The Birth Certificate Number (USA)

For instance 139 -67-123456

For instance 123456-67


On any given day the numbers are assigned by the local county Health Department. Often the births are sorted in alphabetical order prior to assigning the number. This can be helpful. It would be nice if this number were related to the Social Security Number.

It appears as though not all states adhere to the federal system, namely NH, PA.

The numbers with a question mark are states that cannot be verified. It appears as though MD and NY issue a completely new number to adoptees. The fourth and fifth digits in the bc number signify the year on all.

The explanation given from an IL hospital is the last six numbers are sequential numbers issued to hospitals in group lots of a given number, ie, Jones Hospital would get 000001 thru 000500, and Smith Hospital would get 000501 thru 001000. When the hospital uses up all its assigned numbers it requests more from the state.
