Announcing amendments to Operating Circular 3 (OC 3)

October 15, 2021

Effective November 15, 2021 the Federal Reserve Banks are amending Operating Circular 3, Collection of Cash Items and Returned Checks to include a new Appendix I: FedDetectSM Duplicate Treasury Check Notifier Service. The new service will offer banks of first deposit (BOFDs) early notice of potential duplicate U.S. Treasury checks processed by the Federal Reserve Banks.

Please see the Operating Circulars page on FRBservices.org® for more information, including the amended operating circular. Your continued use of the Check Services on or after November 15, 2021 constitutes agreement to the amended Operating Circular 3.
