Executive summary

Microsoft’s corporate headquarters is located on a large campus in Redmond, Washington commonly referenced by the address One (or 1) Microsoft Way, Redmond, WA 98052; this is the address used by Microsoft’s own investor and support pages and appears across business directories [1] [2] [3]. Public information and mapping services consistently place Microsoft’s main campus at that address on a multi‑hundred‑acre site with many buildings [4] [5].

1. What the address means: One Microsoft Way is Microsoft’s headquarters

Company and investor pages list “One Microsoft Way” or “1 Microsoft Way” in Redmond as Microsoft’s corporate address, including the Investor Relations contact and support/community answers, establishing it as the formal headquarters mailing and corporate address [1] [2]. Business directories and data providers also record the same address and ZIP code for Microsoft’s headquarters, reinforcing the address’s status in commercial registries [3].

2. The campus behind the number: scale and location

Microsoft’s global headquarters sits on a sprawling Redmond campus spanning hundreds of acres with more than a hundred buildings and substantial public and green space, a description Microsoft itself provides on its office locations page and echoed by other profiles of the site [4] [5]. Historical and mapping accounts place the campus within the Seattle metropolitan area and describe longstanding campus expansions and infrastructure tied to State Route 520 and local transit access [6] [5].

3. How the address appears across sources — slight variations, same reality

Different sources use slightly different formats — “One Microsoft Way,” “1 Microsoft Way,” or “One Microsoft Way, Redmond, WA 98052‑6399” for investor mail — but these are stylistic variants of the same corporate location rather than contradictory locations [1] [2]. Commercial aggregators and mapping services also index the campus under the same street name and ZIP codes, which is typical for large corporate complexes that use a branded street address [3] [7].

4. Practical details often sought: phone numbers and visitor info

Public support and SEC filings reproduce a corporate phone contact for Microsoft tied to Redmond (425‑882‑8080), which aligns with the company’s corporate campus listing in official documents and help forums [2] [8]. Mapping tools and visitor guides note on‑campus features and transport connections but specific visitor access policies and building numbers vary and are generally governed by Microsoft’s security and visitor procedures, which should be checked directly with Microsoft for current rules [5] [4].

5. Where reporting can be misleading and what is not covered

Some third‑party pages and directories add older or estimated details—like differing counts of buildings or acreage—reflecting updates over time; these are not contradictions about location but differences in snapshot dates and scope [5] [6]. The provided reporting confirms the address and campus identity but does not include Microsoft’s current internal visitor procedures, detailed building‑by‑building maps, or any private mailing codes; those specifics are beyond the available sources and were not asserted here [4] [1].

6. Bottom line and guidance for verification

For practical purposes, “1 Microsoft Way, Redmond, WA 98052” or “One Microsoft Way” is the correct and widely accepted corporate headquarters address for Microsoft across company pages, investor contacts, government filings, and business directories [1] [2] [3]. For phone contact, the Redmond corporate number appears in support and filings (425‑882‑8080), but anyone needing to visit, mail legally sensitive documents, or confirm a specific department should consult Microsoft’s official contact or investor pages for the most current mailing code, building number, or visitor instructions [1] [2] [4].
