IBM Headquarters & Office Locations: Full 2026 Directory

IBM's global headquarters is at 1 New Orchard Road, Armonk, New York — a 25-acre campus in Westchester County that has served as the company's corporate nerve center since 1964. Beyond Armonk, IBM maintains a sprawling footprint across more than 175 countries, with major regional hubs in New York City, Austin, Bangalore, London, and Tokyo anchoring its global operations. Whether you're doing due diligence on a prospect, mapping the enterprise tech landscape, or just need the right mailing address, this directory covers every significant IBM office location for 2026.

Where is IBM headquartered?

IBM's world headquarters is located at 1 New Orchard Road, Armonk, New York 10504. The campus sits in the town of North Castle in Westchester County, roughly 40 miles north of Midtown Manhattan. IBM relocated its corporate offices here from 590 Madison Avenue in New York City in 1964, consolidating executive leadership and corporate administration onto a single campus.

The Armonk campus is a low-profile, woodland property — deliberately understated by the standards of major tech companies. It houses IBM's C-suite, board operations, investor relations, legal, and global strategy functions. It is not a customer-facing site; most IBM client engagements happen through regional offices, and particularly through the Manhattan and Austin hubs.

IBM's full legal name is International Business Machines Corporation. Its NYSE ticker is IBM, and its registered state of incorporation is New York. The Armonk address is the one that appears on SEC filings, annual reports, and official corporate correspondence.

What are IBM's main US office locations?

Beyond Armonk, IBM has a significant domestic footprint with several offices that carry more day-to-day commercial weight than the headquarters itself.

New York City — 590 Madison Avenue

IBM's Manhattan office at 590 Madison Avenue (also known as the IBM Building) is the company's most prominent client-facing location in the United States. It sits in Midtown Manhattan and has been associated with IBM since the building's construction in 1983. This office houses sales, consulting, and marketing teams that serve the dense concentration of financial services, media, and enterprise clients in the New York metro area.

Austin, Texas

IBM's Austin campus is one of its largest US technical hubs. Located in the north Austin tech corridor, it houses significant engineering, cloud infrastructure, and research teams. Austin has grown in strategic importance as IBM has expanded its hybrid cloud and AI business lines — many of the teams working on IBM Cloud and Watson AI products are based here or distributed between Austin and the Research Triangle in North Carolina.

Research Triangle Park, North Carolina

IBM has maintained a major presence in RTP since the 1970s. The campus houses IBM Research and significant software development teams. It remains one of IBM's largest US campuses by headcount.

Where are IBM's international offices?

IBM's international operations are among the most extensive of any technology company. IBM's annual report consistently shows that more than 50% of the company's revenue originates outside the United States, which is reflected in the scale of its international office network.

What is IBM Research and where are its labs?

IBM Research is one of the world's largest corporate research organizations, with a history stretching back to 1945. It operates across multiple dedicated research facilities globally, separate from IBM's commercial offices.

"IBM Research has defined the frontiers of information technology for more than 75 years. Our work led to the foundation of much of what we know as modern computing — from relational databases to RISC architecture to quantum computing."

— IBM Research official overview, IBM.com

IBM Research labs are located in:

• Yorktown Heights, NY — Thomas J. Watson Research Center (global HQ of IBM Research)
• Cambridge, MA — MIT-IBM Watson AI Lab (joint initiative)
• San Jose, CA — Almaden Research Center
• Zürich, Switzerland — IBM Research Europe
• Haifa, Israel — IBM Research Israel
• New Delhi, India — IBM Research India
• São Paulo, Brazil — IBM Research Brazil
• Melbourne, Australia — IBM Research Australia
• Tokyo, Japan — IBM Research Tokyo

These research facilities are relevant to enterprise sales teams because they often serve as early indicators of IBM's product roadmap priorities — quantum computing, AI, and hybrid cloud investments frequently surface at the research level before appearing in IBM's commercial product line.

How many employees does IBM have and where are they?

As of its most recent annual filing, IBM's 10-K with the SEC reports approximately 288,000 employees globally. This figure reflects a significant restructuring that began with IBM's 2021 spin-off of its managed infrastructure services division into a separate company called Kyndryl — which reduced IBM's headcount from roughly 350,000 pre-spin to the current level.

India is IBM's largest single-country employee base outside the United States, with estimates consistently placing IBM India's headcount above 100,000 across its various delivery and development centers. The US remains the headquarters country with the next-largest concentration, followed by the UK, Brazil, and Japan.

IBM operates under a hybrid work model. Physical office attendance varies by role — consulting and client-facing teams tend to be more office-present, while software engineering and research roles are more distributed. This means raw office location data understates the geographic spread of IBM's actual workforce.

Why do sales teams research IBM office locations?

Understanding where IBM operates matters for two distinct sales use cases: selling to IBM, and selling to companies that are already IBM customers or that compete with IBM's product lines.

If you're selling to IBM, office location data tells you where regional procurement decisions happen — which is rarely Armonk. Major technology purchasing decisions at IBM are often made by business unit leaders in Austin, New York, or London, not at the corporate headquarters. Mapping IBM's office locations to the business units and product lines housed there helps you route outreach to the right geography.

If you're selling to IBM's customers — for example, if you offer an alternative to IBM Cloud, IBM Security, or IBM's AI products — then IBM's customer base is your target list. The most direct way to build that list is to identify companies that are actively using IBM products, either through job postings that reference IBM tools, tech stack signals, or procurement data. Tools like Stealery let you search by competitor name and surface companies using IBM products, filtered by size and geography, which is considerably faster than manual research across LinkedIn or job boards.

Either way, IBM's office location directory is the starting point for understanding where buying authority lives within the company and where IBM's customer concentration is heaviest by region.

Has IBM moved or changed its headquarters recently?

IBM has not relocated its global headquarters. The Armonk, New York address has been IBM's official corporate headquarters since 1964, and there are no announced plans to change this. However, IBM has made significant structural changes to its real estate footprint in recent years.

Following the Kyndryl spin-off in November 2021 and ongoing hybrid work adoption, IBM has consolidated some of its regional office presence. Several smaller satellite offices were closed or reduced between 2020 and 2023 as IBM shifted to a hub-and-spoke model — maintaining large campuses in strategic cities while reducing its presence in smaller markets. The net result is that IBM's active office count is meaningfully smaller than it was five years ago, even as its geographic reach (175+ countries) remains unchanged.

IBM has also invested in its client briefing center network. These are dedicated client-facing facilities in cities like New York, London, Tokyo, and Singapore — purpose-built for executive engagements rather than day-to-day operations. If you're trying to reach IBM's commercial teams, these locations (and the regional sales offices attached to them) are more relevant than the Armonk headquarters.
