Social Security - Getting a Number

You will need to file form SS-5. Contact your local Social Security office or go on the Internet http://www.ssa.gov/ssnumber/ and download the form.
If you are expecting a child to be born this year, keep in mind that you will not be able to take a deduction for your new baby without the social security number.
Most hospitals are aware of this and provide the forms along with birth records.
