GeoCode structure

GeoCodes are numeric codes that identify tax jurisdictions by state, county, and city.

Vertex Quantum uses a 10-digit code. The structure of the code is nn-nnn-nnnn-n where the:

• first two digits (nn-) represent the state or Canada,

• third through fifth digits (-nnn-) represent a county within that state or province,

• sixth through ninth digits (-nnnn) represent a city within that county, and

• tenth digit (-n) specifies whether the location is inside or outside the city limits. (A tenth digit of 1 specifies that the location is inside the city limits; a tenth digit of 0 specifies that the location is outside the city limits.)

For example, 39-029-6350-1 is the GeoCode for the city of Berwyn in Chester County, Pennsylvania. The number 39 represents the state of Pennsylvania, 029 represents Chester County, 6350 represents the city of Berwyn, and 1 specifies that the location is inside the city limits.

Vertex O Series uses a 9-digit code using the same structure as Quantum. The difference is that O Series does not have the tenth digit indicating whether the location is inside or outside the city limits.
