I'm going to call a VA phone number that is supposedly for 'Direct Deposit'. I am wanting to change the bank routing number. I was previously advised to send a 'Statement in Support of Claim' and may still do that. But am wondering if I call this number,and by some chance it's the right number to call, does the Authorization give me the right to make such a change and more to the point how does the person on the other end know I do have an Authorization to Disclose already on file ? Thank you!
