Appeals Information

The Appeals Section works with individuals who are denied the ability to purchase a firearm and appeal to the Colorado Bureau of Investigation (CBI) for reconsideration. Upon receiving the person's request to appeal within 30 days of being denied, will review the denial, conduct any necessary research and return a final determination. In many cases, the Appeals section is able to overturn a denial based on additional information provided by the appellant or obtained by the CBI as a result of the appeals process.

On many occasions, the Appeals section has been able to work with the appellant to correct or update erroneous or missing information from the record. This may not only result in an overturned denial, but also assist in the correction of erroneous information which could otherwise have a negative impact on things such as professional licensing, housing, and employment.

If you have been denied by the CBI for the purchase of a firearm, you have the right to appeal the decision. In accordance with both state and federal privacy laws, we are unable to disclose the reason(s) for your denial over the telephone, nor do we handle appeals in person.

Starting on August 9, 2021, the CBI InstaCheck section initiated an online appeal system for denied firearm purchases. This system is available at the following website address:


Here you will be able to submit an appeal to CBI and then receive communication including status updates from the CBI during the process. You will need to create an account on this website for the purpose of submitting an appeal to CBI. You MUST submit your intent to appeal within 30 days of your denial.  There are further details available on the website.

CBI InstaCheck will also accept appeal form submissions by mail (please use the form below). You MUST submit your intent to appeal within 30 days of your denial.

If you attempt to submit an appeal by any other means, besides the online system or by mail, the appeal will not be processed.
