Where 512 is.
512 is one of the original 1947 codes. It once covered a wide stretch of South Central Texas, including San Antonio and Corpus Christi. San Antonio moved to 210 in 1992 and Corpus Christi to 361 in 1999, so 512 now centers on Austin.
The 737 overlay went into service in 2013. New numbers in Austin and its suburbs can start with either 512 or 737.
