Birth Certificate Number

All U.S. birth certificates have an 11-digit identification number, written in XXX-XX-XXXXXX format. The birth certificate number is generated using the:

• 3-digit area code number.
• 2-digit year of registration (usually the year of birth)
• 6-digit serial registration number (assigned sequentially)

In nearly every state, the birth certificate number will be in the top right-hand corner of the birth certificate copy.
