I mailed mine in and forgot the utility bill as proof of address, I wrote customer service when I realized and they repsonded that I could scan and email. This was not a problem and account was approved quickly once I did this, however I will say when I sent that utility bill I sent all of the documents with so there wouldn’t be confusion as to who they belonged to etc. I found customer service to be doing a terriffic job and can’t wait til this is all rolling.
