Pitney Bowes MapInfo Professional - Manual (Page 381)

You could use any one of several different region types, including county name, town name, and postal
code. Since almost all addresses contain postal codes, this is the most reliable way to refine your search.
When you set MapInfo Professional to use postal codes to refine its address matching, MapInfo
Professional will match the postal code of the target address against the postal code of the various
matching source addresses. When it finds the correct match, it is finished with the geocoding process.
MapInfo Professional can now get coordinate information from the source table and use it to place a
point object into the target table.
However, once MapInfo Professional has completed this process, many addresses may be unmatched.
You can match each one of them individually by geocoding in interactive mode. However, if you are
working with a large database, you want to do as little of this as possible. There are other ways of
improving MapInfo Professional's geocoding performance.
In the Geocode Options dialog box, you can specify that MapInfo Professional automatically pick a
different boundary, providing there is only one, from the one you specify (Use A Match Found In A
Different Boundary). You might have had MapInfo Professional geocode addresses to Northtown. One
particular address, "223 Locust Ct." is not in Northtown, but it is in Westville, and no place else. In this
case, MapInfo Professional would geocode "223 Locust Ct." to Westville. However, if MapInfo Professional
had found a "223 Locust Ct." in Westville and another one in Center Valley, it would not geocode the
address to either town. It would leave "223 Locust Ct." ungeocoded.
