Tata Consultancy Services
Tata Consultancy Services, commonly known as TCS, is a global information technology services, consulting, business solutions, engineering, and digital-transformation company. TCS was established in 1968 as a division of Tata Sons Limited and was later corporatized as a separate company. Following its initial public offering in 2004, Tata Consultancy Services Limited began trading on India’s National Stock Exchange and Bombay Stock Exchange. The company has developed into one of the world’s largest technology-services organizations, serving major enterprises, governments, financial institutions, retailers, manufacturers, healthcare organizations, and other clients across multiple industries.
TCS provides services across artificial intelligence, data and analytics, cloud transformation, consulting, cybersecurity, enterprise applications, engineering, network services, infrastructure management, and business operations. Its current strategy increasingly emphasizes enterprise AI and agentic AI, with TCS building capabilities across infrastructure, data, models, tools, and AI-enabled applications. For the fiscal year ended March 31, 2026, TCS generated approximately US$30.0 billion in consolidated revenue and reported a global workforce of 584,519 at fiscal year-end. The workforce subsequently increased to 598,056 employees as of September 30, 2026.
The HeadquarterLocation page is categorized under New York because TCS has maintained major U.S. operations there since establishing its first New York office in 1979. However, TCS’s global headquarters and registered office are in Mumbai, India, not New York. Its U.S. subsidiary, Tata America International Corporation, currently uses 101 Park Avenue, 26th Floor, New York, NY 10178 as its New York corporate address. Current 2026 federal filings continue to identify that location for Tata America International Corporation.

This is TCS’s current registered corporate office and the address used in the company’s current investor and regulatory communications. It is the correct global headquarters address and should not be replaced by the company’s New York location.

New York should not be described as TCS’s worldwide headquarters. TCS established its first U.S. office in New York in 1979, and the city remains an important North American corporate location, but the company’s global headquarters has remained in Mumbai.

TCS is an enterprise technology-services company.
For a U.S. corporate inquiry, the most direct verified office contact is Tata America International Corporation at 212-557-8038, associated with the company’s New York office at 101 Park Avenue. Business prospects should use the official TCS Request for Services form because it can route an inquiry by geography, industry, technology requirement, and business need. Existing enterprise clients should normally contact their assigned account manager, engagement manager, delivery lead, or commercial representative rather than the general corporate office.
Shareholders should use the dedicated Investor Relations process rather than a general service number. TCS currently publishes Investor.Relations@tcs.com, +91-22-6778-9595, and the MUFG Intime registrar as formal shareholder-service channels. For U.S. media inquiries, use +1-646-617-8221 or andrew.corcione@tcs.com. Having the client account, contract, project, employee, investor folio, or other relevant reference information ready will significantly improve routing.
Complaints involving TCS may concern enterprise contracts, project delivery, billing, recruiting, employment, data protection, vendor relationships, shareholder services, or another corporate matter. Before escalating, collect contracts, invoices, project numbers, correspondence, employee or candidate records, shareholder information, dates, names of representatives, and any prior case references. Because TCS primarily serves enterprises rather than retail consumers, the complaint path should be matched to the exact relationship involved.
For an enterprise-service complaint, begin with your assigned TCS account manager, project manager, engagement lead, or service-delivery contact. Explain the issue in writing where possible and provide the project name, contract reference, affected services, important dates, and the resolution requested. If you do not have a named contact, use TCS’s official Request for Services or corporate contact channel to request routing to the appropriate business team.
Escalate the matter to the department responsible for the issue. Technology-delivery complaints should go to the relevant delivery leadership, recruitment concerns to the recruiting team, investor issues to Investor Relations, and media inquiries to Corporate Communications. Department-specific escalation is usually more effective than repeatedly contacting a general corporate number.
If the first-level team cannot resolve the issue, request review by a senior engagement manager, account executive, delivery director, HR manager, finance manager, or another appropriate supervisor. Include the complete history of the complaint and clearly identify which commitments, contractual terms, invoices, or service outcomes remain disputed.
Submit the complaint in writing through the relevant TCS corporate or stakeholder channel. For shareholder grievances, use Investor.Relations@tcs.com or the official registrar process. Written escalation creates a clear record of the issue, previous responses, requested remedy, and escalation dates.
For a serious unresolved corporate issue, correspondence may be directed to Tata Consultancy Services Limited, 9th Floor, Nirmal Building, Nariman Point, Mumbai 400021, India. U.S. matters can also be directed to Tata America International Corporation, 101 Park Avenue, 26th Floor, New York, NY 10178 when the dispute specifically involves the U.S. subsidiary. Include copies rather than original documents and keep proof of delivery.
Shareholder complaints have a clearly defined escalation process through the registrar, TCS Investor Relations, the company secretary, and external securities-dispute mechanisms. Employment, privacy, contractual, and vendor disputes should use the specialized internal team named in the applicable agreement, employment policy, privacy notice, or commercial contract.
If regulatory escalation is necessary, use the regulator responsible for the particular complaint. TCS shareholders can use SEBI SCORES in India when company and registrar channels do not resolve the grievance. Employment disputes in the United States may involve the EEOC or applicable labor agency, while privacy complaints may involve the appropriate data-protection regulator.
Most TCS relationships are commercial rather than retail consumer relationships, so consumer-protection routes are not always appropriate. Where an issue involves payment, procurement, government contracting, securities, or another regulated relationship, the affected party should use the dispute mechanism relevant to that transaction. Investors can use the current SMART ODR process after exhausting the normal shareholder grievance route.
If contractual and regulatory remedies do not resolve a serious dispute, review the governing contract for mediation, arbitration, jurisdiction, notice, limitation-of-liability, and litigation provisions. Enterprise customers and vendors should obtain qualified legal advice before initiating formal proceedings because TCS contracts can contain detailed dispute-resolution requirements that differ by country, subsidiary, service, and transaction.
