Why do doctor's medical forms ask you for your Social Security Number?

Answer by  John (9008)

It is a convenient number for them to use to keep track of your records. Also, since every doctor and hospital uses it, it creates a standard number for all patient records. Lastly, your insurance is likely to require that it be provided to prove your identity.
