The Verification engine is used to verify and correct whole addresses. However, the user may not always provide enough information to the Verification engine to enable it to produce a single verifiable match.
An address can be matched to one of a set of verification levels. The verification levels are returned by the Verification engine, and indicate the degree of confidence in the returned match.
The verification levels that can be returned are as follows:
The address searched upon was matched to a single deliverable address in the data. The verified result may be slightly different from the address entered and searched upon, as any formatting and spelling errors will have been corrected, and any missing elements will have been added.
The address searched upon was matched to a single deliverable address in the data, although the engine is less confident about the match than for the "Verified" level above, and therefore user interaction is recommended to confirm that it is the correct address.
The address searched upon was not matched to a complete deliverable result in the data, and instead has been matched to a partially-complete address.
The address searched upon was not matched to a complete deliverable result in the data, and instead has been matched to a partially-complete address.
The address searched on was matched equally to more than one result. The correct address must be selected from a list of possible matches.
