6. e-NMSN FEIN Push

Currently, employers, third-party providers, and plan administrators provide the Federal Employer Identification Number (FEIN) in an Excel worksheet for all the subsidiaries they will receive and respond to National Medical Support Notice (NMSN) orders. These FEINs and the relationships between the organizations are then stored on the e-NMSN Office of Child Support Services (OCSS) system and sent to states so states will know which FEINs to use for each employer.

Employers and third-party providers must keep their FEIN information up-to-date to receive e-NMSNs for only the companies and organizations they process medical support notices. It is also critical that states receive the latest FEIN information for all employers and third-party providers to ensure they send e-NMSN orders only to FEINs for companies and organizations specified in the employers or third-party providers’ FEIN list. This process provides states with active and inactive FEINs participating in the e-NMSN process.

To accommodate the need for an automated solution for receiving and sending FEIN information, an FEIN Push process was developed. States can receive FEIN information electronically in the FEIN file layout described in Chart F‑1. States choosing to receive FEIN information from this automated process must provide a filename in the e-NMSN Profile so the information can be sent to them in the specified file. For more information about the FEIN Push filename, see section F.1, FEIN Push File and Format.

Currently, states can only receive FEIN file information through this FEIN Push process. The Portal pushes the FEIN file on the 8th and 25th of each month.

An FEIN Report file is created by the Portal for any state to use. This file contains active and inactive employer FEINs. When an employer notifies the Portal that it no longer processes e NMSNs for a particular FEIN, this FEIN is categorized as inactive.

1. FEIN Push File and Format

This section describes all components of the FEIN file pushed to states. This includes a data element description, the file layout and format rules, an example FEIN file, and file naming conventions.

The FEIN file is generated in a fixed-length format. Chart F‑1 specifies the lengths and locations of each data element in the file.

The following list is a summary of the formatting rules:

• Each employer’s data is on a separate line.

• Each data element has a fixed length.

• Data elements on the FEIN Push file are in the same order they appear in the e-NMSN FEIN Push file.

2. e-NMSN FEIN Push File Record
