Global Address Verification:FAQ

Result Codes

How do I use Results Codes for the Global Address Web Service?

The Global Address Web Service will return a number of codes to inform you of the status of an global address. These codes can be divided into AV codes for status, AE codes for errors, and AC codes for changes.

AV Codes

These codes tell you how good the returned address is. They are slightly different than the AS codes you are used to in our US only products.

• AV2X denotes an address that has been fully verified.
• AV1X denotes a partially verified address, but something was invalid.
• The second number (X) indicates the level of verification to which the output address is valid up to. The possible values from between 1 to 5.

For example

1. AV25 indicates the output address was fully verified to the SubPremises(level 5.)
2. AV24 indicates the output address was fully verified to the Premises(level 4.)
3. AV22 indicates the output address was fully verified to the Locality(level 2.) but we did not have data above the locality.
4. AV14 indicates the output address was partially verified but is good up to the Premises(level 4.) You can imply that this means something was wrong with the sub-premise.
5. AV13 indicates the output address was partially verified but is good up to the Thoroughfare(level 3.) You can imply that this means something was wrong with the premise.

AV24 vs AV25

Both of these codes are similar in that they tell you the address is fully good down to the delivery address. You will get an AV24 if the destination address is a house or building without any sub-premises (therefore level 5 is impossible). AV25 means the address was fully good and that the destination address does contain sub-premises. If you have a apartment complex and you enter a wrong suite, you will get an AV14 (partially good address, good to the premise).

Using the AV Codes

One use of the AV codes is to simply look for AV2. This will indicate that all addresses have been fully verified with no errors up to the data available. However, if you want to ensure all addresses are correct down to the delivery address, you should look for AV24 or AV25.

AE Codes

AE codes will tell you what type of error occurred when verifying the address. It is possible to get AE codes along with AV codes (like Sub-premise invalid, multiple match) or AE codes by themselves (postal code error).

AC Codes

AC codes will tell you what we changed in the output address when compared to the input address. Standardizations (Street to St) do not count as changes.
