FAQs / Help

Who is my CLEO?

In almost all cases, the CLEO is your local or county sheriff. If there is no sheriff, the CLEO is your local chief of police, head of the state police, or state or local district attorney or prosecutor. For assistance identifying your CLEO, contact the closest police department.

Why do I need to do this?

The ATF once required that your CLEO sign off and approve your Form 1 or Form 4 applications. This is no longer required. The CLEO must still be notified that you are seeking approval to buy or build and own an NFA firearm, so the ATF requires you input their information on the application.

How to I provide my CLEO with notification?

When you complete your application, you will be able to download and print a copy of it for the CLEO. You can email or mail the copy to them, or provide it in person.

What if my CLEO refuses or returns my application?

No action is required on your part, and this does not prevent you from pursuing ownership of your NFA firearm once your application is approved. You are only required to notify the CLEO of your application. What the CLEO does with their copy of your NFA application after you make the attempt to notify is entirely on them, not you.
