Aha - well that might be interesting - B of A is just so wonderfully easy to contact and get answers from! I will try that. Interesting that they don't provide that on their website.

I looked up the routing numbers for ACH in Washington and I have the right one. The one showing for Oregon (the tax region) is very different but it will not meet the requirements stated in Proconnect (starts with 1 or 12). (That bothers me somehow--12 starts with 1). Anyway. Not sure where to go from here. Hold times for B of A are up to 2.5 hours.
