, Corpus Christi, Brownsville, Harlingen, and McAllen. Despite the presence of San Antonio and Austin—the state's third- and fourth-largest cities, respectively, for most of the second half of the 20th century—this configuration remained in place for 45 years. In 1992, the western part of its territory, including San Antonio and the Rio Grande Valley, became area code 210, making 512 the last of Texas' original four area codes to be split. Typically, the largest city in an existing area code keeps the original code, which in this case would have been San Antonio. However, state regulators decided that having the Austin area keep 512 would spare the large number of state agencies in and around the state capital from the expense and disruption of changing their numbers. On February 13, 1999, the 512 area code was reduced to its current size when the southern portion (including Corpus Christi) became 361. To stave off exhaustion by the end of 2013, area code 737 was introduced as an
