SF-424 Mandatory Form
In accordance with policies for mandatory grant programs, state child support agencies must submit the SF-424M by the end of the fiscal year through the On-Line Data Collection (OLDC) system. The SF-424M captures important grant information, such as the Data Universal Numbering System (DUNS) number. States may submit the SF-424M when other required reports are due in the OLDC system, such as the OCSE-34A, 396A, or 157.
