Area Code 210
Area code is a numbering system that facilitates telephonic communication across all the states of the United States of America. The area code 210 serves the state of Texas and it is one of the busiest area codes in the United States of America. The system of area codes was developed by the AT&T and Bell Laboratories in the 1940’s. Prior to the development of the area codes the states and the provinces used one number as their telephone codes. After this the three digit area codes were devised to be used by the states and provinces. This was a unique system wherein all the states and provinces in the United States of America were provided with three digit area codes. The states and provinces that used only one area code were provided with numbers whose middle digit was 0. The states and provinces that used more than one are codes were provided with 1 as the middle digit. This numbering system is popularly known as the North American Numbering Plan and abbreviated as NANP. This plan was implemented in the year 1947 and has remained unchanged till date. NANP is one of the most efficient and comprehensive telephone numbering systems ever developed in the world.
