The child support service called the IV-D (4-D) Program is a federal, state, and local effort to collect child support from parents who are legally obligated to pay.
Established in 1975 as Title IV-D (4-D) of the Social Security Act, the child support enforcement program functions in all 50 states and some foreign countries as well.
Through the IV-D Program absent parents can be located, parentage can be established, and support orders can be enforced to ensure child support payments.
Either of the following phone numbers for the Illinois Department of Healthcare and Family Services, can be used to make an appointment for enrollment into the IV-D program. You do not need to be on public aid to receive child support services. The department is simply the administrator of child support for the State of Illinois.
