About the Records
Births in Colorado were not officially registered with the State until approximately 1908. Before that time there is no guarantee that a record of a birth exists. A few counties recorded births during that time. And in 1908 the State began recording “delayed births”, which retroactively document some births before 1908.
Birth records must be 100 years old before they are available for public access.
How to Find Information
Types of birth records held by the Colorado State Archives
- Birth Certificate - This document holds information pertaining to a single birth. They are official government records created at the time of the birth. Usually contains: Name, place of birth
- Birth Record, Ledgers, Dockets, or Books - These records collect information pertaining to many births. Each birth is a single entry among many entries usually in a bound volume. They are official government records created at the time of the birth. They usually contain information similar to a birth certificate.
- Delayed Birth Records/Certificates - Similar to their non-delayed counterparts, the only difference is their delayed creation. They are official government documents created months or years the birth.
