For every result, Geocodio will give you an accuracy type and an accuracy score. We recommend using a combination of the accuracy score and accuracy type to evaluate and filter the returned results.
Accuracy types include:
rooftop: on the exact parcel
point: generally, in front of the parcel on the street
range_interpolation: generally, in front of the parcel on the street
nearest_rooftop_match: the nearest rooftop point if the exact point is unavailable
intersection: An intersection between two streets
street_center: A central point on the street
place: zip code or city centroid
county: county centroid
state: state centroid
For reverse geocoding, the following accuracy types may be found as well:
nearest_street: Nearest match for a specific street with estimated street number
nearest_place: Closest city/town/place
Given a random sample of addresses evenly distributed across the US, you can expect 70% of results to be rooftop, 20% to be range interpolated, and 10% to be other accuracy types.
Accuracy scores are a reflection of the amount of differences between the input and the output. We generally recommend using results with an accuracy score above 0.8. Results below that threshold can indicate potential issues, such as formatting issues or incomplete addresses.
Example: 47 N State St, Lake Oswego, OR 97034
