1 Microsoft WayRedmond

1. A corporate address that represents a vast campusnot a single office

The name “One Microsoft Way” is best understood as an anchor for an entire corporate campus rather than a solitary headquarters tower: Microsoft itself describes its global headquarters as occupying 500 acres with public spaces and more than 125 buildingslanguage that frames the address as the gateway to a sprawling site ^[1]. Independent directories and mapping services likewise treat the location as the central Redmond campus — listing 1 Microsoft Way or One Microsoft Way as the company’s main office and mapping hub for multiple buildings across the property ^{[3] [5]}.

2. Multiple official variants and delivery details in public records

Public-facing Microsoft pages and filings use the One Microsoft Way address with different delivery codes and ZIP+4 endings depending on context: investor relations lists One Microsoft WayRedmondWashington 98052-6399 ^[4]a community Q&A and support pages show One Microsoft WayRedmondWA 98052 as contact information with phone numbers ^[2]and business directories give a ZIP+4 that ends in 8300 ^[3]. These discrepancies reflect standard corporate practice of assigning different mail routing codesbuilding identifiers or department-specific ZIPs on a large campus rather than indicating conflicting facts about location.

3. Contact points and official phone numbers tied to the address

Corporate contact data tied to One Microsoft Way appears in official filings and support pages: Microsoft’s SEC filing and Microsoft Support references list a Redmond phone number 882-8080alongside the corporate address ^{[6] [2]}. This consistency in telephone contact supports the use of One Microsoft Way as a consolidated corporate contact hub even as mail or internal building addresses vary across documents.

4. Historical and contextual markers for the Redmond headquarters

Multiple sources note the long-standing role of the Redmond campus as Microsoft’s headquarters and global hubincluding histories documenting the company’s move to the site in the 1980s and descriptions of the campus footprint and facilities ^{[7] [5]}. Company-owned pages and independent dossiers reiterate the campus’s role as the central location for Microsoft’s strategic management and many operational functions ^{[8] [9]}. Those accounts underline that “1 Microsoft Way” functions as both a brandable corporate address and an operational locus for tens of thousands of employees.

5. What reporting does not resolve and where caution is warranted

Available sources do not provide a singlecanonical postal suffix or a definitive map tying every building number on the campus to “1 Microsoft Way,” nor do they resolve which exact building should be visited for a particular department; insteaddifferent departments and documents use different ZIP+4 endings or building identifiers ^{[10] [4] [3]}. Reporting cannot confirm on its own whether a specific visitor centeroffice suite or public entrance corresponds to a particular ZIP+4 without directdepartment-level guidance from Microsoft; thereforefor deliveries or visits the company’s official channels should be consulted ^{[2] [4]}.

6. Interpretation: address as a legallogistical and symbolic center

Taken togetherthe sources present One Microsoft Way as a legal headquarters address used in filings and investor relationsa logistical hub for phones and mail routed across a large campusand a symbolic brand identifier for Microsoft’s Redmond presence ^{[6] [4] [1]}. Alternative readings focus on the practical reality that large corporations commonly distribute operations and mailing codes across many buildingswhich explains the multiple address variants found in support pagesdirectories and filings ^{[3] [10]}.
