Reference GuideResponse Results CodesAppendixAVXX Verification Codes• AV2X denotes an address that has been verified to the highest possible level with thereference data.• AV1X denotes a partially verified address, but NOT to the highest level possible withthe reference data.• The second number indicates the level of verification. There are five levels:• Administrative Area(level 1) verification is the most general verification area, withSubPremises(level 5) being the most specific area.• Ideally, all addresses should be verified to Premises(level 4) or SubPremises(level 5.)However this is dependent on the quality of the address data and the countries’reference data. Some countries lack enough data to be verified to the SubPremises.They may only have data to the Locality(level 2.) This is why it is possible to have anAV22 code. The address has been verified up to the Locality and the reference dataonly has verification up to that level.• For example:a. AV25 indicates a maximum possible verification to the SubPremises(level 5.)b. AV24 indicates a maximum possible verification to the Premises(level 4.)c. AV22 indicates a maximum possible verification to the Locality(level 2.)This can occur if the reference data only contains data up to the Locality level.d. AV14 indicates a partial verification to the Premises(level 4.) This indicates thatthe reference data has verification up to the SubPremises(level 5.)41
