Where Is Area Code 505?

Updated: January 25th 2021

Area code 505 is the area code for the northwestern and central portions of New Mexico. When area code 505 was put into service on January 1, 1947, it originally covered all of New Mexico because it was New Mexico’s original area code. When New Mexico experienced ample growth in population and telephone use, area code 505 was split to form area code 575 in 2007. Area code 505 is located in the Mountain Time Zone and covers 12 counties of New Mexico.

Albuquerque is the most populous city in New Mexico and is the county seat of Bernalillo County. Albuquerque was named in recognition of Francisco, Duke of Albuquerque. Albuquerque is situated in the central part of New Mexico and has one of the highest elevations of any major city in the United States. The city’s location in the northern tip of the Chihuahuan Desert, near the boundary of the Colorado Plateau, gives it its cold semi-arid climate. Running along the eastern side of Albuquerque is the Sandia Mountains while the Rio Grande flows through the city. Going back in history, Native Americans had lived along the Rio Grande for centuries before European settlers arrived. In 1706, Albuquerque was founded as the Spanish colonial outpost of Villa de Albuquerque and was strategically located along the Camino Real. Albuquerque got its start as a town when the Atchison, Topeka and Santa Fe Railway depot was built in 1880. Albuquerque was incorporated as a town in 1885 and then was incorporated as a city in 1891. By 1900, Albuquerque had an electric street railway, a multimodal transit hub, and the University of Mexico. In 1926, the first travelers on U.S. Route 66 appeared in Albuquerque; with their arrival came numerous motels, restaurants, and gift shops along the roadside.

Albuquerque has a population of 545,852 and the racial makeup of the city is 69.7% White, 46.7% Hispanic, 4.6% Native American, 3.3% African American, and 2.6% Asian (2010 Census). Unfortunately Albuquerque is among the top ten most dangerous cities in New Mexico.

The University of New Mexico is located in Albuquerque and is the largest public flagship university in New Mexico. When it comes to the economy, industrial output is centered on Albuquerque; the city is also at the center of the New Mexico Technology Corridor. With so many things to do and see in Albuquerque, some of the major points of interest in the city include the Sandia Peak Tramway, the Albuquerque Biological Park, the Indian Pueblo Cultural Center, the National Museum of Nuclear Science & History, the Petroglyph National Monument, and the New Mexico Museum of Natural History and Science.
