How to Correct an Incorrect Company Name in Microsoft 365

Log in to the Microsoft 365 admin center using your global tenant administrator credentials.

On the left navigation menu, expand the 'Settings' section and select 'Org settings'.

Click on the 'Organization profile' tab, select 'Organization information', type in the corrected company name, and click 'Save'.

Inside the Microsoft 365 admin center, click on the 'Help & Support' icon located at the bottom right corner of the screen.

Type 'Contact Support' into the search bar and select the option to speak with an agent.

Choose the phone support option, explain which organization name was entered incorrectly during registration, and provide the correct business name.

Visit the official Microsoft website and navigate to the global customer service phone numbers list to find the contact number for your specific region.

Call the support line and explain to the frontline team that you are a tenant administrator who needs to correct an incorrect company name on a business subscription.

If the phone number tied to your Microsoft admin account is also incorrect, ensure you explicitly provide your current phone number and contact details to the support agent so they can follow up.
