I’ve known about this for a while now, but today I guess I can publicly mention it. Leopard’s Address Book has replaced MapQuest with Google Maps as it’s built-in mapping service. It doesn’t do directions though, and my Google Maps Plugins are completely compatible with Leopard, so you can continue to use them if you rely on having directions available from the context menu.
However, this post is not about my Google Maps Plugin, rather, it’s about PostCheck! Leopard’s built-in Google Maps function works best when your address are formated properly using USPS standards. (My Google plugins work best if they are too, but have ways to get around some common issues.) PostCheck will format your US addresses to proper standards and fill in missing information such as ZIP+4 codes.
Once your addresses have been formated with PostCheck, Google will have much more success finding it. Give the demo version a try and if you like you what you see, the full version is only $10 and includes the time saving batch lookup feature to get all of your address up-to-date.
