Below is a guide to determining or verifying whether or not your property is within the city limits
or in the unincorporated area of Mendocino County.

All assessor parcel numbers have an assigned Tax Authority Group (TAG), Tax Rate Area (TRA) or Tax Area Code (TAC) which is a six digit number with a dash (-) separating it’s three digit prefix and the last three digits. The TAG, TRA or TAC will easily determine what tax jurisdiction your property is in.

The TAG, TRA or TAC prefix designations for Mendocino County are as follows:

001-xxx ................................... within city limits of Fort Bragg
002-xxx ................................... within city limits of Point Arena
003-xxx ................................... within city limits of Ukiah
004-xxx ................................... within city limits of Willits
All other prefixes-xxx ........... unincorporated area of Mendocino County
(052-, 053-, 076-, 103-, 104-, 105-, 112-, 121-, 131-, 153-, 154-, 155-)

If you are not the property owner but need verification of the jurisdiction, please contact the
Assessor’s Office and they will provide you with documentation of the property parcel number
and TAG, TRA based on the address of the property.
