The Assessor is responsible for identifying the property owner and listing the address. All address changes are processed through the Assessor's Office at:
P.O. Box 168
Bisbee, AZ 85603
The property owner should write to that office to change the address listed on the tax notice and/or valuation notice. If the Treasurer's office receives the written change of address, the information is forwarded to the Assessor's Office.
