Provides 2 methods to lookup zip codes in the United States:
1. By 5-digit zip code
2. By City and State
Lookup by zipcode may show more than one result. This is due to the same zip code being assigned to a city and perhaps a university or IRS address.
CIty and State lookup allows you to type in part of the city name if you're not sure how to spell it.
Lookup by city and state can possibly return up to 30 rows. This is because of the postal office delivery and routing mechanism.
The result window is scrollable if many rows are returned.
Database resides on hosted site and contains 80,000 rows of U.S. zipcode data.
Should work on any phone running Android 2.2
