DNA Expungement Instructions

Qualifications and Instructions for Removal of an Arrestee DNA Sample


DNA samples are collected from all adults arrested for felonies. The DNA profile will be entered into the DNA database once a person is charged with a felony. Under certain conditions, the person may apply to have their DNA sample removed. The removal of a DNA sample from the DNA database is called “expungement”. You will qualify for sample expungement under the following conditions:

1. Samples on file where the charges were dismissed, the case was acquitted, or the conviction for the offense was not a felony.

(There must be a final court order for the above.)

2. Samples collected where no charges are filed or a felony charge was not filed within ninety days of arrest.

Expungement requests must be made in writing. Please complete the attached form, print it, and sign it. Forms can be mailed or hand-delivered to the following address:

Colorado Bureau of Investigation
DNA Database Section
690 Kipling Street, Suite 4000
Denver, CO 80215


The CBI has ninety days to comply with the request. You will be notified of the results of your request by first class mail.


The form must be completed and signed for each arrest where an expungement is requested.

Please type in the requested information, print the form, and sign it. Forms may also be requested in person at all CBI offices or by mail.

For questions, please call 303-239-4668 and leave a message. Your call will be returned in a timely manner.
