Remember that those are called SUPPORTING documents to prove that you have credentials on being a good paying subscriber meaning:
1. You are who you claim you are;
2. You have a valid address where they can send your bill or demand letters in case you refuse to pay and,
3. You can afford the plan you are applying for and would be able to sustain it for the period that would be indicated in the plan you are applying for.
Compliance is one, approval is another.
