Generally, taxpayers must provide SSNs for each dependent claimed on the tax return. For adopted children without SSNs, the parents can apply for an Adoption Taxpayer Identification Number, or ATIN, by filing Form W-7A with the IRS. The ATIN is a temporary number used in place of the SSN on the tax return. The form is available on the IRS Web site, IRS.gov, or by calling 800-TAX-FORM (800-829-3676). | Generally, taxpayers must provide SSNs for each dependent claimed on the tax return.
