Change your organization's address, technical contact, and more
The admin center is changing. If your experience doesn't match the details presented here, see About the new Microsoft 365 admin center.
You can make changes to your organization profile, such as your organization name, address, phone, and technical contact. You must be a global admin to update this information.
To change the address associated with your bill or subscription, see Change your billing addresses for Microsoft 365 for business.
Edit organization information
You can't change the country or region for your subscription. That's because the country or region where your organization is headquartered determines which services are available to you, the taxes and billing currency, and the location of the data center. To change your organization's country or region, sign up for a new account, choose the desired country or region, and purchase a new subscription.
To change other information on your company's profile page:
In the admin center, go to the Settings > Org settings page.
On the Organization profile tab, select Organization information.
Update your organization's information, then select Save changes.
An explanation of each field is provided below.
What do these fields mean?
||The name entered here is what users will see on the following pages:
Sign-in page: If your users have set up other Microsoft accounts with their business or school email address, they may see the organization name on the sign-in page. This helps them distinguish between their work or school account and their other accounts, so they can identify which one to use when they sign in.
Organization profile link and page: The link to your organization's profile displays the organization name.
Yammer navigation: In Yammer, the left navigation uses the organization name as the name of the home Yammer network.
OneDrive sync client: The organization name is shown in File Explorer on Windows and Finder on Mac, the file paths, the OneDrive activity center, the tooltip of the OneDrive cloud icon, and the OneDrive settings window. Currently, updating the organization name does not update it for configured clients.
MS Teams: Organization Switcher in Teams displays the organization Name
|Address, City, State/Province, Postal code
||The address entered here is what you will see on your bill, under Sold To: The Sold To address on your bill is the same as your organization address on your profile page (see Understand your bill or invoice for Microsoft 365 for business).
|Country or region
||This is the country or region where the company is headquartered. The selected country or region determines which services are available to you, the taxes and billing currency for your country or region, and the location of the data center closest to you (see Microsoft Office license restrictions).
NOTE: Once selected, the country or region cannot be changed. If you want to change the selection, you'll have to cancel your subscription and sign up again. For help with this process, contact support.
||This is the primary number for your company. It's usually the number of your company headquarters.
||This is the email address for the primary technical person who administers your Microsoft 365 subscription. This is the person who will receive communications about Microsoft 365 service status.
||The preferred language determines the language for all communications that are sent from Microsoft to your organization. When you sign up, this setting determines the language used by SharePoint Online, which your users see on your team site. If you change the language preference setting after you sign up, all future communications are sent in the most recent language selected.
NOTE: The language used by SharePoint Online can't be changed.
