If you are an Android user and you use Internet on your device, your device is automatically assigned with a unique random number called Google advertising ID. The Google advertising ID anonymously collects your information which is further used to display advertisements and other information on your device depending upon your areas of interest. Although it is not required to reset the Google advertising ID, You Can do so to generate a new Google Advertising ID in order to get a fresh start with the interest-based ads that Google displays. In addition to this, if you want, you can opt out of the interest-based ads altogether by unchecking the ‘Opt out of interest-based ads’ checkbox. When opt out of the interest-based ads, Google ignores your advertising ID, and displays random ads on your device’s screen. Once you have understood the use and importance of the Google advertising ID, here is how you can reset it to get a new one: Step 1: Open Google Settings on your Android device by tapping on menu and then on Google Settings once all apps are displayed on the screen. Step 2: Locate and tap on the Ads menu under Services. Step 3: Tap on “reset advertising ID” on the new page. The page lists the current advertising ID on the same page. Step 4: Confirm the reset when the confirmation prompt is displayed. Once you reset the advertising ID, a new ID is displayed immediately on the same page. Since a new ID is assigned now, advertisers cannot link past actions anymore to the device if only the advertising ID was used for that. Once done, your new Google advertising ID would appear at the bottom of the interface.
