How to Request the Record When It's Not Online
Statewide registration for births started in 1907. General compliance year is unknown. To learn more about record limitations and restrictions, see the article How to Find Colorado Birth Records. To order birth records after 1907, contact:


 * Colorado Department of Public Health and Environment 4300 Cherry Creek Drive South Denver, CO 80246 Phone: (303) 692-2200 Website

NOTE: By law, only the person on the certificate, close relatives, or an authorized genealogist may order a birth certificate (see Restrictions for more details).

Additional Records with Birth Information
Substitute records may contain information about more than one event and are used when records for an event are not available. Records that are used to substitute for birth events may not have been created at the time of the birth. The accuracy of the record is contingent upon when the information was recorded. Search for information in multiple substitute records to confirm the accuracy of these records.

Tips for finding births
Successfully finding birth records in online databases depends on a few key points. Try the following search suggestions:
 * Spelling variations. Your ancestor's name may be misspelled. Search with spelling variations for the first and last name of your ancestor.
 * Search parents. Search for the parents, if known, as the child's first name may not be on the birth record.
 * Search given name. Search by given name (leave out the last name) with the approximate date of birth.
 * Add information. For common names, add more information to narrow the search such as approximate birth date or parent's names if known.
 * Date range. Expand the date range of the search by 5 years.
 * Search state. Search using the state name only instead of by county.
