Identification Number for an Adopted Child

Enter your adopted child's Social Security number (SSN), Individual Taxpayer Identification number (ITIN), or Adoption Taxpayer Identification number (ATIN).

If you are in the process of adopting a child who is a U.S. citizen or resident alien but cannot get an SSN for the child in time to file your return, apply for an ATIN using Form W-7A . However, if the child is not a U.S. citizen or resident alien, apply instead for an ITIN using Form W-7 .
