Answer:
If your state follows the "standard" wording for section 4-403 of the Uniform Commercial Code (UCC), an oral stop order on a check is valid for 14 calendar days unless it is sooner replaced with a written order. A few states do not specifically provide for oral stop orders in their UCC wording. NACHA rules on stop payments of ACH transfers provide for oral stop orders, with the same 14-calendar-day period of effectiveness pending replacement by a written order.
