State Directory of New Hires (SDNH)
A database maintained by each State, which contains information regarding newly hired employees for the respective State. The data is then transmitted to the NDNH, where it is compared to the employment data from other States as well as child support data in the Federal Case Registry (FCR). Any matches found are returned to the appropriate States for processing. Employers are required to submit new hire data to the SDNH within 20 days of the hire date. Multistate employers (those that do business and hire workers in more than one State) have additional options on where to report new hire information. In most States, the SDNH is contained in the State Parent Locator Service (SPLS) that is part of each State IV-D agency, in others it is operated by the State Employment Security Agency (SESA).
