A registration number, sometimes referred to as a Tax Identification Number (TIN), is a number issued by the tax authority in your country/region to identify your organization for tax purposes. We use the registration number to review the details of your account. The review lets us determine if Microsoft can provide you with products and services.
For countries/regions where the registration number is mandatory, the label above the text box indicates what type of number is required. For example, in the following screenshot, the label indicates that a CNPJ (Brazilian) registration number is needed.
For countries/regions where the registration number is optional, you can choose to provide a company legal registration number. Don't enter a personal ID in this field. The following screenshot shows an example of when the registration number is optional.
To find out the format and type of registration number issued by your country/region, contact your tax authority.
When you complete a purchase, you might receive a notification that your account is under review. The review process normally takes about one day to complete but can take longer.
The following screenshot shows the review notification displayed during checkout.
We send an email notification about the review to all global and billing admins on your account. In some cases, the notification is sent to users who have the Billing Account Owner or Billing Account Contributor role on the account. The notification says that a review is currently in process. A confirmation email notification is sent after the review process is complete.
You can check the status of your account in the Microsoft 365 admin center during the review period. To check the status of your review, go to the Billing > Billing accounts page and select the account that you used to complete your purchase.
The following screenshot shows the notification displayed on the billing account details page.
