If you have an old admin account for Google Apps and you can't sign in, try this little trick that just worked for us.
We had a phone number set as our primary verification method, but when we went to sign in, we were getting an error that the system was unable to send us a verification message and that our mobile number was recently changed; even though it was not.
As such, we could not get a verification code to sign in. We spent multiple hours searching for a solution, but none worked. Until we decided to try and use the account recovery feature of Google and we just went through the steps. We basically changed nothing since we already know our username and password.
As soon as that was done, Google Apps now properly sent us a verification code to our mobile, and we were able to successfully sign in. Hurray!
Maybe our Google Apps account is ancient, and the recovery process refreshed some necessary snippets in their databases, allowing them to properly send the code. Maybe it was something else. In all cases, it did work.
Hope this helps anyone who might be having the same issue.
