the social security number (SSN) for your adoptive child if the IRS provided an ATIN for your adoptive child.

Security Administration (SSA) can assign a SSN.

office, or by calling the SSA at 1-800-772-1213. It usually takes about 2 weeks to get an SSN once the SSA has all the evidence and
information it needs.
Application for SSN denied. If the SSA denies your application for an SSN, contact the IRS to request an extension or reactivation of
the ATIN. When you request the extension or reactivation of the ATIN, include the SSA’s denial letter or an explanation with your
How Long Can You Use an ATIN
After the adoption is final, don't continue using the ATIN. Instead use the Form 15101, Provide a Social Security Number (SSN) for
Adoptive Child, to provide the SSN received for the adoptive child.
