Office 365 Graph API "businessPhones" organization property

New Contributor

There is a property called "businessPhones" in the Graph API that will pull the phone number for your organization:


Where is this field located in AAD if I wanted to update this phone number in the GUI?

I cannot find this field anywhere in AAD, but would like to know where the "businessPhones" property is being pulled from. Right now the API isn't pulling any info.

In the UI, you can configure it by opening the Organization Card (click the Org name on top of the M365 admin center) or this link directly:
So I followed your instructions, but when I run the Graph API, the "businessPhones" section is still blank:
"businessPhones": []

Hello, @JohnnyRani, the Azure AD Graph (v1.6) property for this is telephoneNumber. Check this table with User property differences between Azure AD Graph and Microsoft Graph for more deteails.


This thread can be also useful in your case.


Also, I recommend to get clued up about Microsoft 365 backups to get nearly-instant recovery in the moment of system errors or deleted by accident files.
