Take a look inside Hidalgo City with us! This community under the zip code 78557 has a median household income considered as below the state average, which is also the case with the median age, and the length of stay since moving to this corner of Texas. Interesting huh? On the other hand, some notable locations in this municipality situated near Granjeno, McAllen, Pharr, San Juan, Mission, South Alamo, and North Alamo are Pharr San Juan Pumping Station, Hidalgo Public Library, Dodge Arena, Hidalgo Pump House Heritage, Lake Tropicana, Lake Texano, and Old Hidalgo Courthouse.
