New Address Assignment and Verification

Before filling out either the new address assignment application or the address verification form, make sure you’ve got:

  • A copy of the current property deed (or recorded document number) and a certified site plan showing the layout of where the building is to be erected
  • The property tax number (parcel number), ex. 00-00-00-000-000-0000
  • Information on the property’s current zoning

Normally, each address assignment requires an on-site visit from County personnel. Please provide complete details as to the exact location for the address specified.

You may pick up your address at:

Will County 9-1-1 Office

Suite 102

For questions pertaining to Property Addresses please contact the Addressing hotline at 779-379-9911 or email us at

The address is available 10 working days after your application is received by the 9-1-1 Administration Office. We may also mail, fax, or email the address to you if you so request on the form.
