Multistate Financial Institution Data Match Specifications Handbook

Version 3.0

Publication Date: December 30, 2020

In 1996, the federal government mandated the Financial Institution Data Match (FIDM) program. It resulted in a partnership between the child support program and the nation’s financial institutions to identify financial accounts belonging to delinquent obligors. It requires each state to implement quarterly matching of delinquent noncustodial parents to the accounts maintained at financial institutions.

This handbook establishes the specifications used to conduct this match. The data match specifications provide detailed information on the programming necessary to process and return files.
