Frequently Asked Questions (FAQs)

What is considered valid identification?

According to the Federal Firearms Regulation Reference Guide: The identification document presented by the purchaser must have a photo of the purchaser, name, address, and date of birth, and must be issued by a governmental entity for the purpose of identification of individuals. (e.g. Drivers License) Currently, Colorado Concealed Handgun permits do not constitute a valid ID for the purposes of the firearms background check. However, a Colorado Concealed Handgun permit with a current address may be used to establish residence when the valid ID does not.

If a buyer has a Colorado Concealed Handgun Permit (CHP), do I still process a background check for them to purchase a firearm?

Yes. A Colorado Concealed Handgun Permit (CHP) does not meet all the criteria to qualify for an exemption to the FBI NICS background check. That means even if the buyer has a Colorado Concealed Handgun Permit  (CHP) you must process a background check in accordance with state and federal law every time they purchase a firearm. Out of state Concealed Handgun permit holders also need a background check to purchase a long gun in Colorado.
