A: Financial Organization Master File (FOMF)

The Financial Organization Master File (FOMF) is a Department of the Treasury master list of 

financial institutions receiving federal government ACH payments. It contains RTNs, a single 

financial institution name and mailing address for each RTN. 

The FOMF is derived from the Federal Reserve Bank’s (FRB) ACH Customer Directory (ACD), which 

contains the RTNs and related information of all valid ACH participants. The FOMF is updated on a 

monthly basis using information from the most current ACD file. 

Purpose

The Fiscal Service relies on the FOMF data to validate RTNs used to originate payments and to send 

financial institutions the following: 

x reclamation notices, 

x trace inquiries, and 

x marketing materials. 

Financial Institution Responsibility

Changes to Financial Institution Name and Mailing Address

Financial institutions are responsible for keeping their name and mailing address for each RTN up 

to date with the FRB. Any changes to RTN data should be provided to the FRB as soon as possible so 

that the ACD and FOMF contain current data. If the financial institution fails to notify the FRB, it 

may be held liable for information (e.g., reclamation notices) mailed to obsolete addresses. 

Changes to Routing Transit Numbers

If a financial institution changes RTNs (e.g., due to merger), it must notify the FRB ACH department 

as soon as possible to have the old RTN rescinded in ACD and have all future ACH transactions 

reflect the financial institution’s active ACH routing number. Updates to the ACD will update the 

FOMF. Additionally, financial institutions should send a Notification of Change (NOC) to each 

originating federal agency from which it receives payments impacted by the routing number 

changes. 

The following steps should be taken in updating the ACD routing number data: 

x Confirm that no activity is being received on the obsolete RTN prior to deletion. 

x Allow at least three months after the update to the ACD before deleting an obsolete RTN. 

x Delete an obsolete RTN only after all activity has been transferred to the surviving RTN. 

Updating ACH Customer Directory (ACD):

If an institution wants to update the information that appears on the file, they should submit a new 

“Part 1 - Agreement to Terms and General Participant Information” of the FedACH Participation

Agreement to the FRB. 

If you have any questions in reference to updating data, you should contact the FedACH and Check 

Services Customer Support team. 
2. ACH Payment Processing Green Book

2-4 A Guide to Federal Government ACH Payments

New Depository Institutions

Because the FOMF is updated monthly, a new depository institution may not receive government 

ACH transactions for up to 30 days after being entered into the FRB ACD. 

B: Federal Government ACH Processing

General Flow

Federal government ACH payments are initiated by the authorizing federal agency to a government 

disbursing office. These include the Department of Defense disbursing offices, and Fiscal Service. 

The FRB is the federal government’s ACH Operator. 

Prenotification

The federal government prenotification process is handled in accordance with Nacha Operating 

Rules & Guidelines. Social Security Administration originates prenotifications for Social Security 

benefits for Direct Deposit enrollments and changes. 

Payment Formats

Federal government ACH payments are originated in the Prearranged Payment and Deposit (PPD) 

with or without addenda, Corporate Credit or Debit (CCD) with or without addenda, Corporate 

Trade Exchange (CTX) formats, or International ACH Transaction (IAT). Refer to the Nacha 

Operating Rules & Guidelines for details on payment record formats. 

Account Requirements

All federal government benefit payment enrollments must be established for a deposit account at 

the financial institution that is in the name of the recipient or beneficiary with the following 

exceptions: 

x Where an authorized payment agent (representative payee) has been selected, a representative 

payee is an individual or organization appointed by SSA to receive Social Security and/or SSI 

benefits for someone who cannot manage or direct someone else to manage his or her money. 

The main responsibilities of a payee are to use the benefits to pay for the current and 

foreseeable needs of the beneficiary and properly save any benefits not needed to meet current 

needs. A payee must also keep records of expenses. 

x Where the payment is to be deposited into an investment account established through a 

securities broker or dealer registered with the Securities and Exchange Commission, or an 

investment account established through an investment company registered under the 

Investment Company Act of 1940 or its transfer agent, the payment may be deposited into an 

account designated by the broker or dealer, investment company, or transfer agent. 

• Where a federal payment is disbursed to a resident of a nursing facility, as defined in 42 U.S.C. 

1396r, the payment may be deposited into a resident trust or patient fund account established 

by the nursing facility so long as it meets the requirements under federal law relating to the 
Green Book 2. ACH Payment Processing

A Guide to Federal Government ACH Payments 2-5

protection of such funds. For more information on these requirements, please visit the ACH 

regulations website. 

• Where a federal payment is disbursed to a member of a religious order who has taken a vow of 

poverty, the payment may be deposited to an account established by the religious order. The 

phrase ‘member of a religious order who has taken a vow of poverty’ is defined as it would be by 

the Internal Revenue Service for federal tax purposes. 

