USA Zip Codes is a simple reference app that lists zip codes in the United States along with the major town or city associated with that code.

Users can find out which major town or city a zip code is in and view it on a map.

Features :-

- Search by zip code.
- Search by town name.
- 0ver 40,000 entries.
- Designed for both iPad and iPhone.
- View the zip code location (nearest major town) on a map.
- Switch the search keyboard mode between QWERTY or NUMERIC for easier, faster searching.
- Supports all device orientations on both iPhone and iPad
- No data connection is necessary to view the codes and towns but if you wish to view the town on the map, a data connection will be required.

Please note that there can be several town entries per zip code. For example Cheyenne has several codes associated with it in the range 82001 - 82010 so 'Cheyenne' will appear 8 times in the list.

For users with older, slower devices (pre iPhone 4), it is possible to turn off the 'dynamic search' feature (where the list is filtered as you type the search text) and instead enter a full search text before tapping 'search'

iOS 4.1 is required.
