The Quick Reference Guide to which Chris has linked was last updated in 2002. It includes outdated information. For example, POP and ARC (and soon, BOC) transactions can be used for business checks up to $25,000 if they don't have an auxiliary on-us field. Also, the ARC and POP entries cannot exceed $25,000.
The adjusting return entry code for stops on a missed paper check stop that affects and ARC is R38, not R08. And the retention period on checks converted to ARC entries is now extended beyound 14 days (as long as the paper check can be retained securely).
