ZIP Code Only - Code-1_Plus - 5.0

When C1CTYLKx is passed only a ZIP Code with no city/state, C1CTYLKx attempts to return a city/state for that ZIP Code, as follows:

1. If a primary city/state is found on the database for the ZIP Code, the primary city/state is returned.

2. If no primary city/state is found for that ZIP Code, the first secondary city/state combination is returned, if one exists.

3. If no primary or secondary city/state is found for the input ZIP Code, the first city/state on the database that matches the ZIP Code is returned.
