Area code 505 originally covered all of New Mexico when it was established in 1947. It was not until 2007 that New Mexico experienced sufficient growth in population and telephone use to need an additional area code. It was at that time that area code 505 was split to form area code 575. Our new collection "The Five" represents the entire state of New Mexico. From Shiprock, to Albuquerque, and all the way to Jal, this design was created for all of the beautiful people in this great state. This one's for the 5!
