ATINQ Overview

2.3.71.2 (01-01-2009) ATINQ Overview The Adoption Taxpayer Identification Number (ATIN) System has been developed to assign a unique temporary tax identification number for children who are in the process of being adopted and cannot yet apply for a SSN until the adoption is final. Taxpayers will submit a Form W–7A (Application for Taxpayer Identification Number for Pending Adoption) in order to acquire a number for the adoptive child. The ATIN System will consist of two command codes and various batch programs. All update processing will take place at the Austin Campus. Command code ATINQ for research of the ATIN file is described in this IRM. ATINQ is automatically routed so all service centers can research the Austin Campus file. See IRM 2.4.50, Command Code ASIGN, for updating the ATIN file.

2.3.71.3 (01-01-2008) ATIN TIP CC ATINQ This command code is used to research the ATIN. Universal access can be used to access the ATIN database at the Austin Campus if necessary. The input for ATINQ can be the primary SSN, secondary SSN, or ATIN.
