What is the city code for Albuquerque, New Mexico?

Albuquerque, New Mexico, is served by the airport with the code ABQ, which stands for Albuquerque International Sunport. City codes are often derived from the first few letters of the city's name along with distinguishing characters that differentiate them from other locations. In this case, 'ABQ' uses the 'A' from 'Albuquerque,' the 'B' from the second letter, and 'Q' to complete the three-letter code.

The other options represent different cities: ATL is the code for Atlanta, Georgia; BOS is for Boston, Massachusetts; and DEN is for Denver, Colorado. Each of these cities has its own unique three-letter city code, which does not correspond to Albuquerque, reinforcing the importance of memorizing these codes for travel and airport navigation.
