    Hi Payton Calabro,

    I understand how difficult it can be to locate the details of an older Office purchase.

    If Word 2016 was previously activated, the license may already be associated with the Microsoft account you used at that time. Please check https://account.microsoft.com/services using any Microsoft account that may have been used for the purchase or activation.

    If Word 2016 does not appear there, check the original purchase confirmation:

    • For a Microsoft Store purchase, review your Microsoft order history.
    • For a retailer purchase, check the confirmation email, receipt, packaging, or product-key card.

    Could you let me know where Word 2016 was purchased and whether it is still installed on an older computer? Please do not share the actual product key or email address in your reply. Thank you so much for your understanding.

    Sign in to Microsoft account → Services & subscriptions with the account used to purchase Word 2016, then install and activate Word from that account instead of trying to recover or re-enter the product key.

    If Word 2016 was already redeemed

    1. Open Services & subscriptions.
    2. Sign in with the Microsoft account used when Word 2016 was purchased or downloaded.
    3. Locate Word 2016, Office 2016, or the corresponding one-time purchase.
    4. Select Install.
    5. After installation, open Word and sign in with that same Microsoft account if activation is requested.

    Once a key has been redeemed, the product is associated with the Microsoft account. Microsoft does not display the complete key in Word or normally show it online; the account replaces the key for installation and activation.^1^

    If entering the original key produces “This product key has already been used,” do not enter it again. That message means the key was previously redeemed; install and activate through Services & subscriptions instead.[^2^](https://support.microsoft.com/microsoft-365-activation-licensing/this-product-key-has-already-been-used-error-in-office ""This product key has already been used" error in Office | Microsoft Support")

    To identify the associated account on a computer where Word still works:

    1. Open Word and a document.
    2. Select File → Account.
    3. Under the product name, note the email address shown after Belongs to.
    4. Use that account on the Services & subscriptions page.^1^

    If the purchase is not listed

    • Purchased from Microsoft Store but never installed: Sign in to Microsoft Store with the purchasing account, open Order History, locate the Word or Office one-time purchase, and select Install Microsoft 365 to display the key and continue setup.^1^
    • Purchased from another retailer: Check the purchase email, receipt, order history, packaging, or product-key card. A key has the format XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. If it is missing or rejected, contact the seller; Microsoft’s guidance recommends contacting the seller for a nonworking separately purchased key.^3^
    • Purchased through an employer’s Workplace Discount Program/Home Use Program: This is an exception—the key may be available on the program’s Order Details page and is required for certain Office Professional Plus 2016 installations.^1^
    • No account or purchase record can be found: Contact Microsoft Support with the receipt or other proof of purchase.^3^
