How to Reset Google Ad ID

Open Settings on the phone. Tap Google. Find Ads. The reset sits in there.

Thirty seconds of work, start to finish. A fresh random number replaces the old one.

Then comes the part nobody covers. That number was carrying far less than its name suggests. Reset it and most of what shapes your ads carries on exactly as before.

Only the Advertising ID Can Be Reset

Your Google Ads account number is not the thing you are looking for. Ten digits, printed with dashes at the top corner of the account. That one is permanent. Want a different account number, open a different account.

Conversion tag IDs are not it either. You replace those by creating a new conversion action. Nothing resets.

The advertising ID is the resettable one. It lives on the device rather than inside any account. Apps receive it from Google Play services. They use it to recognize the same phone across separate sessions.

Three separate numbers, one shared nickname. Which is why plenty of people searching for this land on a page about their advertising account instead of their handset.

Where the Advertising ID Reset Actually Hides

Settings, then Google, then Ads on most Android builds. Manufacturers move it around. Samsung buries it somewhere slightly different than a Pixel does, and the wording drifts between versions.

Faster route. Open Settings and search the word ads. The screen surfaces regardless of where anybody put it.

Two options usually sit there. Reset hands you a new random identifier. Delete removes it altogether.

Deletion behaves differently from a reset. Apps asking for the identifier get back a string of zeros instead of a number. Nothing left to reset later, because nothing is there.

iPhones do not work this way at all. No reset button exists on that side. Turn off the tracking permission and the app receives zeros, which lands closer to deletion than to a rotation.

A New Number Is Not a New Person

Here is what survives the reset untouched.

Your Google Account. Every search you ran while signed in. Watch history too. The interest categories built out of all of it. None of that ever lived on the advertising ID.

Your browser. Cookies, site logins, whatever a site dropped in there last month. Unaffected.

Your email address. Hand it to a business and it can end up inside an uploaded customer list at an ad platform. That list matches you by the address rather than by any device number.

Your IP address. Same home, same connection, same rough location as yesterday.

So the ads look familiar again within a day or two. Nothing malfunctioned. You rotated one identifier out of several. Most people expect the opposite. They expect a reset to feel like clearing a browser. It never does.

Account-level controls sit at My Ad Center under your Google login. Different screen, different job. The phone reset never touches it.

Somebody Will Say the Reset Really Does Break the Link

It does. That objection is correct, and it is the strongest one available.

Google’s policy for app developers is explicit here. Connecting a reset advertising ID back to the previous one needs the user agreeing to it first. So the chain genuinely snaps. An app that spent months building a profile against the old number starts over from nothing. Frequency capping keyed to that number resets alongside it. Some in-app ad you had already dismissed a dozen times comes back around like new.

Then look at what changed on your screen. Very little. Sometimes nothing you can detect at all.

That gap is the whole answer. The reset performs perfectly. Ads barely move. Which means the advertising ID was never carrying most of the targeting. You learn that by breaking it cleanly and watching.

The Advertising ID Only Ever Governed Apps

Play services hands the identifier to apps installed on the phone. That is the boundary.

Chrome never used it. Neither did the search results on a desktop. A search ad served to you at a laptop had no idea the number existed.

So the size of the effect depends on how you use the phone. Someone living inside free apps with ad slots resets something meaningful. Anyone who mostly browses resets almost nothing.

Check the phone before guessing at it. Whatever sits on your home screen with a banner across the bottom is the category that cared.

Worth knowing before deciding whether this belongs in a monthly routine.

Buying the Ads Instead? Read It Backwards

Advertisers get the same fact with the sign flipped.

Any user can rotate that identifier tonight. Or delete it and hand your measurement a row of zeros. Nobody asks permission first. No notification arrives afterward either. Google has also spent years building replacements for device identifiers on Android.

So app-side attribution decays quietly. The numbers do not break. They just describe fewer people than they used to. The report looks identical either way.

First-party measurement holds up better under all of that. Conversion tracking on your own website. Your own CRM records. A phone call logged by whoever answered it. None of those depend on a setting the customer can flip in bed at midnight.

Most local businesses in Calgary run search campaigns rather than app installs anyway. Which means the advertising ID barely enters the reporting to begin with. Sorting out which parts of your Google Ads management actually lean on device identifiers takes about an afternoon.

SEO Company To-The-TOP! has run paid campaigns and Calgary SEO for local businesses since 2007. Solo practitioner. The person who reviews your tracking is the person who fixes it.

We treat device identifiers as the least durable input available. Conversion actions on your own site come first. Then the CRM. Whatever the platform can add sits on top of those.

Clients ask about privacy changes fairly often now. We answer plainly. Some of them will reduce what you can measure. Pretending otherwise makes the next report harder to explain. A website audit shows what your tracking depends on before any of it shifts underneath you.

Not every advertiser needs to care about this one. Our SEO services clients running search campaigns mostly do not. Finding out which side you sit on costs one conversation.

Common Questions About Resetting Google Ad ID

Does resetting the advertising ID stop personalized ads?

No. It rotates a device identifier. Personalization built on your signed-in Google Account keeps running exactly as before. Turn that part off inside My Ad Center instead.

How often should I reset my Google advertising ID?

No schedule beats any other schedule. Each reset breaks app-side profiling from that moment onward. Nothing accumulates from doing it weekly rather than yearly.

Can I delete the advertising ID instead of resetting it?

Newer Android builds offer deletion in the same menu. Apps requesting it then receive zeros. Some ad-supported apps notice and ask you to switch it back on.

Where is the reset on a Samsung phone?

Settings, then Google, then Ads on most builds. Search the word ads inside Settings if the menu sits elsewhere on your version.

Does resetting the Ad ID affect my Google Ads account?

Not at all. Your account number stays whatever it was. The advertising ID belongs to a phone. Your advertising account never had one.
