If you are in the US they will ring, if not they will approve you but do an automatic call with a PIN number that you need to enter to verify details.
Also, I spoke to my AM about the ID, I wasn't asked for one but you may need to send one in; it is simply to eliminate those people that want to come in and rob advertisers = fraud.
They're a good company with support, if you're in the US don't let the call put you off joining them!
