against IQVIA

Complaints may involve clinical research, data services, technology, contracts, billing, privacy, ethics, laboratory services, employment, or commercial support. Before escalating, gather project identifiers, contracts, invoices, emails, case numbers, system screenshots, and a clear chronology.

Step 1: Contact Customer Service

Start with the IQVIA representative, project team, account manager, or support channel responsible for the service. For general U.S. assistance, use 866-267-4479.

Step 2: Contact the Relevant Department

Clinical-trial, laboratory, software, billing, privacy, sales, and ethics matters are handled by different teams. Request transfer to the department most closely connected with the problem.

Step 3: Request Supervisor or Management Review

If the issue remains unresolved, request review by a project manager, account director, support supervisor, laboratory manager, or other senior representative.

Step 4: Use the Company’s Written Complaint Channel

Provide the complaint in writing through the relevant IQVIA support or business contact channel. Include project information, documents, prior correspondence, and the resolution being requested.

Step 5: Contact Corporate Headquarters

Serious unresolved issues may be sent to IQVIA Holdings Inc., 2400 Ellis Road, Durham, NC 27703. Clearly identify the business unit or project involved.

Step 6: Use the Specialized Complaint or Dispute Department

Business-conduct concerns can be directed to business.ethics@iqvia.com. Privacy, clinical, laboratory, and technology disputes should similarly be directed to the appropriate specialist team.

Step 7: File With the Appropriate Regulator

Depending on the complaint, relevant regulators may include the FDA, Department of Health and Human Services, Office for Human Research Protections, data-protection authorities, securities regulators, or labor agencies.

Step 8: Use Consumer Protection or Financial Dispute Options

IQVIA primarily operates business-to-business and healthcare-research services, so contractual, regulatory, and professional dispute channels are usually more applicable than standard retail consumer mechanisms.

Step 9: Consider Formal Legal or Arbitration Procedures

Significant clinical, contractual, data, privacy, financial, or commercial disputes may require arbitration or litigation. Review the governing agreement carefully and preserve all project and contractual records.
