The package name of an Android app uniquely identifies your app on a device.
When you set up an app in AdMob, your AdMob app will use the same package name as your Google Play Store app if you link the app to the Play Store. If your app shares the same package name in other third-party stores, make sure that you also select those stores when setting up your app in AdMob. If you use a different package name for the app on other Android stores, we recommend that you create a separate AdMob app for each.
Find an app's package name
Google Play Store
You can find an app's package name in the URL of your app's Google Play Store listing. For example, the URL of an app page is play.google.com/store/apps/details?id=com.example.app123. The app's package name is com.example.app123.
Other supported Android stores
For these stores, the package name can be found in the AndroidManifest.xml file of the Android app APK. For some stores, such as Amazon, the app ID is not the same as the package name.
For additional help finding your app's package name, refer to your third-party app store's documentation.

Change your app's package name in AdMob
When you set up an app in AdMob, you must add a package name. Package names are critical for ad serving. If you need to change your app's package name after you enter it, you can update it from the 'App settings' page:
- Sign in to your AdMob account at https://apps.admob.com.
- Click Apps in the sidebar.
- Select the name of the app.
- Click App settings.
- In the App store details section, click to edit
.
- Click Clear store details.
- If your app is listed in Google Play, search for your app by app name, developer name, app ID or app URL. Click Add next to the app you want to add. The package name will be automatically populated. Note: Select any other third-party stores your app is listed in before saving.
- If your app is only listed in supported third-party stores (not in Google Play), select the third-party stores. Click Edit and enter the package name. Then, click Apply.
- Click Save. Note that changing the store or package name may prompt an app readiness review and temporarily limit ad serving in the app.
- Click Confirm.
Note: If you change your package name and the prior package name was serving ads, it may temporarily appear in your Apps to confirm page.
Additionally, if you haven't set up your app in AdMob with the package name, but the package name is serving ads, you may also see this app in your Apps to confirm page. You can finish setting up the app from the Apps to confirm page or add the package name to an existing app using the steps above.
