I don't see how these rules apply to need validation. If they are just being transferred over and are already existing accounts, it doesn't seem to need any validation. These accounts, while they may be new to the processor, have a documented history with your client. I would think that would allow them to just convert them over.
From the NACHA rules page linked on the Stripe page, this part seemed to make sense.
If a WEB debit customer authorizes use of an account number that has been previously used successfully for WEB debits, must an Originator do additional validation of that account number?
No. Use of an account number with a proven history of prior successful payments is a sufficient means for validation for use of the account with a new WEB authorization.
I'm not familiar with Stripe or these processes, but if that were the case, no one would ever be able to move over direct debits if changing processors. It makes sense that new accounts would need to go through validation, but this does not seem to apply to the rules as written.
