Platte County Assessor's Office

Real Property Change of Address


The Platte County Assessor is required to mail an Notice of Increase Valuation to all property owners of record at the last known address. It is important that we have your current mailing address to avoid unnecessary delays in delivery. It is the owner’s responsibility to advise the Assessor when the mailing address has changed. Please use this form to report a change in address. If you have any questions regarding the form, please call (816) 858-3316.
