Note that for E911 purposes we are required to use the MSAG (http://netorange.com/nena-reference/index.php?title=Master_Street_Address_Gu...)) 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.

Please don't guess (like, you know, MaxMind does.) USPS has its own database of all of the deliverable addresses in the country. They have their problems, but give or take data staleness as buildings are built or demolished, that's not one of them.
A qualifier. 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 jhaustin@gmail.com Heritage NetWorks Whitestone Power & Communications Vertical Broadband, LLC Schedule a meeting: http://doodle.com/jermudgeon
