Advertising IDs are used by companies to send you targeted ads based on your activity. Each iPhone has its own unique advertising ID—at least, they used to. Can you still reset the ID on your iPhone or iPad?

The idea behind an advertising ID is similar to the one behind browser cookies. Companies use things like your location, shopping habits, and app usage to show you ads that you’re more likely to interact with. If you care about privacy, it’s something to think about.

There’s good news for iPhone users, though. Starting in iOS 14, apps are forced to ask before they can track your activity. You no longer have to worry about “resetting” your advertising ID. In fact, you can even stop all apps from requesting to track you.

What you can still do is turn off personalized ads. This will limit the number of targeted ads that you see, but not the number of total ads.

First, open the “Settings” app from your iPhone or iPad home screen.

Open the "Settings" app.

Select “Privacy” from the Settings.

Select "Privacy" from the menu.

Tap “Apple Advertising” at the bottom.

Now tap "Apple Advertising" at the bottom.

Simply toggle off the switch for “Personalized Ads.”

Simply toggle off the switch for "Personalized Ads."

That’s all there is to it! Apple has done a lot to limit how apps can track you, which makes things like advertising IDs less scary on iPhones.
