Naperville City Hall Phone Directory

Naperville City Hall is at 400 S. Eagle Street, Naperville, IL 60540. The main phone number is (630) 420-6111. This is the central hub for city government.

But a direct number is faster, and the Naperville phone directory on this page gives you each one.

The City of Naperville website is the official source for all city services and contact info. You can find department pages, online forms, meeting agendas, and service request tools there. The site also has a staff directory with names and direct email addresses for key city employees. The city runs a council-manager form of government, so the city manager handles day-to-day operations while the city council sets policy.

The Naperville contact page has a full list of departments with phone numbers and email links.

That page is a quick way to find the right person when you are not sure which department handles your issue.

Naperville Government Contacts

Naperville runs on a council-manager system. The city council has nine members, including the mayor. They set budgets, pass ordinances, and approve projects. The city manager reports to the council and runs day-to-day operations. This matters for the phone directory because most service questions go to the city manager's staff, not the council.

The Naperville City Council page lists each council member with a photo and contact email. Council meetings are open to the public and happen on the first and third Tuesday of each month. You can call city hall to confirm meeting times or check the website for agendas. The government overview page breaks down how the city is structured and which departments report to whom.

This page is a good starting point if you want to know who runs each part of the city before you pick up the phone.
