ZIP Code and City/State - Code-1_Plus - 5.0

When C1CTYLKx is passed the ZIP Code and the city and state, C1CTYLKx attempts to find a match for the ZIP Code as if only the ZIP Code was passed. If a match is found, C1CTYLKx attempts to find the input city/state on the list of city/states for the input ZIP Code. If the city/state is not found within the ZIP Code, a new city/state is returned (following the rules for determining a city/state when only a ZIP Code is passed). If the input ZIP Code is not on the database, C1CTYLKx performs as if only a city and state were passed. If neither the input ZIP Code nor the input city and state are found on the database, no match is returned.