• Where a federal payment is to be deposited to an account accessed by the recipient through a 

prepaid card that meets the following requirements: 

(A) The account is held at an insured financial institution, 

(B) The account is set up to meet the requirements for pass-through deposit or share insurance 

such that the funds accessible through the card are insured for the benefit of the recipient 

by the Federal Deposit Insurance Corporation or the National Credit Union Share Insurance 

Fund in accordance with applicable law (12 CFR part 330 or 12 CFR part 745), 

(C) The account is not attached to a line of credit or loan agreement under which repayment 

from the account is triggered upon delivery of the federal payments, and 

(D) The issuer of the card complies with all the requirements and provides the holder of the 

card with all the consumer protections, that apply to a payroll card account under the 

rules implementing the Electronic Fund Transfer Act, as amended. 

No person or entity may issue a prepaid card that receives federal payments in violation of these 

requirements, and no financial institution may maintain an account for or on behalf of an issuer 

of a prepaid card that receives federal payments if the issuer violates these requirements. If 

Fiscal Service becomes aware that a prepaid card product that accepts federal government 

payments does not meet these requirements, it will research the card product and report any 

violations of these requirements to the institution’s primarily regulator. 

• Where Treasury has granted a waiver. 

Misdirected Payments

. The RDFI decides to manually post the misdirected payment to the correct account and originates 

an NOC entry with the correct account and/or RTN information. Please note that the financial 

institution does this at its own risk and may be liable to the issuing agency if the financial 

institution post the misdirect payment to an incorrect account and there is a resulting loss by the 

agency. Please see Chapter 6, Notification of Change, for more information. If the financial 

institution cannot credit the misdirected payment to the correct account, the financial institution 

may return the payment to the agency with an appropriate reason code. Please see Chapter 4, 

Returns, for more information. 

It is important to note that a financial institution is not required to manually verify that the name on 

the ACH entry matches the name on the account at the time the payment is posted. An RDFI is only 

liable for posting the payment to the account in the ACH credit entry. 
2. ACH Payment Processing Green Book

2-6 A Guide to Federal Government ACH Payments

Notice of Misdirected Payment

In accordance with 31 CFR part 210, an RDFI that becomes aware that an agency has misdirected 

an ACH credit entry to the wrong account must promptly notify the agency. A financial institution 

may become aware of a misdirected payment through the following ways: 

x The account holder notifies the financial institution of the misdirected payment, 

x A non-receipt claim being investigated by Fiscal Service, 

x A financial institution that manually posts their ACH credits notices that a payment is being 

credited to the wrong account. (It is important to note that an institution is not required to 

match names when posting a federal government ACH entry; however, if it routinely posts 

entries manually and notices that an entry is being directed to the wrong account, it is required 

to notify the agency.), and 

x A call from the federal agency that disbursed the payment. 

If a financial institution becomes aware of a misdirected payment, it can notify the agency in the 

following ways and meet the requirements of 31 CFR part 210: 

x The RDFI decides to manually post the misdirected payment to the correct account and 

originates an NOC entry with the correct account and/or RTN information. Please note that the 

financial institution does this at its own risk and may be liable to the issuing agency if the 

financial institution is incorrect and there is a resulting loss by the agency, 

x Return the original ACH credit entry to the agency with the appropriate return reason code, 

x Contact the agency by phone or by letter. Please see Chapter 7, Contacts, and 

x Any other means deemed acceptable by the agency that disbursed the ACH credit payment. 

Availability of Funds

In accordance with Nacha Operating Rules & Guidelines, any non-Same Day ACH credit payment 

must be made available for withdrawal by the Receiver no later than 9:00 a.m., Receiving 

Depository Financial Institution (RDFI) local time, on the settlement date (provided the entries are 

made available to the RDFI by its ACH operator no later than 5:00 p.m. on the banking day prior to 

the settlement date). 

On January 03, 2022, the Fiscal Service accepted the Nacha rule changes that allow for Same Day 

ACH transactions, and effective March 22, 2022, Fiscal Service amended 31 CFR Part 210, to 

address changes made by Nacha through the 2021 Nacha Operating Rules & Guidelines book, 

including supplements thereto. 

Same Day ACH rules have established three windows for all financial institutions to submit Same 

Day ACH payments: 10:30 a.m., 2:30 p.m., and 4:45 p.m. ET. Fiscal Service only uses the second and 

third windows for same day ACH transactions. Funds from Same Day ACH credits processed in the 

second processing window will be made available by 5:00 p.m. RDFI’s local time, while funds from 

Same Day ACH credits processed in the third window are settled at 6:00 p.m. ET. The amount of a 

third window Same Day ACH credit must be available to the receiver’s account no later than the end 

of the RDFI’s processing day (RDFI’s local time). Such funds are not required to be 

available for 

withdrawal on the settlement date. There is a $1,000,000 per payment limit for Same Day ACH that 

applies to all Fiscal Service payment customers. 
Green Book 2. ACH Payment Processing

A Guide to Federal Government ACH Payments 2-7

Non-Treasury Disbursed Organizations, who do not submit their payments through the Fiscal 

Service, are currently prohibited from authorizing any Same Day ACH credits for payments. Only 

agencies that disburse through the Fiscal Service will be permitted to request Same Day ACH 

payments. Fiscal Service began to process Same Day ACH credits (for payments) in April 2018. The 

Fiscal Service began to accept Same Day ACH credits and debits for tax collections beginning in 

September 2017. 

