Locations for Area Code - 210

Area code 210 covers San Antonio and parts of its surrounding metro area in south-central Texas. Created in 1992 as a split from area code 512, it reflects the city’s rapid growth and historical significance. San Antonio, known for the Alamo, military presence, and a strong Hispanic cultural influence, has made 210 a badge of civic pride. As demand increased, 210 was overlaid with area code 726, requiring ten-digit dialing. Still, 210 remains closely associated with the city’s core identity and continues to be a sought-after code for both businesses and residents.
