insurance groups lists

For those with United Heathcare, HELP Where to find the policy number?
I have to complete an application for financial assistance for my son and asks me my health insurance policy number. My card does not indicate a policy number. Simply: serial number of the group of subscribers and number one card is the policy number?! Thanks in advance!
Subscriber is a policy of # #. (Do not listen dude # 1)
