The Problem
While trying to publish a new .apk file to the Google Play Store, you may encounter the following message:
You cannot publish applications until you complete ID verification. More details have been sent to your email.
You are likely the account owner if you see this message, and it’s likely that it’s your first time publishing an app to this account.
The Solution
Google likes to validate your identity in order to prevent fraud. You should have received an email during the registration process that asks you for a photo of a government issued document. You can see more details from Google here.
