The Story Behind Area Code 210

Area code 210 was introduced on November 1, 1992, when it split from the original 512 plan to serve the booming San Antonio metro area Wikipedia At the time, 512 had covered central and south Texas since 1947, and regulators chose to let Austin keep 512 while carving out 210 for San Antonio—ensuring minimal disruption to state government agencies. Just five years later, surging demand led to a three-way split in July 1997: the Hill Country suburbs adopted 830, the Rio Grande Valley became 956, and 210 remained anchored in Bexar County Wikipedia

In October 2017, as projections indicated exhaustion by mid-2018, the Texas Public Utility Commission approved an overlay of area code 726 atop 210. Permissive ten-digit dialing began in March 2017, with mandatory dialing mandated by September—preserving 210 as a symbol of San Antonio identity while expanding number availability for new subscribers Wikipedia

Today, area codes 210 and 726 together serve over 2 million residents across Bexar, Atascosa, Comal, Guadalupe, Medina, and Wilson counties. From downtown office towers to suburban neighborhoods like Alamo Heights, Universal City, and Converse, a 210 number signals true local presence—a crucial advantage for businesses and organizations aiming to connect authentically with the San Antonio community Wikipedia
