I'm trying to order checks for the first time, and the check provider is asking for me to provide a routing number and checking account number, both provided by my bank. However, they're also asking for the "fractional form" of the routing number, which is not provided by my bank, and which I can't look up on a check. (This is my first time ordering checks from this bank)
Is there some way to generate the fractional number given the MCIR routing number?
(Even Bank of America's Own Site lists the routing number 051000017, but the fractional number is the placeholder 123456789)
