How to Join NACo

County governments are the members of NACo. Once a county is a member, the benefits extend to all of the county's officials and staff. Dues are based on a county's 2010 Census population numbers and follow the calendar year — January through December.

Joining NACo is simple. Request an invoice and one will be sent. Once the invoice is paid, a welcome packet will be sent to the county with information about NACo member benefits, programs and resources that are available, along with tips on how to become involved.

NACo’s ability to listen to its members discuss and debate critical issues, and then craft strategies and messages that are fair, responsive, and that also resonate with the agencies and congressional members, is exceptional.

Counties are in a powerful position to bring solutions to policymakers. The more county elected leaders can participate in NACo, the stronger the organization will become. Bottom line — the stronger and more persuasive NACo is, the better we are able to serve our constituents.

- Hon. Mandy R. Metzger, Supervisor, Coconino County
