What is a Parcel?
A parcel is a piece of land, regardless of size, under one ownership. In maintaining land ownership records, the assessor defines the boundaries of land according to ownership and assigns a unique identifying number to each parcel: the parcel number, parcel identifier or parcel identification number (PIN).
This numbering becomes the universal tie for other agencies needing access to information relating to properties, e.g. taxes, special assessments, zoning, Realtor listing information, water utility ties, mortgages, liens, etc.
