Hello WANG Zihjie,
There is no public-facing system that allows external users to verify Microsoft employees by badge number. Internal badge IDs such as “v-jingmiwang” are used only within Microsoft’s corporate directory and cannot be validated outside of official Microsoft channels. If you have received a notice or communication and want to confirm its authenticity, the correct approach is to check whether the message came from an official Microsoft domain (for example, @microsoft.com) and whether the communication aligns with information published on Microsoft’s official websites.
If the message is related to licensing, billing, or account security, you should log in directly to the Microsoft 365 Admin Center or your personal Microsoft Account portal and verify if the same information is reflected there. Do not rely on badge numbers or internal identifiers, as they are not intended for external validation. If you remain uncertain, the safest step is to contact Microsoft Support directly through the official support site and provide them with the details of the notice you received. They can confirm whether the communication is legitimate.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
Domic Vo.
