Hi DVLSTRUONG,
I understand you are curious if your iPhone will change its Device ID when you reset it. I know it's important to have control over your device, so I'm happy to provide some direction to help clarify this.
Check out the footnote in this article, which explains that it will create a new Device ID:
Find your Exchange Device ID in iOS 8 and later - Apple Support
Your device will preserve your Exchange Device ID during iOS updates. If you restore your device to factory settings, it will create a new Exchange Device ID.
This should clarify things for you. Thanks for using the Apple Support Communities, cheers!
