About the 512 area code
Texas holds area code 512, which is assigned to Austin and its neighbors, among them Round Rock, Cedar Park, Georgetown, and San Marcos. The area sets its clocks to Central time.
In use since 1947 as one of the original codes, 512 has seen 210 and 361 split away over the years and gained 737 as an overlay covering the same footprint. That overlay is the reason local calls take ten digits.
Dialing note: 512 is part of an overlay complex with 737, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
