Auxiliary On-Us Field

A field on the magnetic ink character recognition (MICR) line of a check or share draft. This is an optional field that can be found to the left of the routing number. The presence of this field makes the check in-eligible to be used as a source document for accounts receivable conversion (ARC), back office conversion (BOC), and point-of-purchase (POP) entries.
