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.
