Address Quality Index

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.

Two factors decide the address quality, post-processed verification match level and Matchscore.

This offers a view of overall address quality, but it is not used as a metric for deciding whether to accept an address which has been processed via Verify. Please use the AVC to verify addresses.

AQI	Address Quality	Explanation	Verification level	Matchscore
A	Excellent	Verifiable to at least Premise level without changes	>=4	100
B	Good	Verifiable to at least Thoroughfare level with minor changes	>=3	>=95
C	Average	Verifiable to at least Locality level with moderate changes	>=2	>=90
D	Poor	Only verifiable to at least Locality level with more than moderate changes	>=2	>=80
E or Empty	Bad	If an address is unable to be parsed, the AQI can be empty.	else	else
