Though it may seem strange that your tiny baby needs a Social Security number, it's true: You'll need this right away to claim child-related tax breaks, add your baby to your health insurance plan, set up a college savings plan or bank account for your little one, or apply for government benefits for your child.

The easiest way to apply is by completing a birth registration form, which has a box you can check to get a Social Security number. Hospitals usually distribute them while the mother is still a patient. If you've already done that, you're all set.

If you didn't deliver your baby in the hospital or if for some other reason you were never given a form to complete, you'll need to fill one out. You can visit your local Social Security Administration (SSA) office and request a number in person. Find out more about your baby's Social Security number.
