About CLEO Notification

When you file an ATF Form 4 (transfer) or Form 1 (manufacture) for an NFA item, you must notify your Chief Law Enforcement Officer (CLEO). For most people, this is your county sheriff.

  • CLEO notification is required but approval is not
  • The ATF automatically sends notification via eForms
  • You may also mail a copy of your form to the CLEO
  • This address is for notification purposes only
