Agreement to Exchange Electronic Income Withholding Orders/Notices
By completing and providing the information on this form, the employer, company, or government agency agrees
that:
The employer, company, or government agency shall have appropriate procedures in place to promptly report
confirmed or suspected information security or privacy incidents, including, but not limited to, unauthorized use or
disclosure of Personally Identifiable Information (PII) involving confidential child support information submitted
through OCSE to your organization. As soon as reasonably practicable after discovery, but in no case later than one
hour after discovery of the incident, the employer, company, or government agency shall report confirmed or
suspected incidents to OCSE as specified in this paragraph. The requirement for the employer, company, or
government agency to report confirmed or suspected incidents involving PII to OCSE is based on federal
guidance/requirements from the Office of Management and Budget (OMB), Health and Human Services (HHS), the
Federal Information Security Modernization Act of 2014 (FISMA), and the United States Computer Emergency
Readiness Team (US-CERT).
Incidents must be reported via email to OCSE using the security mailbox address:

The organization will electronically receive and respond to IWOs issued by states, tribes, or territories in the
same manner as mailed notices within the required timeframes. Response timeframes and other
instructions are available at
https://ocsp.acf.hhs.gov/irg/irgpdf.pdf?geoType=OGP&groupCode=EMP&addrType=EIW&addrClassType=E
MP
The organization will not impersonate any individual, entity, or association; use false headers; or
otherwise conceal or provide misleading information about their identity while receiving IWOs
electronically.
The organization’s representative completing this form is authorized to act on behalf of the employer
and agrees to provide true, correct, current, and complete information about the entity identified in
the profile form.
The organization will consider the electronic version of the IWO admissible as evidence in the same way as paper
documents.
The organization will provide written notice to the federal Office of Child Support Enforcement at least 30 days before
it intends to stop accepting e-IWOs.
A third-party provider certifies that it has authorization to participate in e-IWO on behalf of their clients and will
provide company names, FEINs, and related information to OCSE for the purpose of processing e-IWOs.

File Naming Convention
Files can be named using OCSE’s standard file naming convention or the organization’s file
naming convention. The naming convention for PDF files is standard for this process:
1. In the Standard/Organization-Supplied File Naming Convention column, select whether you want to use your

organization’s file naming convention or OCSE’s standard file naming convention.
2. In the File Naming Convention column, take the following steps:
– If you are using your organization’s file naming convention, enter the file naming convention. For
example, for the file with notices (Incoming State Notice Files), you can enter
enmsn.mybiz.notices.txt. This is the name of the file you will receive that includes your notices.
– If you are using OCSE’s standard file naming convention, an example file name is in the table below. For
more information about file naming conventions and formats, refer to the e-NMSN Software Interface
Specifications.
