If you are the Key Contact for your organization, you should be receiving the complimentary copy of the 2026 Nacha Operating Rules & Guidelines in the mail very soon. As an added benefit, SFE provides tabs for frequently used pages in the Rule Book.
You can access the reference guide for tabbing in the Member Resources/Quick Reference/ACH Tools section of sfe.org, once you are logged in to your profile. If you need assistance logging in, please reach out.
