What is State Employment Security Agency?
State Employment Security Agency meaning Agencies in each State that process unemployment insurance claims. They are also repositories of quarterly wage data, information on all employees submitted by employers, which they submit to the National Directory of New Hires (NDNH) along with the unemployment insurance claim data. In some States, the SESA also operates the State Directory of New Hires (SDNH), which contains data submitted by employers on newly hired employees. Data submitted to the NDNH is then compared against child support order information contained in the Federal Case Registry (FCR) for possible enforcement of child support obligations by wage garnishment.
