Birth Certificate Number: Format, Meaning & Where to Find It

What is a Birth Certificate Number?

A birth certificate number is an 11-digit identification number found on official U.S. birth certificates. Each number is unique and assigned when the birth certificate is registered with the state’s Vital Records Office.

This number is essential because it serves as official proof of birth and is required for legal and identification purposes, including:

  • Obtaining a passport
  • Applying for a driver’s license
  • Verifying identity for legal documents
  • Requesting a birth certificate replacement

Birth Certificate Number Format & Breakdown

The birth certificate number follows an XXX-XX-XXXXXX format and consists of three main parts:

1. 3-Digit Area Code Number

This represents the state or territory where the birth was registered. Each state has a designated code.

2. 2-Digit Year of Registration

This typically corresponds to the year of birth or the year the birth was recorded in official records.

3. 6-Digit Serial Registration Number

This is a unique sequential number assigned to each birth certificate upon registration.
