Hi Tanvir_Hasan_MS
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
Based on the description, I understand that you would like to check the count of your perpetual licenses that were purchased under an Enterprise Agreement with Microsoft in the Microsoft 365 Admin Center.
Since the perpetual license works differently than an online subscription, given the complexity of the situation, I believe it would be beneficial to escalate this matter to Microsoft Volume Licensing support team for advance troubleshooting. As we are moderator in Community, we are not authorized to check any users' billing details. For this query, it is suggested to directly contact the concerned team by creating a service request in the Microsoft 365 admin center or phone the support hotline, for details, please check Get support - Microsoft 365 admin | Microsoft Learn and Find Microsoft 365 for business support phone numbers by country or region - Microsoft 365 admin | Microsoft Learn.
Your understanding and cooperation are greatly appreciated.
Sincerely,
Roger Shen
