A geocode contains 17 digits. For a reliable search using the geocode, use only (but no less than) the first 8 digits of the code.

The first 2 digits identify the county, so any geocode for Yellowstone County will start with "03".

The next four digits identify the township and range, for example: Township 1 North, Range 26 East would be identified as "1033" in the geocode. You will find the four digit geocode number listed below the township and range on the following map.

The following 2 digits identify the section number. (Section 21 is identified as "21") All single digit sections must have a preceding zero. For example, Section one would be identified as "01".

The remaining 9digits are not reliable to find property geographically.

In order to search for property in T1N, R26E, section 21, you would enter "03103321" in the Geo Code box of the search form, and depending on the area, you could get from 1 to several thousand geocodes returned with your search.
