The Address Quality Index (AQI) is used to indicate the quality of an address, e.g., Excellent quality, Good quality, Average quality, Poor quality, and Bad quality. Any record that is able to be parsed will have an AQI. The AQI is derived from the AVC, using the following table:
AQIAddress QualityExplanationVerification levelMatchscore
AExcellentVerifiable to at least Premise level without changes>=4100
BGoodVerifiable to at least Thoroughfare level with minor changes>=3>=95
CAverageVerifiable to at least Locality level with moderate changes>=2>=90
DPoorOnly verifiable to at least Locality level with more than moderate changes>=2>=80

Example: Excellent Quality

{
   "Address1":"999 Baker Way, San Mateo, CA, 94404, US"
}​
The address is verified to the Premise level without changes. From the output below, we can see the post-processed verification match level is 4, and the Matchscore is 100, the Address Quality Index is A.
