If you’re publishing an app on behalf of a client, the chances are your app will be suspended from the Play Store by Google due to a violation of the impersonation policy. The reason for this is that Google is unable to link the name of your clients app to the name of your developer account.
What you can do to prevent this, is to send Google an advanced notice of the app you’re publishing. With this advanced notice, you can provide a document containing a written statement from your client, allowing you to publish the app with the content it holds.
Filling out an advanced notice can be done through the following form:
The default format for a package name is com.app.p[appnumber]. This means that the app with app number 1234AB will receive the following package name: com.app.p1234AB
The app number of your app can be found on the Dashboard page of your app in AppMachine.
