Maptitude - http://research.umbc.edu/~roswell/maptitude.html Mike: Zip+4 points (are also available on the TIGER/Line fiels from the Census Burea and can be used to pinpoint locations when a street address does not exist or is not found in the Maptitude geocoding database. If the source file to be geocoded has been processed through USPS postal standardization software, then it has zip+4 codes as a record field. If you are only interested in approximate locations (rather than address-specific), zip+4 works very well using the geocode by value feature of Maptitude. If you want to know more, send me a personal e-mail.
