Zip Code Updates for MapPoint

Microsoft MapPoint

How frequently can a MapPoint end user update zip codes
in a particular US geography? Can this only happen upon
new releases, or are there downloads that I can direct a
customer to for MapPoint 2002 and/or 2004?
Hello Donna,

Unfortunately you can only get the zip code updates in MapPoint
with new releases.

Depending on what you are needing to do, you might look into
a service that will provide only the latest zip code list. Although
it couldn't be integrated with MapPoint, I think I have seen them
as little as $20.
