The Advertising ID is a randomly generated number that identifies the LG smartphone and is used to assign interests and usage patterns (but not personal information such as name, etc.) to display personalized advertising.

On the LG smartphone, or on Android, it is possible to reset the ad ID, which creates a new profile.
