Are you filing a joint return.  If so it requires both SS.

If you are a US citizen and your spouse does not have a Social Security number or an ITIN and you are not applying for an ITIN with the tax return then you can only use the Married Filing Separately filing status when you file your tax return.   

Where you are asked to enter the spouse's Social Security number enter 999-88-9999.  You can only print and mail your tax return; it cannot be e-filed.  When you print the tax return erase the Social Security number for your spouse and manually enter NRA for non-resident alien.
