Precision
Ping Geocoding's Precision value indicates the resolution of the matched entity, ranging from 0 to 100. Higher values signify a more precise match, while lower values denote a less precise match.
- Higher Precision Values: These generally correspond to smaller matched geo-entities. A maximum precision value of 100 typically means that Ping Geocoding matched the input address to a specific, unambiguous building rooftop.
- Lower Precision Values: These correspond to larger matched geo-entities. For example, a precision value of 70 or less might indicate a match to an entire postcode, city, or administrative region. This often suggests a partial match, such as when only the postcode is matched and not the street.

💡 **Examples:
- Tempe, AZ**: Precision will likely be 70 or lower
- 285 Fulton St, New York, NY 10007: Precision will likely be the maximum of 100

Confidence
Ping Geocoding's Confidence value indicates the likelihood that:
- The matched geo-entity is indeed the entity specified in the address.
- The latitude/longitude pin is correctly placed.
The confidence values also range from 0 to 100, with larger values indicating a higher likelihood of an accurate match and correctly placed pin.
Potential Sources of Ambiguity:
- Multiple Locations: For example, "123 & 234 Easy Street, New York, NY" refers to two different locations. Since Ping Geocoding matches one location per input, the confidence may be lower due to uncertainty.
- Similar Addresses: An address like "35 K St, Washington, DC" could refer to either "35 K St NW" or "35 K St NE," which are over 4000ft apart. This could lower the confidence of the geocode.
- Large Complexes: For example, "868 W Peters Rd, Casa Grande, AZ 85122" is a large warehouse complex. Even with a high precision rooftop match, the confidence might be lower due to the difficulty of accurately placing the latitude/longitude pin.
