Output & Result Codes

Each processed record returns a structured result (JSON or XML) containing the corrected address components plus a large set of result and enhancement fields. Most field names are self-explanatory, and most informational fields are T/F, Y/N, or blank — where blank generally means the component wasn't presented for lookup, or the address didn't assign.

Two fields tell you the outcome of a record at a glance:

• ErrStat — holds a status code when the address assigned, or an error (fault) code when it didn't.
• Fault_Code — holds the error code when the address is unassigned, and is blank when the address assigned.

In short: a blank fault code means a clean assignment; a populated fault code tells you why the address could not be assigned.

When an address assigns, the status code describes how the assigned address differs from the input. It is a positional code — each character position reports on a different group of components, so you can tell exactly what the engine changed:

Within each position, a 0 means no significant difference, and other values encode which specific components changed. The exact per-position value tables are documented in the SDK reference material.

When an address does not assign, the fault code explains why. A representative selection:

Beyond assignment, several fields characterize the matched address:

When geocoding is enabled, the assignment level tells you how precisely a coordinate was placed:

A separate centroid match level reports the precision of centroid latitude/longitude assignment. See the Address IQ geocoding overview for the concepts behind address-level and centroid geocoding.
