Real Property Search
Parcel Numbers
Clairmont County parcel numbers take the form DD-MMM-LLLL — a two-digit
taxing district, three-digit map number, and four-digit lot number, always written with
leading zeros (for example, 03-104-0221). Your parcel number is printed in the
upper left of your semi-annual tax bill. Parcel numbers are the most reliable way to research
a property in the Real Property Search and in
records maintained by other county offices.
