What does 6666 at the end of a parcel number mean?
A parcel number is composed of a Major number (the first six digits), which identifies the plat or subdivision of the property, and a Minor number (the last four digits), which identifies a specific parcel within a plat. During conversion from paper to digital maps to build a GIS data layer of parcels, a Minor number of 6666 was given to parcels for which ownership was unknown or undetermined, and to water bodies. Department of Assessments GIS staff will eliminate these artifacts of the conversion process as they are brought to their attention. Citizens who have knowledge of the status of 6666 parcels are encouraged to submit information to the Department of Assessments. A 6666 designation does not affect taxable land value because appraisers reference the full legal property description and perform site visits to determine value.
