US Bank Account Setup

 Hi

There does not seem to be a cash management community to put this question to and so I am hoping someone in the Payables community can help.

In the UK to make electronic payments we need two fundamental pieces of information for the Payer :

1.  The Bank sort code.  This is entered in the Bank Branch field

2.  The Internal Bank Account Number.  This is entered in the Bank Account Number field

We also need the same information for the Payee.  Exactly the same fields are entered.

Can somebody please help and tell me what information is required for the US (Nacha format) and which fields of the bank account is the information entered.
