The Green Book is a comprehensive guide for financial institutions that receive ACH payments from and send payments (i.e. collections) to the federal government.
Most federal payments are made through ACH with very few exceptions.
Federal government ACH transactions continue to be subject to the same rules as private industry ACH payments.
The Green Book is designed to deal primarily with exceptions or issues unique to federal government operations.
The Green Book contains federal agency contact information and website addresses where appropriate.
To make the Green Book easier to navigate, download, and print, chapters are available in PDF format only.
We periodically review and update the Green Book.
