- Product
- Microsoft Office for Mac
- Device & OS
- macOS
- Scenario
- Activating a volume-licensed Microsoft Office installation provided by a school, university, or company.
- Observed behavior
- Individual retail product keys are not applicable for volume licensing; activation requires a specific Microsoft Volume License Serializer instead.
Ensure you have your organization or school's IT support contact information ready, as volume licenses are managed exclusively by the issuing institution.
Obtain and Run the Microsoft Volume License Serializer
Activate your volume-licensed Office for Mac using the specific Volume License Serializer provided by your institution.
Office for Mac volume licenses do not use standard 25-character retail product keys. Instead, they require a specialized tool called the Volume License Serializer, which validates the installation against your organization's licensing agreement.
Reach out to your school or company's IT support to request the Volume License Serializer package for your specific version of Microsoft Office.
Save the provided .pkg Serializer file to your Mac's local drive, such as the Downloads or Desktop folder.
Double-click the Volume License Serializer package and follow the on-screen prompts to complete the installation process.
Install Microsoft Office for Mac if you haven't already. Open an application like Word, click on the 'Word' menu in the top bar, and select 'About Microsoft Word' to confirm the volume license is successfully activated.

Switch to WPS Office for Mac
If you are having trouble activating your school or company's Microsoft Office volume license, consider using WPS Office. It is a free, lightweight, and powerful alternative that allows you to create, edit, and share documents effortlessly on your Mac without complex licensing tools.
- 1. Download WPS Office: Visit the official WPS Office website and click the free download button for macOS.
- 2. Install the application: Open the downloaded installer file and drag the WPS Office icon to your Applications folder.
- 3. Open your files: Launch WPS Office and directly open your existing Microsoft Office files without worrying about formatting issues.

Frequently Asked Questions
Why can't I use a standard 25-character product key for my Mac volume license?
Volume licenses for Mac use a completely different activation method managed by a Volume License Serializer tool. Retail 25-character keys are only designed for individual consumer purchases.
Where do I download the Microsoft Volume License Serializer?
The serializer must be downloaded from the Microsoft Volume Licensing Service Center (VLSC) or Microsoft 365 Admin Center by your organization's IT administrator. End-users typically receive the installation file directly from their IT department.
Does the Volume License Serializer need to be run before or after installing Office?
It is generally recommended to run the Volume License Serializer first, followed by the Office installation package, but running it after installing Office also works to successfully activate the suite.
What should I do if the serializer fails to activate my Office for Mac?
Ensure you are using the correct serializer version for your Office installation. If you install Office 2021 but run a 2019 Serializer, the activation will fail. If the version mismatch persists, contact your IT admin to obtain the correct file.
