Which city is denoted by the city code CUN?

The city code CUN corresponds to Cancun, Mexico, a popular beach destination known for its resorts, vibrant nightlife, and access to the Caribbean Sea. Cancun is located in the Quintana Roo state and serves as a major hub for travelers seeking sun, sand, and various water activities. Recognized internationally, the airport serving Cancun (Cancún International Airport) is one of the busiest in Latin America, further solidifying its importance as a travel destination.

In contrast, the other choices do not correctly match the city code CUN. Coastal City, Nicaragua, is not represented by CUN, and neither Dallas, TX, nor Corpus Christi, TX, has that designation. Understanding city codes is crucial for travelers and industry professionals, as they provide a standardized way to identify locations quickly and efficiently.
