RM 10210.305 Reviewing a Birth Certificate Birth Area Code

A. Information about the birth area code

Since 1948, most State registrars use a uniform numbering system.

Birth certificates (BCs) issued by the States generally include an 11-digit number in a xxx xx xxxxxx format. The number begins with a 3-digit birth area code number followed by a 2-digit year of registration (almost always the year of birth) and lastly a 6-digit serial registration number (assigned sequentially to each birth as it is filed).

B. Procedure for reviewing the birth area code

Follow this procedure in conjunction with RM 10210.210, Reviewing Age, Identity, Citizenship and Lawful Alien Status Evidence for an SSN Card.

  1. 1. 

    Compare the 3-digit birth area code with the birth area code(s) listed below.

  2. 2. 

    Compare the serial registration number with the date of birth. Registration numbers issued early in the year should have a low registration number although it would be unlikely for a birth at the end of the year to have a low registration number.

  3. 3. 

    Verify any BC with the issuing agency when the birth area code number does not agree with the assigned birth area code number. Follow GN 00308.000 and/or local procedures to verify primary evidence of age with the appropriate BVS. For additional information regarding suspect or fraudulent birth records, see RM 10210.700 and regional fraud reports.
