County Code is the nine-character GEO code (Geographic Code) used as the key to determine tax rates for a particular geographical area. The GEO code is defined in the format of “12-345-6789”, where the positions numbered ‘12’ represent the state, the positions numbered ‘345’ represent the county and the “6789” positions represent the city.
When defining the county code, the last four digits should contain the value ‘0000’.