C: Federal ACH Payment Schedule

Fiscal Service publishes the federal ACH Payment Schedule annually on the Fiscal Service website. 

This listing provides the actual payment date for recurring federal payments. The payment date 

equals the ACH settlement date. RDFIs are liable for provisional payments made in advance of 

settlement date and may use their own discretion posting provisional payments to accounts 

D: Identifying Treasury Disbursed Payments

Consumer Payments

Consumer Payment Formats

Consumer payments are designated for deposit into an individual’s account. They are identified by 

the Standard Entry Class (SEC) code to be used for consumer entries which is found in the 

Company/Batch Header Record (Field 6) of the payment file data. (Note: If the correct format is not 

used, the payment should be returned.) 

Standard Entry Class Code

The Prearranged Payment and Deposit (PPD) is the SEC code used for identifying federal agency 

consumer payments. The payment entries may be accompanied by a PPD addenda record (PPD+) 

which further identifies the reason for the payment. 

Social Security Administration Use of Prearranged Payment and Deposit (PPD+)

For Direct Deposit of Representative Fee Payments and Direct Deposit of Representative 

Payees/Organizational Representative Payees 

The Social Security Administration (SSA) issues fee payments either by check or direct deposit to 

individuals who have represented Social Security claimants and/or act as a representative payee. 

SSA has begun to use the PPD+ format for ACH payments to representatives that include adequate 

payment-related information that can be passed onto them to identify and credit the payment to 

the correct person/account. The information is included in 9 + rtn of the Addenda Record (Payment 

Related Information) and is based on ANSI X12 (American National Standards Institute coding for 

Electronic Data Interchange) syntax. 

Fiscal Service encourages RDFIs to pass through to their account holders, as quickly as possible, 

pertinent information from both the Entry Detail Record and the Addenda Record when a payment 

is received. The representative needs this addenda information to reconcile their client account 

records. The method of providing this information to the account holder is at the discretion of the

financial institution and its customer.

2-10 A Guide to Federal Government ACH Payments

F: Garnishment of Federal Ƥ

Garnishment is the execution, levy, attachment, or other legal process involving a written 

instruction issued by a court, a state or state agency, a municipality or municipal corporation or a 

state child support enforcement agency. This includes a lien arising by operation of law for overdue 

child support or an order to freeze the assets in an account, to impact a garnishment against a 

debtor. 

Financial institutions are subject to the requirements of title 31 of the Code of Federal Regulations, 

part 212 (31 CFR part 212) which requires financial institutions to take certain actions upon 

receipt of garnishment orders. 

Fiscal Service has published the document “Guidelines for Garnishments of Accounts Containing

Federal Benefit Payments” that financial institutions can reference when a garnishment order is 

received for an account into which federal benefit payments have been directly deposited. 

Financial institutions that receive a garnishment order are required to determine the sum of 

protected federal benefits deposited to the account during a two month period, and ensure that the 

account holder has access to an amount equal to that sum or to the current balance of the account, 

whichever is lower. 

Title 31 CFR part 212 applies to the following federal programs: 

x Social Security and Supplemental Security Income benefits administered by the Social Security 

Administration; 

x Veterans benefits administered by the Department of Veterans Affairs; 

x Federal Railroad retirement unemployment and sickness benefits administered by the 

Railroad Retirement Board; and 

x Civil Service Retirement System and Federal Employee Retirement System benefits 

administered by the Office of Personnel Management. 

To assist financial institutions, Fiscal Service is encoding an “XX” in Positions 54-55 of the 

“Company Entry Description” field of the Batch Header Record for ACH/PPD and ACH/CCD 

payments that are designated as federal benefit payments that are exempt from garnishment. This 

encoding allows financial institutions to determine whether a federal direct deposit payment is an 

exempt federal benefit payment. Financial institutions may rely on the presence of an “XX” 

encoded in Positions 54-55 of the “Company Entry Description” Field to identify a federal 

benefit payment exempt from garnishment. 

EXAMPLES: 

Company Entry Description (Positions 54-63) 

Benefit Payment Type Prior to the Garnishment Rule With the Garnishment Rule 

Social Security SOC SEC XXSOC SEC 

Supplemental Security Income SUPP SEC XXSUPP SEC 

Railroad Retirement RR RET XXRR RET 

Because it is possible that a commercial payment could also have an “XX” encoded in Positions 54- 

55, financial institutions must verify that the payment is a federal payment. This can be confirmed 
Green Book 2. ACH Payment Processing

A Guide to Federal Government ACH Payments 2-11

either by searching for a “2” in the “Originator Status Code” Field in the Batch Header Record 

(Position 79) OR by reviewing the description of the payment in the ACH Batch Header Record 

Company Entry Description to ensure that the payment is one of the exempt federal benefit types 

shown in the Fiscal Service publication “Guidelines for Garnishments of Accounts Containing

Federal Benefit Payments”.
