Note that for E911 purposes we are required to use the MSAG (http://netorange.com/nena-reference/index.php?title=Master_Street_Address_Guide_(MSAG)) to verify street addresses. From what my co-workers at my $DAYJOB tell me, there are many new addresses that are not resolvable.
Despite those shortcomings, E911 calls are responded to and US postal mail is delivered, specifically because a human remains involved in interpreting the information. The same needs to be done with GeoIP results.

USPS has a database of *most* of the deliverable addresses in the country. I'm in an unorganized borough. The USPS actually has no mandate, funding or lever that I can pull (that I can find) to keep their database up to date. Easily 30% of the legitimate addresses in my area are not geocodable nor in the USPS database. I suspect that there are areas of my state with an even worse percentage of unavailable data. UPS and FedEx rely on the USPS database, but will not lift a finger to fix this gap. Even as a municipal body there is no available federal mechanism for updating the database. I've tried multiple times over 15+ years. </rant> So yeah, USPS' database does have its problems. -- Jeremy Austin (907) 895-2311 (907) 803-5422 jhaus...@gmail.com Heritage NetWorks Whitestone Power & Communications Vertical Broadband, LLC Schedule a meeting: http://doodle.com/jermudgeon
