History of Area Code 737
Area code 737 entered service on July 10, 2013, as an overlay for area code 512. It was not created by splitting the 512 territory, so existing 512 customers could keep their telephone numbers.
Area code 512 was one of the original Texas area codes assigned when the North American Numbering Plan began in 1947. Later regional splits reduced the territory covered by 512. Continued demand for numbers from population growth, businesses, wireless service, and additional telephone lines led to the 737 overlay. The overlay added number capacity without changing the region's geographic boundaries.
