Mendocino County Information Services — GIS
Official geographic information and map-access function. A county association identifies the published provider/referral context; it does not assert legal map boundaries, county planning authority inside cities, or complete coverage of every layer.
Information Services' map guide explains eight-digit APN/address searching and the Assessor's Parcel Number layer. This is GIS parcel-map information; the county expressly rejects its use for determining property boundaries or financial decisions.
- Availability · Published APN format; no parcel queried
- The APN must be eight digits (e.g. 11122203). If it exceeds this length you may need to remove the last 2 numbers.
