Final Characters in the Address ID Value
When you verify an address in batch or interactive mode, Address Verification returns an address ID with the final character A, B, C, or D. The final character identifies the types of information that the address contains.
The final character identifies the following combinations:
A: Current post code, current street-based address
B: Current post code, lot-based address
C: Old post code, current street-based address
D: Old post code, lot-based address
To obtain a different combination of address data, replace the final character in the address ID value with the character that represents the combination that you require. Then enter the modified address ID in address code lookup mode.
When you specify B or D as the final character, Address Verification returns the address of the lot on which the building is located. A lot-based address does not contain building information, and Address Verification can validate a lot-based address without building information.
When you specify A or C as the final character, Address Verification returns the current version of the address, including any applicable building information. If you update the final character in the address ID of a lot-based address to A or C, Address Verification returns multiple addresses if multiple buildings stand on the lot. You can submit each address with building information to retrieve a unique address ID for the address.
