In 1841, a land grant from the Mexican government to the Elias family established Los Nogales de Elias. In 1880, Russian immigrant Jacob Isaacson built a trading post at present-day Nogales. The U.S. Postal Service opened the Isaacson Post Office but renamed it as Nogales in 1883.[5]

In 1917, Nogales was the site of the last engagement in the Indian Wars.

Most of Nogales's economy is based on agribusiness and produce distributors, which comes from large farms in the Mexican agri-belt. Despite its small population, Nogales actually receives much patronage from its bordering sister-city, Nogales, Sonora, Mexico. Most observers guess the population of Nogales, Sonora, at roughly 300,000[citation needed]. International commerce is a big part of Nogales’ economy[citation needed]. More than 60 percent of Nogales’ sales tax comes from Mexican shoppers crossing the border daily[citation needed]. Nogales, Arizona, and Nogales, Sonora, are home to one of the largest maquiladora clusters[citation needed]. This enables American manufacturing plants on both sides of the border to take advantage of favorable wage and operating costs and excellent transportation and distribution networks[citation needed].

The Consulate-General of El Salvador in Nogales is located in Suite 3 at 840 North Grand Avenue.[6] The Consulate-General of Mexico in Nogales is located on 571 North Grand Avenue.[7]
