Can anyone explain to me the term? One of our customers has asked us about this, having heard it from the automated system while making their Federal Tax deposit. Thank you in advance.

We've received a lot of questions about this too. I'm not sure but I think some institutions may block certain ACH transactions by tran code...maybe their not an ACH participant or maybe they're just an ODFI or RDFI.
Someone correct me if I'm wrong here!!

I always figure, if you don't know what it is, ya don't got it.

VISA allows us to prohibit payments to certain companies by filtering on SIC codes. We use this option to prohibit payments to offshore betting and gambling facilities.
