Newark, New Jersey is identified by which airport code?

Newark, New Jersey is represented by the airport code EWR, which stands for Newark Liberty International Airport. This airport code is part of the International Air Transport Association (IATA) coding system, which provides a unique three-letter identifier for airports around the world. EWR is specifically assigned to Newark Liberty, one of the oldest and busiest airports in the United States, serving as a primary hub for both domestic and international flights.

The other options do not correspond to Newark. For instance, DFW is the code for Dallas/Fort Worth International Airport in Texas, ELP refers to El Paso International Airport in Texas, and DTW represents Detroit Metropolitan Wayne County Airport in Michigan. Each of these codes identifies a different airport, highlighting how the IATA system distinctly labels airports to avoid confusion in travel and logistics. Thus, EWR is the correct and specific code for Newark Liberty International Airport, making it the right choice in this context.
